Abstract
An auxin-producing bacterial strain, CC-SYL302T, was isolated from paddy soil in Taiwan and identified using a polyphasic taxonomic approach. The cells were observed to be aerobic, non-motile, non-spore-forming rods, and tested positive for catalase and oxidase. Produced carotenoid but flexirubin-type pigments were absent. Optimal growth of strain CC-SYL302T was observed at 25 °C, pH 7.0, and with 2% (w/v) NaCl present. Based on analysis of 16S rRNA gene sequences, it was determined that strain CC-SYL302T belongs to the genus Flavobacterium of the Flavobacteriaceae family. The closest known relatives of this strain are F. tangerinum YIM 102701-2 T (with 93.3% similarity) and F. cucumis R2A45-3 T (with 93.1% similarity). Digital DNA-DNA hybridization (dDDH) values were calculated to assess the genetic distance between strain CC-SYL302T and its closest relatives, with mean values of 21.3% for F. tangerinum and 20.4% for F. cucumis. Strain CC-SYL302T exhibited the highest orthologous average nucleotide identity (OrthoANI) values with members of the Flavobacterium genus, ranging from 67.2 to 72.1% (n = 22). The dominating cellular fatty acids (> 5%) included iso-C14:0, iso-C15:0, iso-C16:0, iso-C15:0 3-OH, iso-C17:0 3-OH, C16:1 ω6c/C16:1 ω7c and C16:0 10-methyl/iso-C17:1 ω9c. The polar lipid profile consisted of phosphatidylethanolamine, an unidentified aminolipid, an unidentified aminophospholipid, and nine unidentified polar lipids. The genome (2.7 Mb) contained 33.6% GC content, and the major polyamines were putrescine and sym-homospermidine. Strain CC-SYL302T exhibits distinct phylogenetic, phenotypic, and chemotaxonomic characteristics, as well as unique results in comparative analysis of 16S rRNA gene sequence, OrthoANI, dDDH, and phylogenomic placement. Therefore, it is proposed that this strain represents a new species of the Flavobacterium genus, for which the name Flavobacterium agricola sp. nov. is proposed. The type strain is CC-SYL302T (= BCRC 81320 T = JCM 34764 T).

Expanding success in the isolation of abundant marine bacteria after reduction in grazing and viral pressure and increase in nutrient availability. Microbiol Spectr 2023; 11:e0089023. [PMID: 37747249 PMCID: PMC10580928 DOI: 10.1128/spectrum.00890-23] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/28/2023] [Accepted: 08/03/2023] [Indexed: 09/26/2023] Open
Abstract
Isolation of microorganisms is a useful approach to gathering knowledge about their genomic properties, physiology, and ecology, in addition to allowing the characterization of novel taxa. We performed an extensive isolation effort on samples from seawater manipulation experiments that were carried out during the four astronomical seasons in a coastal site of the northwest Mediterranean to evaluate the impact of grazing, viral mortality, resource competition reduction, and light presence/absence on bacterioplankton growth. Isolates were retrieved using two growth media, and their full 16S rRNA gene was sequenced to assess their identity and calculate their culturability across seasons and experimental conditions. A total of 1,643 isolates were obtained, mainly affiliated to the classes Gammaproteobacteria (44%), Alphaproteobacteria (26%), and Bacteroidia (17%). Isolates pertaining to class Gammaproteobacteria were the most abundant in all experiments, while Bacteroidia were preferentially enriched in the treatments with reduced grazing. Sixty-one isolates had a similarity below 97% to cultured taxa and are thus putatively novel. Comparison of isolate sequences with 16S rRNA gene amplicon sequences from the same samples showed that the percentage of reads corresponding to isolates was 21.4% within the whole data set, with dramatic increases in the summer virus-reduced (71%) and diluted (47%) treatments. In fact, we were able to isolate the top 10 abundant taxa in several experiments and from the whole data set. We also show that top-down and bottom-up controls differentially affect taxa in terms of culturability. Our results indicate that culturing marine bacteria using agar plates can be successful in certain ecological situations. IMPORTANCE Bottom-up and top-down controls greatly influence marine microbial community composition and dynamics, which in turn have effects on their culturability. We isolated a high amount of heterotrophic bacterial strains from experiments where seawater environmental conditions had been manipulated and found that decreasing grazing and viral pressure as well as rising nutrient availability are key factors increasing the success in culturing marine bacteria. Our data hint at factors influencing culturability and underpin bacterial cultures as a powerful way to discover new taxa.

Abstract
A polyphasic taxonomic approach was used to characterize a novel bacterium, designated strain CC-YST710T, isolated from poultry manure sampled in Taiwan. Cells of strain CC-YST710T were aerobic, Gram-stain-negative, nonmotile, nonspore-forming rods, displaying positive reactions for catalase, and oxidase activities. Strain CC-YST710T was found to grow optimally at 30°C, pH 7.0, and in the presence of 2% (w/v) NaCl. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine, two unidentified phospholipids, four unidentified aminolipids, one unidentified aminophospholipid, and five unidentified lipids. The major polyamine was spermidine. The dominating cellular fatty acids (> 5%) included C16:0, C18:0, and C18:1ω7c/C18:1ω6c. Based on 16S rRNA gene analysis, this isolate showed the closest phylogenetic relationship with 'Pseudogemmobacter humicola' (97.6%), followed by Pseudogemmobacter bohemicus (97.2%) and 'Pseudogemmobacter hezensis' (97.5%). The draft genome (4.3 Mb) had 62.9 mol% G + C content. CC-YST710T can be distinguished from other Pseudogemmobacter species due to the exclusive presence of key genes encoding p-hydroxybenzoate hydroxylase, protocatechuate 3, 4-dioxygenase (α and β chain), and homogentisate 1, 2-dioxygenase involved in the degradation of phenolic compounds such as p-hydroxybenzoic acid, protocatechuate, and homogentisate, respectively. Orthologous average nucleotide identity (OrthoANI) of the isolate with the type strains of the genera Pseudogemmobacter were 77.6%‒78.0% (n = 3), followed by Tabrizicola (72.3%‒73.7%, n = 5), and Gemmobacter(72.3%‒73.5%, n = 7). Based on its distinct phylogenetic, phenotypic, and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence, OrthoANI, digital DDH, and the phylogenomic placement, strain CC-YST710T is considered to represent a novel Pseudogemmobacter species, for which the name Pseudogemmobacter faecipullorum sp. nov. (type strain CC-YST710T = BCRC 81286T = JCM 34182T).

Abstract
A polyphasic taxonomic approach was used to characterize a Gram-stain-negative, orange-coloured bacterium (designated strain CC-SYL272T) isolated from paddy soil. Cells were observed to be strictly aerobic, non-motile and non-spore-forming rods, exhibiting positive catalase and oxidase. Strain CC-SYL272T was found to grow optimally at 20–40 °C, pH 6.0–8.0 and NaCl 0–2 % (w/v). Phylogenetic analysis based on 16S rRNA gene sequences indicated that strain CC-SYL272T belongs to the genus
Niabella
, family
Chitinophagaceae
, and is most closely related to
Niabella pedocola
(97.8 %) followed by
Niabella drilacis
(97.2 %) and established a distinct taxonomic lineage associated with these species. The highest orthologous average nucleotide identity (OrthoANI) values were recorded for strain CC-SYL272T
versus Niabella species (69.1–83.5 %, n=8). The mean digital DNA–DNA hybridization (dDDH) value obtained for strain CC-SYL272T against
N. pedocola

Abstract
Throughout history, nature has been acknowledged for being a primordial source of various bioactive molecules in which human macular carotenoids are gaining significant attention. Among 750 natural carotenoids, lutein, zeaxanthin and their oxidative metabolites are selectively accumulated in the macular region of living beings. Due to their vast applications in food, feed, pharmaceutical and nutraceuticals industries, the global market of lutein and zeaxanthin is continuously expanding but chemical synthesis, extraction and purification of these compounds from their natural repertoire e.g., plants, is somewhat costly and technically challenging. In this regard microbial as well as microalgal carotenoids are considered as an attractive alternative to aforementioned challenges. Through the techniques of genetic engineering and gene-editing tools like CRISPR/Cas9, the overproduction of lutein and zeaxanthin in microorganisms can be achieved but the commercial scale applications of such procedures needs to be done. Moreover, these carotenoids are highly unstable and susceptible to thermal and oxidative degradation. Therefore, esterification of these xanthophylls and microencapsulation with appropriate wall materials can increase their shelf-life and enhance their application in food industry. With their potent antioxidant activities, these carotenoids are emerging as molecules of vital importance in chronic degenerative, malignancies and antiviral diseases. Therefore, more research needs to be done to further expand the applications of lutein and zeaxanthin.

Abstract
A polyphasic taxonomic approach was used to characterize a Gram-stain-negative bacterium, designated strain CC-CFT501T, harboring xenobiotic- and allelochemical-metabolizing genes, isolated from a long-term ecological research field in Taiwan. Cells of strain CC-CFT501T were catalase- and oxidase-positive, non-motile and short rods. Optimal growth occurred at 30 °C, pH 8 and 1% NaCl. Strain CC-CFT501T was found to share high 16S rRNA gene sequence similarity with the members of genera Quisquiliibacterium (94.3%, n = 1), Pandoraea (93.4-94.0%, n = 23) and Paraburkholderia (93.3-94.0%, n = 9), affiliated to the family Burkholderiaceae. Strain CC-CFT501T shared 76.4% orthologous average nucleotide identity (OrthoANI) and 20.9% digital DNA-DNA hybridization (dDDH) values with Quisquiliibacterium transsilvanicum DSM 29781T. Draft genome sequence (3.83 Mb) of strain CC-CFT501T revealed several genes encoding the proteins involved in biphenyl and phenolic acid metabolism. Fatty acid profile contained C16:0, C18:0, C10:0 3-OH, C16:1 ω7c/C16:1 ω6c and C18:1 ω7c/C18:1 ω6c in predominant amounts. The polar lipid profile consisted of phosphatidylethanolamine, thirteen unidentified amino lipids, two unidentified phospholipids and two unidentified glycolipids. The major polyamine was spermidine and ubiquinone Q-8 was the sole respiratory quinone. The DNA G + C content was 70.0 mol%. Based on its distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence, ANI and dDDH analyses, strain CC-CFT501T is considered to represent a novel genus and species of the family Burkholderiaceae, for which the name Zeimonas arvi gen. nov., sp. nov. is proposed. The type strain of the type species is CC-CFT501T (= BCRC 81218T = JCM 33506T).

Abstract
Microbial community structures associated with halophytes and their compositions among different habitats, particularly natural saline sites, have not yet been investigated in detail. In the present study, we examined the diversity and composition of the rhizosphere and root endosphere bacteria of two halophytes, Salicornia europaea L. and Glaux maritima L., collected from two adjacent brackish lakes, Lake Notoro and Lake Tofutsu, in Japan. The bacterial species richness and diversity indices of the two halophytes collected from both lakes showed no significant differences in the rhizosphere or root endosphere. In contrast, beta diversity and taxonomic analyses revealed significant differences in the bacterial communities from each halophyte between the two lakes even though the two locations were natural saline sites, indicating that the bacterial communities for S. europaea and G. maritima both fluctuated in a manner that depended on the geographical location. Common and abundant genera associated with each halophyte across the two lakes were then identified to verify the bacterial genera specifically inhabiting each plant species. The results obtained showed that the composition of abundant genera inhabiting each halophyte across two lakes was distinct from that reported previously in other saline soil areas. These results suggest that each halophyte in different geographical sites had an individual complex bacterial community.

Abstract
Marine bacterial species contribute to a significant part of the oceanic population, which substantially produces biologically effectual moieties having various medical and industrial applications. The use of marine-derived bacterial pigments displays a snowballing effect in recent times, being natural, environmentally safe, and health beneficial compounds. Although isolating marine bacteria is a strenuous task, these are still a compelling subject for researchers, due to their promising avenues for numerous applications. Marine-derived bacterial pigments serve as valuable products in the food, pharmaceutical, textile, and cosmetic industries due to their beneficial attributes, including anticancer, antimicrobial, antioxidant, and cytotoxic activities. Biodegradability and higher environmental compatibility further strengthen the use of marine bio-pigments over artificially acquired colored molecules. Besides that, hazardous effects associated with the consumption of synthetic colors further substantiated the use of marine dyes as color additives in industries as well. This review sheds light on marine bacterial sources of pigmented compounds along with their industrial applicability and therapeutic insights based on the data available in the literature. It also encompasses the need for introducing bacterial bio-pigments in global pigment industry, highlighting their future potential, aiming to contribute to the worldwide economy.

Abstract
A Gram-stain-negative, yellow-pigmented, non-spore-forming, non-motile, rod-shaped, catalase-positive, strictly aerobic bacterial strain, designated CAU 1491T, was isolated from seawater and its taxonomic position was examined using a polyphasic approach. Cells of strain CAU 1491T grew optimally at 30 °C, pH 7.5 and in 2.0 % (w/v) NaCl. Phylogenetic analysis based on the 16S rRNA gene sequence of CAU 1491T showed that it formed a distinct lineage within the family Flavobacteriaceae as a separate deep branch, with 97.0 % or lower sequence similarity to representatives of the genera Lacinutrix, Gaetbulibacter and Aquibacter. The major cellular fatty acids of strain CAU 1491T were iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 3-OH and summed feature 3. The polar lipid pattern consisted of diphosphatidylglycerol, phosphatidylserine, phosphatidylethanolamine and an unidentified phospholipid. The strain contained MK-6 as the sole respiratory quinone. Genome sequencing revealed that strain CAU 1491T has a genome size of 3.13 Mbp and a G+C content of 32.4 mol%. On the basis of the phenotypic, chemotaxonomic and genomic data, strain CAU 1491T represents a new genus and species in the family Flavobacteriaceae for which the name Pontimicrobium aquaticum gen. nov., sp. nov. is proposed. The type strain of Pontimicrobium aquaticum is CAU 1491T (=KCTC 72003T=NBRC 113695T).

Abstract
A bacterial strain CC-CTC003T was isolated from a synthetic wooden board. Cells of strain CC-CTC003T were Gram-stain-negative, rod-shaped, motile by gliding and formed yellow colonies. Optimal growth occurred at 25 °C, pH 7 and in the presence of 1 % NaCl. The phylogenetic analyses based on 16S rRNA genes revealed that strain CC-CTC003T belonged to the genus Flavobacterium and was most closely related to Flavobacterium cerinum (95.3 % sequence identity), Flavobacterium maris (94.9 % sequence identity), Flavobacterium qiangtangense (94.8 %) and Flavobacterium subsaxonicum (94.7 %) and had less than 94.7 % sequence similarity to other members of the genus. Average nucleotide identity (ANI) values between strain CC-CTC003T and the type strains of other closely related species were 70.1-74.1 %. The digital DNA-DNA hybridization (dDDH) with F. cerinum was 19.4 %. Strain CC-CTC003T contained C15 : 0, iso-C15 : 0, iso-C15 : 0 3-OH, iso-C17 : 0 3-OH, summed feature 3 (C16 : 1 ω6c / C16 : 1 ω7c) and summed feature 9 (C16 : 0 10-methyl / iso-C17 : 1 ω9c) as the predominant fatty acids. The polar lipid profile consisted of phosphatidylethanolamine, four uncharacterized aminophospholipids, two aminolipids and one unidentified glycolipid. The major polyamine was sym-homospermidine and contained MK-6 as major isoprenoid quinone. The DNA G+C content of the genomic DNA was 39.2 mol%. On the basis of the phylogenetic inference and phenotypic data, strain CC-CTC003T should be classified as a novel species, for which the name Flavobacterium supellecticarium sp. nov. is proposed. The type strain is CC-CTC003T (=BCRC 81146T=JCM 32838T).

Abstract
A novel Gram-stain-positive, aerobic, motile with peritrichous flagella, rod-shaped bacterium, designated CC-MHH1044T, was isolated from a preserved vegetable sample. A polyphasic taxonomic approach was applied to the isolates in order to clarify its taxonomic position. Growth of the strain CC-MHH1044T occurred at 15-50 °C (optimum, 30 °C), pH 6.0-8.0 (optimum, pH 7.0) and with 0-2.0 % (w/v) NaCl (optimum, 1 %, w/v). The genome of strain CC-MHH1044T consisted of 8.5 Mb and the genomic DNA G+C content was 58.5 mol%. Comparison of the 16S rRNA gene sequences showed that CC-MHH1044T belonged to the genus Cohnella and showed a close relationship with the type strains of Cohnella damuensis (96.2 %) and Cohnella panacarvi (95.9 %), and lower sequence similarity to other species. Average nucleotide identity values calculated from whole-genome sequencing data proved that CC-MHH1044T represents a distinct Cohnella species. The dominant cellular fatty acids (>5 %) included iso-C14 : 0(7.4 %), iso-C15 : 0 (6.4 %), anteiso-C15 : 0(40.3 %), C16 : 0 (6.6 %) and iso-C16 : 0 (27.0 %). The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, four unidentified aminophospholipids, one unidentified phospholipid and glycolipid. The major polyamine was spermidine. The predominant isoprenoid quinone was menaqinone 7 (MK-7). Based on its distinct phylogenetic, phenotypic and chemotaxonomic traits, together with results of comparative 16S rRNA gene sequence, average nucleotide identity and digital DNA-DNA hybridization analyses, we conclude that strain CC-MHH1044T represents a novel member of the genus Cohnella, for which the name Cohnella fermenti sp. nov. is proposed. The type strain is CC-MHH1044T (=BCRC 81147T=JCM 32834T).

Abstract
A polyphasic taxonomic approach was used to characterize a nitrogen-fixing bacterium, designated strain CC-HIH110T, isolated from paddy soil in Taiwan. Cells of strain CC-HIH110T were Gram-stain-negative, rod-shaped, motile with polar flagella, catalase-positive and oxidase-positive. Optimal growth occurred at 30 °С, pH 7 and 1 % NaCl. Phylogenetic analyses based on 16S rRNA genes revealed a distinct taxonomic position attained by strain CC-HIH110T associated with Rhizobium oryziradicis (98.4 % sequence identity), Allorhizobium vitis (97.8 %), Allorhizobium taibaishanense (97.7 %) and Allorhizobium undicola (96.0 %), and lower sequence similarity to other species. Average nucleotide identity (ANI) and digital DNA-DNA hybridization (dDDH) values between strain CC-HIH110T and the type strains of other closely related species were 71.5-88.6 % and 19.6-35.5 %, respectively. Strain CC-HIH110T contained C16 : 0 3-OH, C14 : 0 3-OH/iso C16 : 1 I and C18 : 1 ω7c/C18 : 1 ω6c as the predominant fatty acids. The polar lipid profile consisted of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylmonomethylethanolamine, phosphatidyldimethylethanolamine, phosphatidylcholine, three unknown aminophospholipids, two unknown phospholipids and an unknown lipid. The major polyamine was homospermidine. The DNA G+C content was 55.0 mol% and the predominant quinone was ubiquinone (Q-10). Based on its distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence, ANI and dDDH analyses, strain CC-HIH110T is proposed to represent a novel Allorhizobium species, for which the name Allorhizobium terrae sp. nov. (type strain CC-HIH110T=BCRC 80932T=JCM 31228T). In addition, Rhizobium oryziradicis is reclassified as Allorhizobium oryziradicis (type strain N19T=ACCC 19962T=KCTC 52413T) comb. nov.

Abstract
Microorganisms (bacteria, yeast, and microalgae) are a promising resource for products of high value such as nutrients, pigments, and enzymes. The majority of these compounds of interest remain inside the cell, thus making it necessary to extract and purify them before use. This review presents the challenges and opportunities in the production of these compounds, the microbial structure and the location of target compounds in the cells, the different procedures proposed for improving extraction of these compounds, and pulsed electric field (PEF)-assisted extraction as alternative to these procedures. PEF is a nonthermal technology that produces a precise action on the cytoplasmic membrane improving the selective release of intracellular compounds while avoiding undesirable consequences of heating on the characteristics and purity of the extracts. PEF pretreatment with low energetic requirements allows for high extraction yields. However, PEF parameters should be tailored to each microbial cell, according to their structure, size, and other factors affecting efficiency. Furthermore, the recent discovery of the triggering effect of enzymatic activity during cell incubation after electroporation opens up the possibility of new implementations of PEF for the recovery of compounds that are bounded or assembled in structures. Similarly, PEF parameters and suspension storage conditions need to be optimized to reach the desired effect. PEF can be applied in continuous flow and is adaptable to industrial equipment, making it feasible for scale-up to large processing capacities.

Abstract
Natural bioactive compounds with antioxidant activity play remarkable roles in the prevention of reactive oxygen species (ROS) formation. ROS, which are formed by different pathways, have various pathological influences such as DNA damage, carcinogenesis, and cellular degeneration. Incremental demands have prompted the search for newer and alternative resources of natural bioactive compounds with antioxidant properties. The marine environment encompasses almost three-quarters of our planet and is home to many eukaryotic and prokaryotic microorganisms. Because of extreme physical and chemical conditions, the marine environment is a rich source of chemical and biological diversity, and marine microorganisms have high potential as a source of commercially interesting compounds with various pharmaceutical, nutraceutical, and cosmeceutical applications. Bacteria and microalgae are the most important producers of valuable molecules including antioxidant enzymes (such as superoxide dismutase and catalase) and antioxidant substances (such as carotenoids, exopolysaccharides, and bioactive peptides) with various valuable biological properties and applications. Here, we review the current knowledge of these bioactive compounds while highlighting their antioxidant properties, production yield, health-related benefits, and potential applications in various biological and industrial fields.

Abstract
In this study, the shoreline of Lebanon, which extends over 225 km along the eastern side of the Mediterranean Sea, was characterized for its sediment microbial community diversity and composition using 16S rRNA gene sequencing with Illumina MiSeq technology. Non-metric multidimensional scaling (NMDS) analysis showed no clear grouping among nearby sampled sites along the shoreline. Insignificant diversion between the wet and dry season microbial communities was observed along the coast at each sampling site. A high variation at the genus level was observed, with several novel genera identified at high relative abundance in certain locations, such as JTB255 marine benthic groups OTU_4 (5.4%) and OTU_60 (3.2%), and BD7-8 marine group OTU_5 (2.9%).

Abstract
It is now recognized that host microbiome, the community of microorganisms that colonize the animal body (e.g. microbiota) and their genomes, play an important role in the health status of all organisms, from nutrient processing to protection from disease. In particular, the complex, bilateral interactions between the host innate immune system and the microbiota are crucial in maintaining whole body homeostasis. The development of nanotechnology is raising concern on the potential impact of nanoparticles-NPs on human and environmental health. Titanium dioxide-nTiO2, one of the most widely NP in use, has been shown to affect the gut microbiota of mammals and fish, as well as to potentially alter microbial communities. In the marine bivalve Mytilus galloprovincialis, nTiO2 has been previously shown to interact with hemolymph components, thus resulting in immunomodulation. However, no information is available on the possible impact of NPs on the microbiome of marine organisms. Bivalves host high microbial abundance and diversity, and alteration of their microbiota, in both tissues and hemolymph, in response to stressful conditions has been linked to a compromised health status and susceptibility to diseases. In this work, the effects of nTiO2 exposure (100 μg/L, 4 days) on Mytilus hemolymph microbiota were investigated by 16S rRNA gene-based profiling. Immune parameters were also evaluated. Although hemolymph microbiota of control and nTiO2-treated mussels revealed a similar core composition, nTiO2 exposure affected the abundance of different genera, with decreases in some (e.g. Shewanella, Kistimonas, Vibrio) and increases in others (e.g. Stenotrophomonas). The immunomodulatory effects of nTiO2 were confirmed by the increase in the bactericidal activity of whole hemolymph. These represent the first data on the effects of NPs on the microbiome of marine invertebrates, and suggest that the shift in hemolymph microbiome composition induced by nTiO2 may result from the interplay between the microbiota and the immune system.

Abstract
The order Sphingomonadales is a taxon of bacteria with a variety of physiological features and carotenoid pigments. Some of the coloured strains within this order are known to be aerobic anoxygenic phototrophs that contain characteristic photosynthesis gene clusters (PGCs). Previous work has shown that majority of the ORFs putatively involved in the biosynthesis of C40 carotenoids are located outside the PGCs in these strains. The main purpose of this study was to understand the genetic basis for the various colour/carotenoid phenotypes of the strains of Sphingomonadales. Comparative analyses of the genomes of 41 strains of this order revealed that there were different patterns of clustering of carotenoid biosynthesis (crt) ORFs, with four ORF clusters being the most common. The analyses also revealed that co-occurrence of crtY and crtI is an evolutionarily conserved feature in Sphingomonadales and other carotenogenic bacteria. The comparisons facilitated the categorisation of bacteria of this order into four groups based on the presence of different crt ORFs. Yellow coloured strains most likely accumulate nostoxanthin, and contain six ORFs (group I: crtE, crtB, crtI, crtY, crtZ, crtG). Orange coloured strains may produce adonixanthin, astaxanthin, canthaxanthin and erythroxanthin, and contain seven ORFs (group II: crtE, crtB, crtI, crtY, crtZ, crtG, crtW). Red coloured strains may accumulate astaxanthin, and contain six ORFs (group III: crtE, crtB, crtI, crtY, crtZ, crtW). Non-pigmented strains may contain a smaller subset of crt ORFs, and thus fail to produce any carotenoids (group IV). The functions of many of these ORFs remain to be characterised.

Abstract
In recent years, marine natural pigments have emerged as a powerful alternative in the various fields of food, cosmetic, and pharmaceutical industries because of their excellent biocompatibility, bioavailability, safety, and stability. Marine organisms are recognized as a rich source of natural pigments such as chlorophylls, carotenoids, and phycobiliproteins. Numerous studies have shown that marine natural pigments have considerable medicinal potential and promising applications in human health. In this review, we summarize the marine natural pigments as potential sources for therapeutic applications, including: antioxidant, anticancer, antiangiogenic, anti-obesity, anti-inflammatory activities, drug delivery, photothermal therapy (PTT), photodynamic therapy (PDT), photoacoustic imaging (PAI), and wound healing. Marine natural pigments will offer a better platform for future theranostic applications.

Abstract
A polyphasic taxonomic approach was used to characterize a presumably novel bacterium, designated strain CC-YTH191T, isolated from a fermented meal in Taiwan. Cells of strain CC-YTH191T were Gram-stain-negative aerobic rods, which grew at 15-40 °C (optimal 25-30 °C), pH 6.0-9.0 (optimal 7.0) and 1-2 % (w/v) NaCl (optimal 1 %). On the basis of 16S rRNA gene sequence analysis, strain CC-YTH191T appeared to belong to the genus Castellaniella, and was closely related to Castellaniella hirudinis (96.7 % similarity), Castellaniella ginsengisoli (96.7 %) and Castellaniella caeni (96.0 %), while with other related species it shared <96.0 % similarity. The major cellular fatty acids of the isolate were C16 : 0, C17 : 0cyclo, C14 : 0 3OH/C16 : 1iso I and C18 : 1ω7c/C18 : 1ω6c. The polar lipid profile contained diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine, phosphatidylserine, three unidentified phospholipids, an unidentified aminolipid and an unidentified aminophospholpid. Putrescine was the predominant polyamine followed by spermidine. The DNA G+C content was 62.2 mol% and the predominant quinone system was ubiquinone 8 (Q-8). All these features confirmed the placement of the strain CC-YTH191T as a novel species within the genus Castellaniella, for which the name Castellaniella fermenti sp. nov. is proposed. The type strain is CC-YTH191T (=BCRC 81023T=JCM 31755T).

Abstract
A Gram-stain-negative, aerobic, yellow-pigmented, flexirubin-producing, rod-shaped and endophytic bacterium, designated strain CC-YTH209T, was isolated from a maize leaf and subjected to a taxonomic study. Strain CC-YTH209T was found to grow at 15-40 °C (optimal 30 °C), at pH 6.0-8.0 (optimal pH 7.0) and in the presence of 0-2 % (optimal 1 %) (w/v) NaCl. On the basis of 16S rRNA gene sequence analysis, strain CC-YTH209T appeared to belong to the genus Chryseobacterium within the class Flavobacteriia, and was closely related to Chryseobacterium rigui CJ16T (97.5 % similarity) and Chryseobacterium taeanense PHA3-4T (96.9 %). The level of DNA-DNA relatedness between strain CC-YTH209T and Chryseobacterium rigui CJ16T was 14.4 % (reciprocal, 13.0 %). Phylogenetic analyses based on 16S rRNA genes revealed a distinct taxonomic position attained by strain CC-YTH209T within the clade that accommodated Chryseobacterium species. The DNA G+C content was 37.2 mol%. Strain CC-YTH209T contained menaquinone MK-6 as the predominant respiratory quinone and sym-homospermidine as the major polyamine. The major cellular fatty acids of the isolate were iso-C15 : 0, iso-C17 : 0 3-OH and C16 : 1ω6c/C16 : 1ω7c. The polar lipid profile comprised phosphatidylethanolamine and five aminolipids, three lipids, one glycolipid, one aminophospholipid and one phospholipid, which are presently uncharacterized. On the basis of evidence presented in this study, strain CC-YTH209T is considered to represent a novel species of the genus Chryseobacterium, for which the name Chryseobacterium endophyticum sp. nov. is proposed. The type strain is CC-YTH209T (=BCRC 80938T=JCM 31226T).

Abstract
A polyphasic approach was used to characterize an endospore-forming bacterium, designated strain CC-RT-ET, isolated from resin fragments. Strain CC-RT-ET was Gram-stain-variable and facultatively anaerobic, able to grow at 20-37 °C (optimal 30 °C) and pH6.0-9.0 (optimal pH 7.0). Ellipsoidal and terminal endospores were observed. The 16S rRNA gene sequence analysis of strain CC-RT-ET showed highest sequence similarity to Ammoniphilus oxalivorans RAOx-FST (97.8 %) and Ammoniphilus oxalaticus RAOx-1T (97.7 %). According to the DNA-DNA hybridization, the relatedness values of strain CC-RT-ET with Ammoniphilus oxalivorans RAOx-FST and Ammoniphilus oxalaticus RAOx-1T were 21 % and 29 %, respectively. The DNA G+C content was 39.2 mol% and the predominant quinone system was menaquinone-7 (MK-7). The major polar lipid profile consisted of diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and phosphatidylmethylethanolamine. The cell-wall peptidoglycan contained meso-diaminopimelic acid. The polyamine pattern showed predominance of sym-homospermidine and putrescine. The major fatty acids found in strain CC-RT-ET were C14 : 0, iso-C15 : 0, anteiso-C15 : 0 and C16 : 1ω7c/C16 : 1ω6c. Based on the distinct phylogenetic, phenotypic and chemotaxonomic traits together with results of comparative 16S rRNA gene sequence analysis, strain CC-RT-ET is considered to represent a novel species of the genus Ammoniphilus, for which the name Ammoniphilus resinaesp. nov. is proposed. The type strain is CC-RT-ET (=BCRC 80314T=DSM 24738T).

Abstract
Carotenoids are lipid-soluble pigments that are produced in some plants, algae, fungi, and bacterial species, which accounts for their orange and yellow hues. Carotenoids are powerful antioxidants thanks to their ability to quench singlet oxygen, to be oxidized, to be isomerized, and to scavenge free radicals, which plays a crucial role in the etiology of several diseases. Unusual marine environments are associated with a great chemical diversity, resulting in novel bioactive molecules. Thus, marine organisms may represent an important source of novel biologically active substances for the development of therapeutics. In this respect, various novel marine carotenoids have recently been isolated from marine organisms and displayed several utilizations as nutraceuticals and pharmaceuticals. Marine carotenoids (astaxanthin, fucoxanthin, β-carotene, lutein but also the rare siphonaxanthin, sioxanthin, and myxol) have recently shown antioxidant properties in reducing oxidative stress markers. This review aims to describe the role of marine carotenoids against oxidative stress and their potential applications in preventing and treating inflammatory diseases.

Abstract
A Gram-staining-negative, strictly aerobic, yellowish-orange, flexirubin-positive, rod-shaped, non-flagellated, non-spore-forming and non-gliding marine bacterium, designated strain CC-PY-50T, was isolated from estuarine water off Pingtung, Taiwan. The strain produced zeaxanthin as a major carotenoid pigment, and showed highest pairwise 16S rRNA gene sequence similarity to
Bizionia hallyeonensis
T-y7T (93.9 %) followed by
Corallibacter vietnamensis
KMM 6217T (93.8 %),
Geojedonia litorea
YCS-16T (93.7 %) and other members of the family
Flavobacteriaceae
(<93.7 %). Strain CC-PY-50T established a distinct phyletic lineage associated with
Mangrovimonas yunxiaonensis
LYYY01T (93.1 % sequence similarity) with poor bootstrap support during neighbour-joining and maximum-likelihood phylogenetic analyses (37 % for each). The polar lipid profile of strain CC-PY-50T was determined to accommodate large numbers of unknown lipids including major amounts of three unidentified aminolipids and two unidentified lipids, and moderate amounts of an unidentified phospholipid, an unidentified glycolipid and an unidentified lipid. In addition, phosphatidylethanolamine was also detected in significant amounts. The major (>5 % of total) fatty acids were iso-C15 : 0, iso-C15 : 1 G, iso-C17 : 0 3-OH, C16 : 0 and C16 : 1ω6c and/or C16 : 1ω7c. The DNA G+C content was 37.1 mol% and menaquinone-6 (MK-6) was the sole respiratory quinone. Based on the phylogenetic evidence and several distinguishing phenotypic and chemotaxonomic features, strain CC-PY-50T is proposed to represent a novel genus and species of the family
Flavobacteriaceae
, for which the name Hanstruepera neustonica gen. nov., sp. nov. is proposed. The type strain of the type species Hanstruepera neustonica gen. nov., sp. nov. is CC-PY-50T ( = JCM 19743T = BCRC 80747T). Emended descriptions of the species
Sediminibacter furfurosus
,
Mangrovimonas yunxiaonensis
,
Antarcticimonas flava
and
Hoppeia youngheungensis

Abstract
A Gram-stain-negative, aerobic, orange-pigmented, rod-shaped and non-motile bacterium, designated strain A6B8T, was isolated from seawater of the Mariana Trench. The isolate grew at 4–50 °C (optimum 30–35 °C), at pH 6.5–8.0 (optimum pH 7.5) and with 0.5–4.0 % (w/v) NaCl (optimum 1.0–2.0 %). Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain A6B8T was related most closely to the genus
Muriicola
and shared highest sequence similarity of 97.7 % with
Muriicola jejuensis
EM44T. Chemotaxonomic analysis showed menaquinone 6 (MK-6) was the predominant isoprenoid and iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH were the major cellular fatty acids. The polar lipid profile of strain A6B8T included phosphatidylethanolamine, three unidentified aminolipids and four unidentified lipids. The genomic DNA G+C content was 47.1 mol%. The DNA–DNA relatedness value (23.3 %) clearly demonstrated that strains A6B8T and
M. jejuensis
EM44T were representatives of two different species. Based on the phenotypic, phylogenetic and chemotaxonomic characterizations, A6B8T ( = CGMCC 1.12606T = KCTC 32436T) is considered to be the type strain of a novel species of the genus
Muriicola
, for which the name Muriicola marianensis sp. nov. is proposed.

Abstract
A Gram-stain-negative, strictly aerobic, rod- or oval-shaped, motile, non-spore-forming bacterium, designated strain CC-AMHB-3(T), was isolated from coastal surface seawater off Hualien, Taiwan. The novel strain showed high pairwise 16S rRNA gene sequence similarities to Ruegeria mobilis NBRC 101030(T) (96.5%), Ruegeria scottomollicae LMG 24367(T) (96.4%), Phaeobacter aquaemixtae SSK6-1(T) (96.2%), Phaeobacter daeponensis TF-218(T) (96.2%), Cribrihabitans marinus CZ-AM5(T) (96.1%) and other species of the family Rhodobacteraceae (≤ 95.9%). However, strain CC-AMHB-3(T) formed a distinct phyletic lineage associated with C. marinus CZ-AM5(T) during phylogenetic analyses. The polar lipid profile of strain CC-AMHB-3(T) included major amounts of diphosphatidylglycerol, phosphatidylglycerol and phosphatidylcholine; moderate amounts of phosphatidylethanolamine, an unidentified aminolipid, an unidentified phospholipid and an unidentified lipid; and trace amounts of an unidentified lipid and an unidentified phospholipid, which was qualitatively almost in line with that of C. marinus CZ-AM5(T) but remarkably distinct as compared with the type species of the genera Ruegeria (Ruegeria atlantica JCM 21234(T)) and Phaeobacter (Phaeobacter gallaeciensis JCM 21319(T)). In line with the fatty acid profile of C. marinus CZ-AM5(T), the major (>5% of total) fatty acids of strain CC-AMHB-3(T) were C(18:1)ω7c and/or C(18:1)ω6c (summed feature 8), 11-methyl C(18:1)ω7c and C(16:0). The DNA G+C content was 66.7 mol%. Ubiquinone-10 (Q-10) was the sole respiratory quinone. Thus, based on the results of the polyphasic study presented here, strain CC-AMHB-3(T) is considered to represent a novel species of the genus Cribrihabitans, for which the name Cribrihabitans neustonicus sp. nov. is proposed; the type strain is CC-AMHB-3(T) ( = JCM 19537(T) =BCRC 80695(T)). In addition, an emended description of the genus Cribrihabitans is also proposed.

The polar lipid profile included major amounts of diphosphatidylglycerol, phosphatidylglycerol, phosphatidylcholine, phosphatidylethanolamine and an unidentified aminolipid. In addition, moderate amounts of an unidentified lipid and trace amounts of an unidentified phospholipid were detected. The DNA G+C content was 67.9 mol%. Ubiquinone Q-10 was the sole respiratory quinone. Based on its phylogenetic distinctiveness and distinguishing phenotypic characteristics (in particular its polar lipid pattern), we conclude that strain CC-AMW-ET represents a novel genus and species of the family
Rhodobacteraceae
, for which the name Youngimonas vesicularis gen. nov., sp. nov. is proposed. The type strain of Youngimonas vesicularis is CC-AMW-ET ( = JCM 18819T = BCRC 80549T). In addition, an emended description of the genus
Donghicola
Yoon et al. 2007 and the reclassification of
Donghicola xiamenensis
Tan et al. 2009 as Pseudodonghicola xiamenensis gen. nov., comb. nov. (type strain Y-2T = MCCC 1A00107T = LMG 24574T = CGMCC 1.7081T) are proposed.

Abstract
Two Gram-staining-negative, aerobic, rod-shaped, non-spore-forming bacterial strains that are motile by a monopolar flagellum, designated CC-AMH-11(T) and CC-AMHZ-5, were isolated from droppings of a seashore bird off the coast of Hualien, Taiwan. The strains showed 99.7% mutual pairwise 16S rRNA gene sequence similarity, while exhibiting <96.2% sequence similarity to strains of other species of the genus Pseudomonas (95.7-95.9% similarity with type species, Pseudomonas aeruginosa LMG 1242T), and formed a distinct co-phyletic lineage in the phylogenetic trees. The common major fatty acids (>5% of the total) were C18 : 1ω7c and/or C18 : 1ω6c (summed feature 8), C16 : 1ω6c and/or C16 : 1ω7c (summed feature 3), C16 : 0 and C12 : 0. Phosphatidylethanolamine, phosphatidylglycerol, diphosphatidylglycerol, phosphatidylserine, an unidentified lipid and an unidentified phospholipid were detected as common polar lipids. The DNA G+C contents of strains CC-AMH-11(T) and CC-AMHZ-5 were 61.1 and 61.6 mol%, respectively. The common major respiratory quinone was ubiquinone 9 (Q-9), and the predominant polyamine was putrescine. The DNA-DNA hybridization obtained between the two strains was 79.0% (reciprocal value 89.4% using CC-AMHZ-5 DNA as the probe). The very high 16S rRNA gene sequence similarity and DNA-DNA relatedness and the poorly distinguishable phenotypic features witnessed between CC-AMH-11(T) and CC-AMHZ-5 suggested unambiguously that they are two distinct strains of a single genomic species. However, the strains also showed several genotypic and phenotypic characteristics that distinguished them from other closely related species of Pseudomonas. Thus, the strains are proposed to represent a novel species of Pseudomonas, for which the name Pseudomonas hussainii sp. nov. is proposed. The type strain is CC-AMH-11(T) ( = JCM 19513(T) = BCRC 80696(T)); a second strain of the same species is CC-AMHZ-5 ( = JCM 19512 = BCRC 80697). In addition, emended descriptions of the species Pseudomonas pohangensis, Pseudomonas benzenivorans and Pseudomonas segetis are also proposed.

Abstract
A Gram-stain negative, strictly aerobic, zeaxanthin-producing, rod-shaped, non-spore-forming bacterial strain which is motile by gliding, designated CC-AMWZ-3(T), was isolated from surface seawater off coastal Kending, Taiwan. Strain CC-AMWZ-3(T) was found to share 93.3 % and 96.0-92.4 % pairwise 16S rRNA gene sequence similarity to Gramella echinicola KMM 6050(T) and other Gramella species, respectively, and formed distinct phyletic lineage during phylogenetic analysis. The major fatty acids were identified as C16:0, iso-C15:0, anteiso-C15:0, C16:1 ω6c and/or C16:1 ω7c and iso-C17:1 ω9c and/or C16:0 10-methyl. Polar lipids were found to include phosphatidylethanolamine, six unidentified lipids and three unidentified aminolipids. The DNA G+C content was determined to be 40.6 mol%. Menaquinone-6 was the sole respiratory quinone identified and triamine-sym-homospermidine was the predominant polyamine. Based on the polyphasic characteristics that are in line with those of Gramella species, in addition to distinguishing phylogenetic and phenotypic features, strain CC-AMWZ-3(T) appears to represent a novel species of the genus Gramella, for which the name Gramella planctonica sp. nov. (type strain CC-AMWZ-3(T) = JCM 18807(T) = BCRC 80553(T)) is proposed. In addition, emended descriptions of the species Gramella aestuarii and Gramella echinicola are also proposed.
