Abstract
The increasing rate of carbapenem-resistant bacteria within healthcare environments is an issue of great concern that needs urgent attention. This resistance is driven by metallo-β-lactamases (MBLs), which can catalyse the hydrolysis of almost all clinically available β-lactams and are resistant to all the clinically utilized β-lactamase inhibitors. In this study, an uncharacterized MBL is identified in a multidrug resistant isolate of the opportunistic pathogen, Chryseobacterium indologenes. Sequence analysis predicts this MBL (CIM-1) to be a lipoprotein with an atypical lipobox. Characterization of CIM-1 reveals it to be a high-affinity carbapenemase with a broad spectrum of activity that includes all cephalosporins and carbapenems. Results also shown that CIM-1 is potentially a membrane-associated MBL with an uncharacterized lipobox. Using prediction tools, we also identify more potentially lipidated MBLs with non-canonical lipoboxes highlighting the necessity of further investigation of lipidated MBLs.

Abstract
Five Hymenobacter strains isolated from air samples collected from the Suwon and Jeju regions of the Republic of Korea were studied using polyphasic taxonomic methods. Using 16S rRNA gene sequences and the resulting phylogenetic tree, the strains were primarily identified as members of the genus Hymenobacter. Digital DNA-DNA hybridization values and average nucleotide identities values for species delineation (70 and 95-96 %, respectively) between the five strains and their nearest type strains indicated that each strain represented a novel species. All strains were aerobic, Gram-stain-negative, mesophilic, rod-shaped and catalase- and oxidase-positive, with red to pink coloured colonies. The genome sizes of the five strains varied from 4.8 to 7.1 Mb and their G+C contents were between 54.1 and 59.4 mol%. Based on their phenotypic, chemotaxonomic and genotypic characteristics, we propose to classify these isolates into five novel species within the genus Hymenobacter for which we propose the names, Hymenobacter cellulosilyticus sp. nov., Hymenobacter cellulosivorans sp. nov., Hymenobacter aerilatus sp. nov., Hymenobacter sublimis sp. nov. and Hymenobacter volaticus sp. nov., with strains 5116 S-3T (=KACC 21925T=JCM 35216T), 5116 S-27T (=KACC 21926T=JCM 35217T), 5413 J-13T (=KACC 21928T=JCM 35219T), 5516 S-25T (=KACC 21931T=JCM 35222T) and 5420 S-77T (=KACC 21932T=JCM 35223T) as the type strains, respectively.

Abstract
A Gram-stain-negative, aerobic, reddish-coloured, rod-shaped and non-motile strain PAMC 29467T, was isolated from freshwater of the pond in Cambridge Bay, Canada. Strain PAMC 29467T was closely related to Hymenobacter yonginensis (98.1 % 16S rRNA gene similarity). Genomic relatedness analyses showed that strain PAMC 29467T is distinguishable from H. yonginensis based on average nucleotide identity (91.3 %) and digital DNA-DNA hybridization values (39.3 %). The major fatty acids (>10 %) of strain PAMC 29467T were summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c), C15 : 0 iso, C16 : 1 ω5c and summed feature 4 (C17 : 1 iso l and/or anteiso B). The major respiratory quinone was menaquinone-7. The genomic DNA G+C content was 61.5 mol%. Strain PAMC 29467T was separated from the type species in the genus Hymenobacter by its distinct phylogenetic position and some physiological characteristics. As a result, a novel species is proposed, with the name Hymenobacter canadensis sp. nov. (type strain, PAMC 29467T=KCTC 92787T=JCM 35843T).

Abstract
Gram-stain-negative, strictly aerobic, red-pink-coloured, rod-shaped and non-motile bacterial strains PAMC 29290, PAMC 29294T and PAMC 29296 were isolated from marine surface sediment sampled in the East Siberian Sea and strains PAMC 26553 and PAMC 26554T were obtained from an Antarctic lichen. Strains PAMC 29290, PAMC 29294T and PAMC 29296 were closely related to
Hymenobacter artigasi
(98.8 % 16S rRNA gene similarity),
Hymenobacter antarcticus
(97.3 %) and
Hymenobacter glaciei
(96.9 %), and PAMC 26553 and PAMC 26554T showed high similarity to
Hymenobacter ginsengisoli
(97.0 %),
Hymenobacter rivuli
(96.1 %) and
Hymenobacter setariae
(95.9 %). Genomic relatedness analyses showed that strains PAMC 29290, PAMC 29294T and PAMC 29296 could be distinguished from
H. artigasi
by average nucleotide identity (ANI; 93.1–93.2 %) and digital DNA–DNA hybridization (dDDH; 50.3–51.0 %) values. Strains PAMC 26553 and PAMC 26554T could be clearly distinguished from
H. ginsengisoli
with ANI values <79.8 % and dDDH values <23.3 %. The major fatty acids of strains PAMC 29290, PAMC 29294T and PAMC 29296 were C15 : 0 iso (21.0–26.0 %), summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c; 17.4–18.2 %), C15 : 0 anteiso (12.7–19.1 %) and summed feature 4 (C17 : 1 iso I and/or anteiso B; 8.6–16.1 %) and those of strains PAMC 26553 and PAMC 26554T were summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c; 20.7–22.2 %), C15 : 0 anteiso (17.5–19.7 %) and summed feature 4 (C17 : 1 iso I and/or anteiso B; 15.5–18.1 %). The major respiratory quinone was MK-7. The genomic DNA G+C contents were 60.6–60.8 mol%. The polar lipids of PAMC 29294T were found to consist of phosphatidylethanolamine, four unidentified aminolipids, an unidentified aminophospholipid and five unidentified lipids; those of PAMC 26554T were phosphatidylethanolamine, three unidentified aminolipids, four unidentified aminophospholipid and two unidentified lipids. The distinct phylogenetic position and some physiological characteristics distinguished the novel strains from closely related type strains in the genus
Hymenobacter
. Thus, two novel species are proposed, with the names Hymenobacter siberiensis sp. nov. (type strain, PAMC 29294T=KCTC 82466T=JCM 34574T) and Hymenobacter psoromatis sp. nov. (type strain, PAMC 26554T=KCTC 82464T=JCM 34572T), respectively.

Syst Appl Microbiol 2021; 44:126250. [PMID: 34592543 DOI: 10.1016/j.syapm.2021.126250] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/27/2021] [Revised: 09/02/2021] [Accepted: 09/03/2021] [Indexed: 10/20/2022]
Abstract
Seven Gram-negative, aerobic, non-sporulating, motile strains were isolated from terrestrial (R-67880T, R-67883, R-36501 and R-36677T) and aquatic (R-39604, R-39161T and R-39594T) East Antarctic environments (i.e. soil and aquatic microbial mats), between 2007 and 2014. Analysis of near-complete 16S rRNA gene sequences revealed that the strains potentially form a novel genus in the family Sphingomonadaceae (Alphaproteobacteria). DNA-DNA reassociation and average nucleotide identity values indicated distinction from close neighbors in the family Sphingomonadaceae and showed that the seven isolates form four different species. The main central pathways present in the strains are the glycolysis, tricarboxylic acid cycle and pentose phosphate pathway. The strains can use only a limited number of carbon sources and mainly depend on ammonia and sulfate as a nitrogen and sulfur source, respectively. The novel strains showed the potential of aerobic anoxygenic phototrophy, based on the presence of bacteriochlorophyll a pigments, which was corroborated by the presence of genes for all building blocks for a type 2 photosynthetic reaction center in the annotated genomes. Based on the results of phenotypic, genomic, phylogenetic and chemotaxonomic analyses, the strains could be assigned four new species in the novel genus Chioneia gen. nov. in the family Sphingomonadaceae, for which the names C. frigida sp. nov. (R-67880T, R-67883 and R-36501), C. hiemis sp. nov. (R-36677T), C. brumae sp. nov. (R-39161T and R-39604) and C. algoris sp. nov. (R-39594T) are proposed.

Abstract
Three Gram-stain-negative, aerobic, circular, convex, red-colored and rod-shaped bacterial strains, designated BT439T, BT662T and BT683T were obtained from soil collected in South Korea. The phylogenetic analysis based on 16S rRNA gene sequences of the strains revealed a distinct lineage within the genus Hymenobacter. The complete genome sequence of strains BT439T, BT662T and BT683T is 5,542,738 bp, 5,964,541 bp, and 5,192,601 bp size, respectively. All three strains were found to have MK-7 as the major respiratory quinone. The major polar lipids of strains BT439T and BT662T were identified as phosphatidylethanolamine, aminophospholipids and amino lipids. Strain BT683T contained phosphatidylethanolamine. The major cellular fatty acids of strain BT439T were iso-C15:0, summed feature 3 (C16:1 ω6c/C16:1 ω7c) and anteiso-C15:0; strain BT662T possessed iso-C15:0 and summed feature 3 (C16:1 ω6c/C16:1 ω7c); strain BT683T were summed feature 3 (C16:1 ω6c/C16:1 ω7c), C16:1 ω5c, iso-C15:0 and anteiso-C15:0. Based on the polyphasic analysis, strains BT439T, BT662T and BT683T can be suggested as three novel bacterial species within the genus Hymenobacter and the proposed names are Hymenobacter properus sp. nov., Hymenobacter ruricola sp. nov. and Hymenobacter jeongseonensis sp. nov., respectively. The type strain of Hymenobacter properus is BT439T (= KCTC 72900T = NBRC 114849T), Hymenobacter ruricola is BT662T (= KACC 21966T = NBRC 114855T) and the type strain of Hymenobacter jeongseonensis is BT683T (= KACC 22013T = NBRC xxxxxT).

Abstract
Between 2014 and 2016, 16 Gram-stain-negative, aerobic, rod-shaped and yellow-orange pigmented bacteria were isolated from exposed soils from the Utsteinen region, Sør Rondane Mountains, East Antarctica. Analysis of their 16S rRNA gene sequences revealed that the strains form a separate cluster in the genus Spirosoma, with Spirosoma rigui KCTC 12531T as its closest neighbour (97.8 % sequence similarity). Comparative genome analysis of two representative strains (i.e. R-68523T and R-68079) of the new group with the type strains of Spirosoma rigui (its closest neighbour) and Spirosoma linguale (type species of the genus), yielded average nucleotide identity values of 73.9-78.7 %. Digital DNA-DNA reassociation values of the two strains and these type strains ranged from 20.3 to 22.0 %. The predominant cellular fatty acids of the two novel strains were summed feature 3 (i.e. C16 : 1 ω7c and/or iso-C15 2-OH), C16 : 1 ω5c, C16 : 0 and iso-C15 : 0. The new Spirosoma strains grew with 0-0.5 % (w/v) NaCl, at pH 6.5-8.0 and displayed optimum growth between 15 and 25 °C. Based on the results of phenotypic, genomic, phylogenetic and chemotaxonomic analyses, the new strains represent a novel species of the genus Spirosoma for which the name Spirosoma utsteinense sp. nov. is proposed. The type strain is R-68523T (=LMG 31447T=CECT 9925T).

Abstract
Two bacterial strains designated as MA3T and BT182 were isolated from a soil sample in South Korea. Cells of the two strains were Gram-stain-negative, non-motile, rod-shaped and formed red colonies on R2A agar at 25 °C. The 16S rRNA genes of the two strains shared a sequence similarity of 99.8%. Both strains shared the highest 16S rRNA gene similarity of 96.8% with Hymenobacter edaphi NLT, followed by Hymenobacter paludis KBP-30T (96.3%), Hymenobacter coalescens WW84T (96.3%) and Hymenobacter gummosus ANT-18T (96.3%). Growth was observed at 15-37 °C (optimum 30 °C), pH 6-8 (optimum pH 7) and in the presence up to 1% NaCl. The genome size of strains MA3T and BT182 is 4.9 Mb and 4.8 Mb, respectively. The genomic G + C content of both strains is 62.0 mol%. The main polar lipid of the strains was phosphatidylethanolamine, the only respiratory quinone detected was menaquinone-7 and the major fatty acids were anteiso-C15:0, iso-C15:0, summed feature 4 (iso-C17:1 I/anteiso-C17:1 B) and summed feature 3 (C16:1 ω6c/C16:1 ω7c), supporting the affiliation of these strains with the genus Hymenobacter. Based on the phylogenetic, genotypic, phenotypic and chemotaxonomic data, strains MA3T and BT182 represent a novel species of the genus Hymenobacter, for which the name Hymenobacter busanensis is proposed. The type strain is MA3T (= KCTC 72631T = NBRC 114193T).

Abstract
Four Gram-negative, aerobic, rod-shaped and yellow-orange pigmented bacteria (R-46770, R-48165T, R-50232 and R-50233) were isolated from intertidal sediment and water of the Westerschelde estuary between 2006 and 2012. Analysis of their 16S rRNA gene sequences revealed that the four strains form a separate cluster between validly described type strains of the genus Leeuwenhoekiella. DNA-DNA reassociation values of two representative strains (i.e. R-48165T and R-50232) of the new group with type strains of Leeuwenhoekiella species ranged from 18.7 to 56.6 %. A comparative genome analysis of the two strains and the type strains confirmed average nucleotide identity values from 75.6 to 94.4 %. The G+C contents of the genomic DNA of strains R-48165T and R-50232 were 37.80 and 37.83 mol%, respectively. The predominant cellular fatty acids of the four novel strains were summed feature 3 (i.e. C16 : 1ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, iso-C15 : 1 G and iso-C17 : 0 3-OH. The four new Leeuwenhoekiella-like strains grew with 0.5-12 % (w/v) NaCl, at pH 5.5-9.0 and displayed optimum growth between 20 and 30 °C. Based on the results of phenotypic, genomic, phylogenetic and chemotaxonomic analyses, the four new strains represent a novel species of the genus Leeuwenhoekiella for which the name Leeuwenhoekiella aestuarii sp. nov. is proposed. The type strain is LMG 30908T (=R-48165T=CECT 9775T=DSM 107866T). Genome analysis of type strains of the genus Leeuwenhoekiella revealed a large number of glycosyl hydrolases, peptidases and carboxyl esterases per Mb, whereas the number of transporters per Mb was low compared to other bacteria. This confirmed the environmental role of Leeuwenhoekiella species as (bio)polymer degraders, with a specialization on degrading proteins and high molecular weight compounds. Additionally, the presence of a large number of genes involved in gliding motility and surface adhesion, and large numbers of glycosyl transferases per Mb confirmed the importance of these features for Leeuwenhoekiella species.

Biological Ice-Nucleating Particles Deposited Year-Round in Subtropical Precipitation. Appl Environ Microbiol 2019; 85:AEM.01567-19. [PMID: 31562166 DOI: 10.1128/aem.01567-19] [Citation(s) in RCA: 13] [Impact Index Per Article: 2.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2019] [Accepted: 09/17/2019] [Indexed: 11/20/2022] Open
Abstract
Airborne bacteria that nucleate ice at relatively warm temperatures (>-10°C) can interact with cloud water droplets, affecting the formation of ice in clouds and the residency time of the cells in the atmosphere. We sampled 65 precipitation events in southeastern Louisiana over 2 years to examine the effect of season, meteorological conditions, storm type, and ecoregion source on the concentration and type of ice-nucleating particles (INPs) deposited. INPs sensitive to heat treatment were inferred to be biological in origin, and the highest concentrations of biological INPs (∼16,000 INPs liter-1 active at ≥-10°C) were observed in snow and sleet samples from wintertime nimbostratus clouds with cloud top temperatures as warm as -7°C. Statistical analysis revealed three temperature classes of biological INPs (INPs active from -5 to -10°C, -11 to -12°C, and -13 to -14°C) and one temperature class of INPs that were sensitive to lysozyme (i.e., bacterial INPs, active from -5 to -10°C). Significant correlations between the INP data and abundances of taxa in the Bacteroidetes, Firmicutes, and unclassified bacterial divisions implied that certain members of these phyla may possess the ice nucleation phenotype. The interrelation between the INP classes and fluorescent dissolved organic matter, major ion concentrations (Na+, Cl-, SO4 2-, and NO3 -), and backward air mass trajectories indicated that the highest concentrations of INPs were sourced from high-latitude North American and Asian continental environments, whereas the lowest values were observed when air was sourced from marine ecoregions. The intra- and extracontinental regions identified as sources of biological INPs in precipitation deposited in the southeastern United States suggests that these bioaerosols can disperse and affect meteorological conditions thousands of kilometers from their terrestrial points of origin.IMPORTANCE The particles most effective at inducing the freezing of water in the atmosphere are microbiological in origin; however, information on the species harboring this phenotype, their environmental distribution, and ecological sources are very limited. Analysis of precipitation collected over 2 years in Louisiana showed that INPs active at the warmest temperatures were sourced from terrestrial ecosystems and displayed behaviors that implicated specific bacterial taxa as the source of the ice nucleation activity. The abundance of biological INPs was highest in precipitation from winter storms and implied that their in-cloud concentrations were sufficient to affect the formation of ice and precipitation in nimbostratus clouds.

[PMID: 30619134 PMCID: PMC6297676 DOI: 10.3389/fmicb.2018.03043] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/12/2018] [Accepted: 11/26/2018] [Indexed: 11/13/2022] Open
Abstract
Solar panels can be found practically all over the world and represent a standard surface that can be colonized by microbial communities that are resistant to harsh environmental conditions, including high irradiation, temperature fluctuations and desiccation. These properties make them not only ideal sources of stress-resistant bacteria, but also standard devices to study the microbial communities and their colonization process from different areas of Earth. We report here a comprehensive description of the microbial communities associated with solar panels in Berkeley, CA, United States. Cultivable bacteria were isolated to characterize their adhesive capabilities, and UV- and desiccation-resistance properties. Furthermore, a parallel culture-independent metagenomic and metabolomic approach has allowed us to gain insight on the taxonomic and functional nature of these communities. Metagenomic analysis was performed using the Illumina HiSeq2500 sequencing platform, revealing that the bacterial population of the Berkeley solar panels is composed mainly of Actinobacteria, Bacteroidetes and Proteobacteria, as well as lower amounts of Deinococcus-Thermus and Firmicutes. Furthermore, a clear predominance of Hymenobacter sp. was also observed. A functional analysis revealed that pathways involved in the persistence of microbes on solar panels (i.e., stress response, capsule development, and metabolite repair) and genes assigned to carotenoid biosynthesis were common to all metagenomes. On the other hand, genes involved in photosynthetic pathways and general autotrophic subsystems were rare, suggesting that these pathways are not critical for persistence on solar panels. Metabolomics was performed using a liquid chromatography tandem mass spectrometry (LC-MS/MS) approach. When comparing the metabolome of the solar panels from Berkeley and from Valencia (Spain), a very similar composition in polar metabolites could be observed, although some metabolites appeared to be differentially represented (for example, trigonelline, pantolactone and 5-valerolactone were more abundant in the samples from Valencia than in the ones from Berkeley). Furthermore, triglyceride metabolites were highly abundant in all the solar panel samples, and both locations displayed similar profiles. The comparison of the taxonomic profile of the Californian solar panels with those previously described in Spain revealed striking similarities, highlighting the central role of both selective pressures and the ubiquity of microbial populations in the colonization and establishment of microbial communities.

Abstract
Strain S12-2-1T was isolated from a soil sample collected in the Gyeongsangnam-do province of the Republic of Korea. The isolate is a Gram-stain-negative, aerobic, short, rod-shaped bacterium, and its colonies are red to pink in colour. Analysis of the 16S rRNA gene identified strain S12-2-1T as a member of the genus Hymenobacter in the family Cytophagaceae, with high levels of 16S rRNA gene sequence similarity to Hymenobacter arizonensis OR362-8T (97.7 %), Hymenobacter sedentarius DG5BT (97.4 %) and Hymenobacter humi DG31AT (97.2 %). The isolate was positive for catalase and oxidase, but negative for acid production from glucose. The growth of strain S12-2-1T was supported at 4-30 °C, pH 7-10 and in the presence of 0-0.5 % NaCl. Strain S12-2-1T contained menaquinone-7 as the predominant respiratory quinone, sym-homospermidine as the major polyamine and iso-C15 : 0, anteiso-C15 : 0 and summed feature 3 (C16 : 1ω7c/C16 : 1ω6c) as the major fatty acids. Phosphatidylethanolamine was the major polar lipid. The genomic DNA G+C content was 58.7 mol%. Phenotypic and chemotaxonomic data supported the assignment of the isolate to the genus Hymenobacter. However, strain S12-2-1T exhibited a relatively low level of DNA-DNA relatedness with H. humi (31.7 %), H. arizonensis (24.4 %) and H. sedentarius (21.3 %). Based on its phenotypic and genotypic properties, along with its phylogenetic distinctiveness, strain S12-2-1T should be considered a novel species in the genus Hymenobacter, for which the name Hymenobacter pedocola sp. nov. is proposed. The type strain is S12-2-1T (=KCTC 52730T=JCM 32198T).

Abstract
The purpose of this announcement is to effect the valid publication of the following effectively published new names and new combinations under the procedure described in the Bacteriological Code (1990 Revision). Authors and other individuals wishing to have new names and/or combinations included in future lists should send an electronic copy of the published paper to the IJSEM Editorial Office for confirmation that all of the other requirements for valid publication have been met. It is also a requirement of IJSEM and the ICSP that authors of new species, new subspecies and new combinations provide evidence that types are deposited in two recognized culture collections in two different countries. It should be noted that the date of valid publication of these new names and combinations is the date of publication of this list, not the date of the original publication of the names and combinations. The authors of the new names and combinations are as given below. Inclusion of a name on these lists validates the publication of the name and thereby makes it available in the nomenclature of prokaryotes. The inclusion of a name on this list is not to be construed as taxonomic acceptance of the taxon to which the name is applied. Indeed, some of these names may, in time, be shown to be synonyms, or the organisms may be transferred to another genus, thus necessitating the creation of a new combination.

Abstract
A Gram-stain-negative, non-spore-forming, short rod-shaped, non-motile, light-pink bacterial strain, MIMtkLc17T, was isolated from biological soil crusts collected in Liangcheng, Inner Mongolia. Growth of strain MIMtkLc17T was observed at 2–35 °C and in the presence of 1% (w/v) NaCl. Phylogenetic analysis of 16S rRNA gene sequences showed that sequence similarities between strain MIMtkLc17T and the type strains of species of the genus Hymenobacter ranged from 89.93% to 96.49%. Strain MIMtkLc17T can secrete mass polysaccharide. The major fatty acids of strain MIMtkLc17T were iso-C15 : 0, summed feature 3 (C16 : 1ω7c/C16 : 1ω6c), C16 : 1ω5c and summed feature 4 (iso-C17 : 1 I/anteiso-C17 : 1 B). The sole respiratory quinone was menaquinone MK-7. The G+C content of the chromosomal DNA was 57.8 mol%. The results of phylogenetic, chemotaxonomic and phenotypic characterization indicated that strain MIMtkLc17T can be distinguished from all known species of the genus Hymenobacter and represents a novel species of this genus, for which the name Hymenobacter terrenus sp. nov. is proposed. The type strain is MIMtkLc17T ( = MCCC 1K00507T = KCTC 42636T).

Abstract
A novel Gram-stain-negative, non-motile, rod-shaped and watermelon-red-pigmented aerobic bacterial strain, designated YIM 77969T, was isolated from a soil sample of Jiuxiang cave, a tourism cave located in Yiliang county, Yunnan province, south-west China. Phylogenetic analysis based on the 16S rRNA gene sequence indicated that strain YIM 77969T belongs to the genus Hymenobacter, and was closely related to Hymenobacter tibetensis XTM003T (96.58 %), Hymenobacter gelipurpurascens Txg1T (96.02 %) and Hymenobacter xinjiangensis X2-1gT (95.80 %). Growth of strain YIM 77969T occurred at 5-35 °C, at pH 5.0-9.0 and in the presence of 0-1 % (w/v) NaCl. The predominant menaquinone was MK-7. The major fatty acids were iso-C15 : 0, C16 : 1ω5c and summed feature 3 (C16 : 1ω7c and/or C16 : 1ω6c). The polar lipid profiles consisted of the major compound phosphatidylethanolamine, two unknown aminolipids, three unknown aminophospholipids, one glycolipid and one unknown polar lipid. Pigment analysis showed that the pigment belonged to the plectaniaxanthin series of carotenoid pigments. The genomic DNA G+C content was 55.2 mol%. On the basis of phylogenetic, phenotypic and chemotaxonomic characteristics, strain YIM 77969T is considered to represent a novel species of the genus Hymenobacter, for which the name Hymenobacter mucosus sp. nov. is proposed. The type strain is YIM 77969T ( = KCTC 32567T = DSM 28041T).
