Abstract
Two strains isolated from a sample of activated sludge that was obtained from a seawater-based wastewater treatment plant on the southeastern Mediterranean coast of Spain have been characterized to achieve their taxonomic classification, since preliminary data suggested they could represent novel taxa. Given the uniqueness of this habitat, as this sort of plants are rare in the world and this one used seawater to process an influent containing intermediate products from amoxicillin synthesis, we also explored their ecology and the annotations of their genomic sequences. Analysis of their 16S rRNA gene sequences revealed that one of them, which was orange-pigmented, was distantly related to
Vicingus serpentipes
(family
Vicingaceae
) and to other representatives of neighbouring families in the order
Flavobacteriales
(class
Flavobacteriia
) by 88–89 % similarities; while the other strain, which was yellow-pigmented, was a putative new species of
Lysobacter
(family
Xanthomonadaceae
, order
Xanthomonadales
, class
Gammaproteobacteria
) with
Lysobacter arseniciresistens
as closest relative (97.3 % 16S rRNA sequence similarity to its type strain). Following a polyphasic taxonomic approach, including a genome-based phylogenetic analysis and a thorough phenotypic characterization, we propose the following novel taxa: Parvicella tangerina gen. nov., sp. nov. (whose type strain is AS29M-1T=CECT 30217T=LMG 32344T), Parvicellaceae fam. nov. (whose type genus is Parvicella), and Lysobacter luteus sp. nov. (whose type strain is AS29MT=CECT 30171T=LMG 32343T).

Abstract
A polyphasic taxonomic study was conducted on three strains isolated from drinking water systems that had previously been deposited as Chryseobacterium species at the Spanish Type Culture Collection in order to complete their classification. Strains CECT 9293T, CECT 9390T and CECT 9393T were isolated from sites in Barcelona, Spain, in the framework of a project aimed at generating the first MALDI-TOF database specific for bacteria present in water for human consumption. Their partial 16S rRNA sequences showed that their closest relatives among the type strains of Chryseobacterium exhibited 98 % similarity or less, supporting their taxonomic novelty. At the same time, comparison between them revealed that strains CECT 9293T and CECT 9393T could perhaps be related at the species level as they shared 99.5 % similarity. However, whole genome sequencing was performed and the subsequent calculation of relatedness indices, average nucleotide identity and estimated DNA–DNA hybridization, ruled out that possibility and confirmed instead that each of the strains should be considered a separate species in the genus Chryseobacterium. Having clarified their status, we also performed phylogenomic analyses and searched for possible environmental or non-type material sequences that could be related to any of them at the species level. In parallel, the strains were characterized phenotypically and compared to their closest relatives to determine diagnostic traits to support their formal proposal. The proposed species are Chryseobacterium potabilaquae sp. nov. with the type strain CECT 9293T (=LMG 32084T), Chryseobacterium aquaeductus sp. nov. with the type strain CECT 9390T (=LMG 32085T) and Chryseobacterium fistulae sp. nov. with the type strain CECT 9393T (=LMG 32086T).

Abstract
According to the European Directives (UE) 2020/2184 and 2009/54/EC, which establishes the sanitary criteria for water intended for human consumption in Europe, water suitable for human consumption must be free of the bacterial indicators Escherichia coli, Clostridium perfringens and Enterococcus spp. Drinking water is also monitored for heterotrophic bacteria, which are not a human health risk, but can serve as an index of bacteriological water quality. Therefore, a rapid, accurate, and cost-effective method for the identification of these colonies would improve our understanding of the culturable bacteria of drinking water and facilitate the task of water management by treatment facilities. Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS) is potentially such a method, although most of the currently available mass spectral libraries have been developed in a clinical setting and have limited environmental applicability. In this work, a MALDI-TOF MS drinking water library (DWL) was defined and developed by targeting bacteria present in water intended for human consumption. This database, made up of 319 different bacterial strains, can contribute to the routine microbiological control of either treated drinking water or mineral bottled water carried out by water treatment and distribution operators, offering a faster identification rate compared to a clinical sample-based library. The DWL, made up of 96 bacterial genera, 44 of which are not represented in the MALDI-TOF MS bacterial Bruker Daltonics (BDAL) database, was found to significantly improve the identification of bacteria present in drinking water.

Abstract
A novel Gram-staining-negative, chemoorganotrophic, moderately halophilic, strictly aerobic bacterium, strain MED121T, was isolated from a seawater sample collected at the Blanes Bay Microbial Observatory in the north-western Mediterranean Sea. Analysis of its 16S rRNA gene sequence, retrieved from the whole-genome sequence, showed that this bacterium was most closely related to Marinomonas dokdonensis and other Marinomonas species (96.3 and 93.3-95.7 % sequence similarities, respectively), within the family Oceanospirillaceae. Strain MED121T was included into a whole-genome sequencing study and, subsequently, it was characterized using a polyphasic taxonomic approach. It was found to be oxidase and catalase positive, its cells are cocci to short rods, it does not ferment carbohydrates and does not reduce nitrate to nitrite or gas and it requires at least 2.5 % (w/v) marine salts and tolerates up to 7 % (w/v) salts. Its major cellular fatty acids in order of abundance are C16 : 1ω7c/C16 : 1ω6c, C18 : 1ω7c, C16 : 0 and C10 : 0 3-OH. Its genome had an approximate length of 5.1 million bases and a DNA G+C content equal to 40.9 mol%. Analysis of the annotated genes reveals the capacity for the synthesis of ubiquinone 8 (Q8) and the polar lipids phosphatidylglycerol and phosphatidylethanolamine, in agreement with other members of the genus. All the data collected supported the creation of a novel species to accommodate this bacterium, for which the name Marinomonas blandensis sp. nov. is proposed. The type strain is MED121T (=CECT 7076T=LMG 29722T).

Abstract
Strain 96-237T, a Gram-reaction-negative, curved- to spiral-shaped motile bacterium, isolated from coastal marine water, was found to be related to species of the genus Grimontia by 16S rRNA gene sequence comparison, sharing 98.3 % similarity to Grimontia marina CECT 8713Tand 98.8 % to 'Grimontiaindica' AK16. Phenotypic analysis revealed that strain 96-237T is slightly halophilic, mesophilic and facultatively anaerobic, fermenting d-glucose, d-ribose, d-mannose, d-mannitol, maltose and sucrose. It was positive for oxidase and indole production and negative for arginine dihydrolase and lysine and ornithine decarboxylases. Its major fatty acids were C16 : 1ω7c/C16 : 1ω6c (SF3), C18 : 1ω7c and C16 : 0. Its DNA G+C content was 48.4 mol%. The strain was different at the species level from all other species of the genusGrimontia, with average nucleotide identity indices of 79.6 % to Grimontia. hollisae CECT 8713T, 87.8 % to G. marina CECT 5069T and 89.1 % to 'G. indica' AK16 genomes. Thus, the strain represents a novel species for which we propose the name Grimontia celer and 96-237T (=CECT 9029T =KCTC 42960T =LMG 29238T) as the type strain.

Abstract
Two strains of Gram-stain-negative, chemo-organotrophic, aerobic and halophilic gammaproteobacteria, isolated from within the stem and roots of Spartina maritima in salt marshes from the south Atlantic Spanish coast, were found to represent a novel species in the genus Marinomonas through phylogenetic analysis of their 16S rRNA genes and phenotypic characterization. 16S rRNA gene sequences of the two strains shared < 96.2% similarity with other Marinomonas species, with Marimonas alcarazii being the most similar in sequence. They required sodium ions for growth, were able to thrive at low (4 °C) temperatures and at salinities of 12-15%, were unable to hydrolyse any tested macromolecule except casein, and grew with different monosaccharides, disaccharides, sugar alcohols, organic acids and amino acids. The novel species differed from other Marinomonas species in the use of several sole carbon sources, its temperature and salinity ranges for growth, ion requirements and cellular fatty acid composition, which included C16:0, C16:1 and C18:1 as major components and C10:0 3-OH, C12:0 and C12:0 3-OH as minor components. The name Marinomonas spartinae sp. nov. is proposed, with SMJ19T (=CECT 8886T=KCTC 42958T) as the type strain.

Abstract
Two strains of Gram-negative, facultatively anaerobic, slightly halophilic bacteria, isolated from healthy gilthead sea bream (Sparus aurata) cultured in Spanish Mediterranean fish farms, were different from their closest relatives, Vibrio scophthalmi and V. ichthyoenteri, by phenotypic, phylogenetic and genomic standards. The strains were negative for decarboxylase tests and lacked extracellular hydrolytic activities, but were able to ferment d-mannitol, sucrose, cellobiose and d-gluconate, among other carbohydrates. The major cellular fatty acids were C16:
1 and C16:
0, in agreement with other species of the genus Vibrio. Their 16S rRNA gene sequences were 98.4 and 97.2 % similar to those of the type strains of V. scophthalmi and V. ichthyoenteri, and the similarities using other housekeeping genes (ftsZ, rpoD, recA, mreB and gyrB) and indices of genomic resemblance (average nucleotide identity and estimated DNA–DNA hybridization) between the isolates and those type strains were clearly below intraspecific levels, supporting the recognition of the strains as members of a separate novel species. Thus, we propose the name Vibrio renipiscarius sp. nov., with DCR 1-4-2T ( = CECT 8603T = KCTC 42287T) as the type strain.

Abstract
Four strains (M15∅_3, M17(T), M49 and R37(T)) were isolated from Mediterranean seawater at Malvarrosa beach, Valencia, Spain. Together with an older preserved isolate (strain 2OM6) from cultured oysters at Vinaroz, Castellón, Spain, the strains were thoroughly characterized in a polyphasic study and were placed phylogenetically within the Roseobacter clade in the family Rhodobacteraceae. Highest 16S rRNA sequence similarities of the five strains to the types of any established species corresponded to Tropicibacter multivorans (95.8-96.4%), Phaeobacter inhibens (95.9-96.3%) and Phaeobacter gallaeciensis (95.9-96.2%). On the other hand, whole genome (ANI) and protein fingerprinting (MALDI-TOF) data proved: (i) non clonality among the strains, and (ii) the existence of two genospecies, one consisting of strains M15∅_3, M17(T), M49 and 2OM6 and another one consisting of strain R37(T). Phenotypic traits determined allow differentiating both genospecies from each other and from closely related taxa. In view of all data collected we propose to accommodate these isolates in two species as members of the genus Tropicibacter, Tropicibacter mediterraneus sp. nov. (type strain M17(T)=CECT 7615(T)=KCTC 23058(T)) and Tropicibacter litoreus sp. nov. (type strain R37(T)=CECT 7639(T)=KCTC 23353(T)).

Abstract
Strain R46T, a marine alphaproteobacterium, was isolated from Mediterranean seawater at Malvarrosa beach, Valencia, Spain. It is an aerobic chemo-organotrophic, mesophilic and slightly halophilic organism, with complex ionic requirements. Phylogenetic analyses based on the 16S rRNA and gyrB gene sequences showed that strain R46T formed a separate branch within the family
Rhodobacteraceae
, bearing similarities below 94.7 and 80.3 %, respectively, to any other recognized species. It contained Q10 as the predominant isoprenoid quinone and C18 : 1ω7c/C18 : 1ω6c as the major cellular fatty acid. Phosphatidylglycerol was the only identified polar lipid, although other lipids were also detected. The DNA G+C content of the genomic DNA was 61.3 mol%. On the basis of extensive phenotypic and phylogenetic comparative analysis, it is concluded that the strain represents a novel genus and species, for which the name Actibacterium mucosum gen. nov., sp. nov. is proposed. The type strain of the type species is Actibacterium mucosum R46T ( = CECT 7668T = KCTC 23349T).

Abstract
A novel actinomycete, designated PA3(T), was isolated from an oil refinery wastewater treatment plant, located in Palos de la Frontera, Huelva, Spain, and characterized taxonomically by using a polyphasic approach. Phylogenetic analysis based on 16S rRNA gene sequences showed that the isolate formed a distinct subclade in the Pseudonocardia tree together with Pseudonocardia asaccharolytica DSM 44247(T). The chemotaxonomic properties of the isolate, for example, the presence of MK-8 (H(4)) as the predominant menaquinone and iso-C(16:0) as the major fatty acid, are consistent with its classification in the genus Pseudonocardia. DNA:DNA pairing experiments between the isolate and the type strain of P. asaccharolytica DSM 44247(T) showed that they belonged to separate genomic species. The two strains were readily distinguished using a combination of phenotypic properties. Consequently, it is proposed that isolate PA3(T) represents a novel species for which the name Pseudonocardia hispaniensis sp. nov. is proposed. The type strain is PA3(T) (= CCM 8391(T) = CECT 8030(T)).

Abstract
Strains 2SM5T and 2SM6, two strictly aerobic chemo-organotrophic gammaproteobacteria, were isolated from Mediterranean seawater off the coast of Vinaroz, Castellón, Spain, in February, 1990. They were extensively characterized by a polyphasic study that placed them in the genus Pseudomonas. Phylogenetic analysis of 16S rRNA gene sequences showed that both strains shared 100 % sequence similarity and were closely related to members of the Pseudomonas pertucinogena clade, with less than 97.3 % similarity to strains of established species; Pseudomonas xiamenensis was the closest relative. Analysis of sequences of three housekeeping genes, rpoB, rpoD and gyrB, further confirmed the phylogenetic assignment of the Mediterranean isolates. Chemotaxonomic traits such as quinone and polar lipid composition also corroborated the placement of strains 2SM5T and 2SM6 in the gammaproteobacteria. Other phenotypic traits, including fatty acid composition, enabled clear differentiation of both isolates from other species of Pseudomonas. We therefore conclude that strains 2SM5T and 2SM6 represent a novel species of Pseudomonas, for which the name Pseudomonas litoralis is proposed; the type strain is 2SM5T ( = CECT 7670T = KCTC 23093T).

Abstract
A facultatively anaerobic marine gammaproteobacterium, designated strain M46T, was isolated from Mediterranean seawater at Malvarrosa beach, Valencia, Spain. The strain was characterized by using a polyphasic approach and was found to be situated within the genus Photobacterium in the family Vibrionaceae. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain M46T was closely related to P. rosenbergii CECT 7644T, P. halotolerans CECT 5860T and P. ganghwense CECT 7641T, showing sequence similarities of 96.8, 96.4 and 96.2 %, respectively. According to the results of phylogenetic analyses based on recA and gyrB gene sequences, the most closely related taxon was P. ganghwense CECT 7641T with 87.4 and 85.0 % sequence similarity, respectively. Regardless of the gene used in phylogenetic analysis, strain M46T always formed a separate and stable clade containing these three species of the genus Photobacterium. Strain M46T was not luminescent and produced a diffusible brown pigment. It required NaCl to grow, reduced nitrate to nitrite and oxidized a small number of substrates in Biolog GN plates. Strain M46T was positive for arginine dihydrolase (ADH), β-galactosidase, aesculin hydrolysis and DNase activity. In API ZYM tests, the novel strain was positive for alkaline phosphatase, leucine arylamidase and acidic phosphatase activities. The major cellular fatty acids were unsaturated C18 and C16, as in other members of the genus Photobacterium, but their relative amounts and the presence or absence of other fatty acids differentiated strain M46T from its closest relatives. Based on the results of this polyphasic taxonomic study, strain M46T represents a novel species of the genus Photobacterium, for which the name Photobacterium aphoticum is proposed. The type strain is M46T ( = CECT 7614T = KCTC 23057T).

Abstract
Strain MD5T, an aerobic marine alphaproteobacterium, was isolated from Mediterranean seawater at Malvarrosa beach, Valencia, Spain. The strain was characterized in a polyphasic study and was placed phylogenetically within the Roseobacter clade in the family Rhodobacteraceae. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain MD5T is related to Tropicibacter naphthalenivorans C02T, Phaeobacter inhibens T5T, P. gallaeciensis BS107T and P. daeponensis TF-218T, with 96.9, 96.2, 96.1 and 96.1 % sequence similarity, respectively. Phylogenetic analyses also showed that strain MD5T forms a stable clade only with T. naphthalenivorans C02T. Strain MD5T requires Na+ plus a divalent cation (either Mg2+ or Ca2+) to grow, does not reduce nitrate to nitrite and uses a large number of carbohydrates as sole carbon sources. It is positive for β-galactosidase and urease activities and aesculin hydrolysis. Enzyme activities displayed in the API ZYM strip were alkaline phosphatase, leucine arylamidase, acid phosphatase and α-glucosidase. Major cellular fatty acids were summed feature 8 (C18:1ω7c and/or C18:1ω6c; 70.9 %) and C16:0 (8.2 %). The results of physiological and biochemical tests allowed clear phenotypic differentiation of this isolate from the only described species of the genus Tropicibacter. It is evident from the genotypic and phenotypic data obtained that the strain should be classified in a novel species in the genus Tropicibacter. The name Tropicibacter multivorans sp. nov. is proposed, with the type strain MD5T (=CECT 7557T=KCTC 23350T).
