Two Gram-stain-negative, rod-shaped, orange, catalase- and oxidase-positive, non-motile bacteria, designated W13M1AT and W15M10T, were isolated from the marine sponges Suberites carnosus and Leucosolenia sp., respectively, which were sampled from Lough Hyne, Co. Cork, Ireland. Analysis of the 16S rRNA gene sequences of these isolates revealed that they are members of the genus Maribacter, in the family Flavobacteriaceae of the phylum Bacteroidetes. The type strain most closely related to strain W13M1AT is Maribacter forsetii DSM 18668T with a gene sequence similarity of 96.5 %. The closest related type strain to strain W15M10T is Maribacter orientalis DSM 16471T with a gene sequence similarity of 98.3 %. Phylogenetic inference and phenotypic data combined indicate that the isolates represent two novel species of the genus Maribacter, for which the names Maribacter spongiicola sp. nov. with type strain W15M10T ( = NCIMB 14725T = DSM 25233T) and Maribacter vaceletii sp. nov. with type strain W13M1AT ( = NCIMB 14724T = DSM 25230T), are proposed.

Two bacterial strains, 5420S-12T and 5420S-16T, isolated from air samples, were characterized using a polyphasic approach. 16S rRNA gene sequence analysis showed that strain 5420S-12T was related phylogenetically to Microvirga subterranea FaiI4T (97.4 % sequence similarity) and Microvirga guangxiensis 25BT (97.1 %) and that strain 5420S-16T was closely related to Balneimonas flocculans TFBT (98.0 %) and Microvirga guangxiensis 25BT (97.2 %). The G+C content of the genomic DNA was 62.2 mol% for strain 5420S-12T and 61.5 mol% for strain 5420S-16T. The major fatty acid was C18 : 1 ω7c. The results of DNA–DNA hybridization and the phenotypic data showed that strains 5420S-12T and 5420S-16T could be distinguished from phylogenetically related species and represent two novel species within the genus Microvirga, for which the names Microvirga aerophila sp. nov. (type strain 5420S-12T =KACC 12743T =NBRC 106136T) and Microvirga aerilata sp. nov. (type strain 5420S-16T =KACC 12744T =NBRC 106137T) are proposed. Furthermore, the reclassification of Balneimonas flocculans as Microvirga flocculans comb. nov. (type strain TFBT =JCM 11936T =KCTC 12101T =IAM 15034T =ATCC BAA-817T) is proposed and an emended description of the genus Microvirga is provided.

A Gram-stain-positive, endospore-forming, rod-shaped bacterium, designated XJ259T, was isolated from a cold spring sample from Xinjiang Uyghur Autonomous Region, China. The isolate grew optimally at 20–30 °C and pH 7.3–7.8. Comparative analysis of the 16S rRNA gene sequence showed that isolate XJ259T belonged phylogenetically to the genus Paenibacillus, and was most closely related to Paenibacillus xinjiangensis B538T (with 96.6 % sequence similarity), Paenibacillus glycanilyticus DS-1T (96.3 %) and Paenibacillus castaneae Ch-32T (96.1 %), sharing less than 96.0 % sequence similarity with all other members of the genus Paenibacillus. Chemotaxonomic analysis revealing menaquinone-7 (MK-7) as the major isoprenoid quinone, diphosphatidylglycerol, phosphatidylethanolamine and two unknown phosphoglycolipids as the major cellular polar lipids, a DNA G+C content of 47.0 mol%, and anteiso-C15 : 0 and C16 : 0 as the major fatty acids supported affiliation of the new isolate to the genus Paenibacillus. Based on these data, isolate XJ259T is considered to represent a novel species of the genus Paenibacillus, for which the name Paenibacillus algorifonticola sp. nov. is proposed. The type strain is XJ259T ( = CGMCC 1.10223T  = JCM 16598T).

Emended Description

A polyphasic taxonomic study was performed on 22 thermotolerant, aerobic, endospore-forming bacteria from dairy environments. Seventeen isolates were retrieved from raw milk, one from a filter cloth and four from grass, straw or milking equipment. These latter four isolates (R-6546, R-7499, R-7764 and R-7440) were identified as Bacillus thermoamylovorans based on DNA–DNA hybridizations (values above 70 % with Bacillus thermoamylovorans LMG 18084T) but showed discrepancies in characteristics with the original species description, so an emended description of this species is given. According to 16S rRNA gene sequence analysis and DNA–DNA hybridization experiments, the remaining 18 isolates (R-6488T, R-28193, R-6491, R-6492, R-7336, R-33367, R-6486, R-6770, R-31288, R-28160, R-26358, R-7632, R-26955, R-26950, R-33520, R-6484, R-26954 and R-7165) represented one single species, most closely related to Bacillus thermoamylovorans (93.9 % 16S rRNA gene sequence similarity), for which the name Bacillus thermolactis is proposed. Cells were Gram-stain-positive, facultatively anaerobic, endospore-forming rods that grew optimally at 40–50 °C. The cell wall peptidoglycan type of strain R-6488T, the proposed type strain, was A1γ based on meso-diaminopimelic acid. Major fatty acids of the strains were C16 : 0 (28.0 %), iso-C16 : 0 (12.1 %) and iso-C15 : 0 (12.0 %). MK-7 was the predominant menaquinone, and major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and some unidentified phospholipids. DNA G+C content was 35.0 mol%. Phenotypic properties allowed discrimination from other thermotolerant species of the genus Bacillus and supported the description of the novel species Bacillus thermolactis, with strain R-6488T ( = LMG 25569T  = DSM 23332T) as the proposed type strain.

Three novel endophytic strains, designated 17B10-2-12T, 26C10-4-4 and D13-10-4-9, were isolated from the bark of Populus euramericana in Heze, Shandong Province, China. They were Gram-reaction-negative, aerobic, non-motile, short-rod-shaped, oxidase-positive and catalase-negative. A phylogenetic analysis of the 16S rRNA gene showed that the three novel strains clustered with members of the family Comamonadaceae and formed a distinct branch. The isolates shared 100 % similarities among themselves and had the highest sequence similarity with Xenophilus azovorans DSM 13620T (95.2 %) and Xenophilus arseniciresistens YW8T (95.0 %), and less than 95.0 % sequence similarities with members of other species. Their major fatty acids were C16 : 0, C17 : 0 cyclo, C18 : 1ω7c and C16 : 1ω7c/C16 : 1ω6c. The major polar lipids were diphosphatidylglycerol, phosphatidylglycerol, phosphatidylethanolamine and three unknown aminophospholipids. The predominant quinone was ubiquinone-8 (Q-8). The DNA G+C content was 69.5–70.0 mol%. Based on data from a polyphasic taxonomy study, the three strains represent a novel species of a novel genus of the family Comamonadaceae, for which the name Corticibacter populi gen. nov., sp. nov. is proposed. The type strain is 17B10-2-12T ( = CFCC 12099T = KCTC 42091T).

A Gram-negative, non-motile and rod-, oval- or coccoid-shaped bacterial strain, DSW-25T, which is phylogenetically closely related to the genera Staleya and Sulfitobacter, was isolated from seawater of the East Sea, Korea, and subjected to a polyphasic taxonomic study. Strain DSW-25T grew optimally at pH 7.0–8.0 and at 25 °C. It contained Q-10 as the predominant ubiquinone and C18 : 1 ω7c as the major fatty acid. Major polar lipids were phosphatidylcholine, phosphatidylglycerol, phosphatidylethanolamine and an unidentified phospholipid. The DNA G+C content was 56.9 mol%. Strain DSW-25T exhibited 16S rRNA gene sequence similarity values of 98.4 % to the type strain of Staleya guttiformis and of 96.6–97.6 % to Sulfitobacter species. There were no distinct phenotypic, particularly chemotaxonomic, properties to differentiate Staleya guttiformis and strain DSW-25T from the genus Sulfitobacter. DNA–DNA relatedness data and differential phenotypic properties, together with the phylogenetic distinctiveness, demonstrated that strain DSW-25T differs from recognized Sulfitobacter species and Staleya guttiformis. On the basis of phenotypic, chemotaxonomic, phylogenetic and genetic data, strain DSW-25T was classified in the genus Sulfitobacter as a member of a novel species, for which the name Sulfitobacter donghicola sp. nov. is proposed. The type strain is strain DSW-25T (=KCTC 12864T =JCM 14565T). It is also proposed that Staleya guttiformis be transferred to the genus Sulfitobacter as Sulfitobacter guttiformis comb. nov.

A novel brown-coloured, Gram-negative-staining, rod-shaped, motile, phototrophic, purple sulfur bacterium, designated strain AK40T, was isolated in pure culture from a sediment sample collected from Coringa mangrove forest, India. Strain AK40T contained bacteriochlorophyll a and carotenoids of the rhodopin series as major photosynthetic pigments. Strain AK40T was able to grow photoheterotrophically and could utilize a number of organic substrates. It was unable to grow photoautotrophically and did not utilize sulfide or thiosulfate as electron donors. Thiamine and riboflavin were required for growth. The dominant fatty acids were C12 : 0, C16 : 0, C18 : 1ω7c and summed feature 3 (C16 : 1ω7c and/or iso-C15 : 0 2-OH). The polar lipid profile of strain AK40T was found to contain diphosphatidylglycerol, phosphatidylethanolamine, phosphatidylglycerol and eight unidentified lipids. Q-10 was the predominant respiratory quinone. The DNA G+C content of strain AK40T was 65.5 mol%. 16S rRNA gene sequence comparisons indicated that the isolate represented a member of the family Chromatiaceae within the class Gammaproteobacteria. 16S rRNA gene sequence analysis indicated that strain AK40T was closely related to Phaeochromatium fluminis, with 95.2 % pairwise sequence similarity to the type strain; sequence similarity to strains of other species of the family was 90.8–94.8 %. Based on the sequence comparison data, strain AK40T was positioned distinctly outside the group formed by the genera Phaeochromatium, Marichromatium, Halochromatium, Thiohalocapsa, Rhabdochromatium and Thiorhodovibrio. Distinct morphological, physiological and genotypic differences from previously described taxa supported the classification of this isolate as a representative of a novel species in a new genus, for which the name Phaeobacterium nitratireducens gen. nov., sp. nov. is proposed. The type strain of Phaeobacterium nitratireducens is AK40T ( = JCM 19219T = MTCC 11824T).

A Gram-reaction-positive, rod-shaped, spore-forming bacterium, designated Gsoil 1105T, was isolated from soil of a ginseng field in Pocheon Province in South Korea and characterized in order to determine its taxonomic position. Comparative analysis of the 16S rRNA gene sequence showed that the isolate belongs to the order Bacillales, showing the highest level of sequence similarity with respect to Tumebacillus permanentifrigoris Eur1 9.5T (94.6 %). The phylogenetic distances from other described species with validly published names within the order Bacillales were greater than 9.0 %. Strain Gsoil 1105T had a genomic DNA G+C content of 55.6 mol% and menaquinone 7 (MK-7) as the major respiratory quinone. The major fatty acids were iso-C15 : 0 and anteiso-C15 : 0. On the basis of its phenotypic properties and phylogenetic distinctiveness, strain Gsoil 1105T represents a novel species of the genus Tumebacillus, for which the name Tumebacillus ginsengisoli sp. nov. is proposed. The type strain is Gsoil 1105T ( = KCTC 13942T  = DSM 18389T).

Two bacterial strains (SC-089T and SC-092T) isolated from sewage sludge compost were characterized by using a polyphasic approach. The isolates were Gram-negative short rods, catalase- and oxidase-positive, and showed good growth at 30 °C, at pH 7 and with 1 % (w/v) NaCl. Ubiquinone 8 was the major respiratory quinone, and phosphatidylethanolamine, phosphatidylglycerol and diphosphatidylglycerol were amongst the major polar lipids. On the basis of 16S rRNA gene sequence analysis, the strains were observed to be members of the family Alcaligenaceae, but could not be identified as members of any validly described genus. The low levels of 16S rRNA gene sequence similarity to other recognized taxa, together with comparative analysis of phenotypic traits and chemotaxonomic markers, supported the proposal of a new genus within the family Alcaligenaceae, for which the name Candidimonas gen. nov. is proposed. Strains SC-089T and SC-092T, which shared 99.1 % 16S rRNA gene sequence similarity, could be differentiated at the phenotypic level, and DNA–DNA hybridization results supported their identification as representing distinct species. The names proposed for these novel species are Candidimonas nitroreducens sp. nov. (type strain, SC-089T = LMG 24812T = CCUG 55806T) and Candidimonas humi sp. nov. (type strain, SC-092T = LMG 24813T = CCUG 55807T).

A Gram-negative, non-motile, aerobic bacterial strain, designated MJ20T, was isolated from farm soil near Daejeon (South Korea) and was characterized taxonomically by using a polyphasic approach. Comparative 16S rRNA gene sequence analysis showed that strain MJ20T belongs to the family Cytophagaceae, class Sphingobacteria, and was related most closely to Dyadobacter fermentans DSM 18053T (98.9 % sequence similarity), Dyadobacter beijingensis JCM 14200T (98.0 %) and Dyadobacter ginsengisoli KCTC 12589T (96.4 %). The G+C content of the genomic DNA of strain MJ20T was 48.5 mol%. The detection of MK-7 as the predominant menaquinone and a fatty acid profile with summed feature 4 (C16 : 1 ω7c and/or iso-C15 : 0 2-OH), iso-C15 : 0, C16 : 0 and C16 : 1 ω5c as major components supported the affiliation of strain MJ20T to the genus Dyadobacter. The new isolate exhibited relatively low levels of DNA–DNA relatedness with respect to D. fermentans DSM 18053T (mean±sd of three determinations, 47±7 %) and D. beijingensis JCM 14200T (38±8 %). On the basis of its phenotypic and genotypic properties together with phylogenetic distinctiveness, strain MJ20T (=KCTC 22481T =JCM 16232T) should be classified in the genus Dyadobacter as the type strain of a novel species, for which the name Dyadobacter soli sp. nov. is proposed.

A polyphasic study was undertaken to clarify the taxonomic position of Nonomuraea flexuosa DSM 41386T. The distinct 16S rRNA gene sequence phyletic branch formed by this strain was equated with nine related monophyletic clades composed of representatives of the genera classified in the family Streptosporangiaceae. The organism produced a PCR product characteristic of this taxon when examined using a set of oligonucleotide primers specific for members of the family Streptosporangiaceae. Strain DSM 41386T could also be distinguished from representatives of the nine genera assigned to this family using a combination of chemotaxonomic, morphological and physiological properties. It is evident from the genotypic and phenotypic data that strain DSM 41386T is misclassified in the genus Nonomuraea and merits recognition as a monospecific genus within the family Streptosporangiaceae. It is proposed that the name Thermopolyspora flexuosa gen. nov., comb. nov., nom. rev. be used for this purpose, with the type strain DSM 41386T (=NRRL B-24348T).
