A novel xylan-degrading bacterium, YT-1101T, was isolated from fresh water. The isolate was a Gram-reaction-negative, aerobic, motile, endospore-forming and rod-shaped bacterium. Phylogenetic analysis of the 16S rRNA gene sequence indicated that strain YT-1101T belonged to the genus Cohnella, sharing sequence similarities of less than 94 % with the type species. The genomic G+C content was 58.6 mol%. The predominant menaquinone was MK-7. The major fatty acids were anteiso-C15 : 0, iso-C16 : 0 and iso-C15 : 0. Major polar lipids were diphosphatidylglycerol, phosphatidylglycerol and phosphatidylethanolamine. On the basis of morphological, physiological and phylogenetic properties, strain YT-1101T represents a novel species of the genus Cohnella, for which the name Cohnella fontinalis sp. nov. is proposed. The type strain is YT-1101T (=NBRC 104957T =DSM 21753T).

The 16S Rrna Gene

A novel, non-pigmented, rod-shaped, Gram-negative strain was isolated from mesotrophic lake water in Zealand, Denmark. Phylogenetic analysis of the 16S rRNA gene sequence of the bacterium, designated strain 389T, indicated that the strain belonged to the genus Vogesella and formed a monophyletic group with Vogesella perlucida DS-28T (99.1 % nucleotide similarity); it was less related to Vogesella indigofera ATCC 19706T (96.9 % similarity) and Vogesella lacus LMG 24504T (96.8 % similarity). Hybridization of DNA from strain 389T and V. perlucida demonstrated a reassociation of 50.6±9.6 %. The DNA G+C content of strain 389T was 61.2 mol%. The fatty acid profile of the strain differed from those of the other strains representing the genus Vogesella by a high content of C16 : 1 ω7c and/or iso-C15 : 0 2-OH (71.6 %) and a lower content of C16 : 0. Strain 389T was capable of degrading peptidoglycan and had chitinase and lysozyme activities, possibly associated with the degradation of peptidoglycan, and had capacity for degradation of several other polymer compounds. Based on phenotypic and genotypic characteristics, strain 389T represents a novel species, for which we propose the name Vogesella mureinivorans sp. nov. The type strain is 389T (=DSM 21247T =LMG 25302T).

Sequence Similarities

In the early 1980s, a facultatively anaerobic, non-motile, short rod, designated 202T, was isolated from a chicken crop and identified as a homofermentative lactic acid bacterium. Phylogenetic analysis based on the 16S rRNA gene sequence revealed that the strain was affiliated with the genus Lactobacillus, clustering within the Lactobacillus acidophilus–delbrueckii group. In this analysis, strain 202T appeared to be most closely related to the type strains of Lactobacillus intestinalis and Lactobacillus amylolyticus, with gene sequence similarities of 96.1 and 96.2 %, respectively. Strain 202T was found to differ from these two species, however, when investigated by multilocus sequence analysis, and it also differed in terms of some of its metabolic properties. On the basis of these observations, strain 202T is considered to represent a novel species in the genus Lactobacillus, for which the name Lactobacillus gigeriorum sp. nov. is proposed; the type strain is 202T ( = CRBIP 24.85T = DSM 23908T).

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.

Two yellow-pigmented, Gram-negative, rod-shaped bacterial strains, GH1-10T and GH29-5T, were isolated from greenhouse soils in Korea. 16S rRNA gene sequence analysis indicated that these strains were related to members of the genus Flavobacterium. Strain GH1-10T was most closely related to Flavobacterium psychrolimnae and Flavobacterium denitrificans, with sequence similarities of 95.9 and 95.2 %, respectively. Strain GH29-5T was most closely related to ‘Flavobacterium saliodium’, F. denitrificans and Flavobacterium frigoris, with sequence similarities of 94.3, 92.5 and 92.5 %, respectively. The major cellular fatty acids of GH1-10T were iso-C15 : 0, summed feature 3 (iso-C15 : 0 2-OH and/or C16 : 1 ω7c) and iso-C17 : 0 3-OH, and those of GH29-5T were iso-C15 : 0, iso-C17 : 0 3-OH, iso-C15 : 1 G and iso-C15 : 0 3-OH. Both strains contained menaquinone with six isoprene units (MK-6) as the sole quinone. The DNA G+C contents of GH1-10T and GH29-5T were 35 and 39 mol%, respectively. Based on the phylogenetic and phenotypic data presented, it is concluded that the two bacteria represent two separate novel species of the genus Flavobacterium. The names proposed to accommodate these organisms are Flavobacterium daejeonense sp. nov., with type strain GH1-10T (=KACC 11422T=DSM 17708T), and Flavobacterium suncheonense sp. nov., with type strain GH29-5T (=KACC 11423T=DSM 17707T).
