Bacterium Strain

A novel Gram-staining-negative, rod-shaped, non-motile bacterium, strain AMV16T, was isolated from a soil sample collected from a mud volcano located in the Andaman Islands, India. The cell suspension was pale orange. Cells of strain AMV16T were positive for catalase, oxidase, lipase, ornithine decarboxylase and lysine decarboxylase and negative for gelatinase and urease. The fatty acids present were anteiso-C11 : 0 (5.4 %), anteiso-C12 : 0 (4.1 %), C12 : 0 (7.0 %), iso-C15 : 0 (14.4 %), anteiso-C15 : 0 (3.4 %), anteiso-C16 : 0 (3.0 %), C16 : 0 (2.6 %), anteiso-C17 : 0 (3.7 %), iso-C19 : 0 (9.7 %), C13 : 1 (13.8 %), iso-C15 : 1 G (15.9 %), iso-C16 : 1 G (11.1 %) and summed feature 5 (anteiso-C18 : 0 and/or C18 : 2ω6,9c; 5.9 %). Strain AMV16T contained MK-4 as the major respiratory quinone and diphosphatidylglycerol and phosphatidylethanolamine made up the phospholipids. The G+C content of DNA of strain AMV16T was 50.9 mol%. blast sequence similarity searches based on the 16S rRNA gene sequence indicated that species of the genus Marivirga were the nearest phylogenetic neighbours, with pairwise sequence similarity ranging from 89.9 to 90.0 %. Phylogenetic analyses indicated that strain AMV16T clustered with the type strains of Marivirga tractuosa and Marivirga sericea at a phylogenetic distance of 14.6 % (85.4 % similarity), distinct from clades representing other genera of the family ‘Flammeovirgaceae’. Based on the above-mentioned phenotypic and phylogenetic characteristics, strain AMV16T is proposed as a representative of a new genus and novel species, Cesiribacter andamanensis gen. nov., sp. nov.

A novel Gram-stain-positive, coccoid, non-motile bacterium, designated strain AMV4T, was isolated from a soil sample collected from a mud volcano located in the Andaman Islands, India. The colony was pale orange. Strain AMV4T was positive for oxidase, aesculinase, lysine decarboxylase and ornithine decarboxylase activities and negative for amylase, catalase, cellulase, protease, urease and lipase activities. 16S rRNA gene sequence analysis indicated that strain AMV4T was a member of the order Actinomycetales and was closely related to Aquipuribacter hungaricus with a sequence similarity of 97.13 % (pairwise alignment). Phylogenetic analyses showed that strain AMV4T clustered with Aquipuribacter hungaricus and was distantly related to the other genera of the family Intrasporangiaceae. DNA–DNA hybridization between strains AMV4T and Aquipuribacter hungaricus IV-75T showed a relatedness of 28 %. The predominant cellular fatty acids were iso-C15 : 0 (6.9 %), anteiso-C15 : 0 (25.3 %), C16 : 0 (12.9 %), anteiso-C16 : 0 (5.6 %), C18 : 1ω9c (19.8 %) and C18 : 3ω6,9,12c (9.1 %). The diagnostic diamino acid in the cell-wall peptidoglycan of strain AMV4T was meso-diaminopimelic acid. Strain AMV4T contained MK-10(H4) as the predominant respiratory quinone. The polar lipids consisted of phosphatidylglycerol, one unidentified glycolipid, two unidentified phospholipids and five unidentified lipids. The DNA G+C content of strain AMV4T was 74.3 mol%. Based on data from this taxonomic study using a polyphasic approach, it is proposed that strain AMV4T represents a novel species of the genus Aquipuribacter, with the suggested name Aquipuribacter nitratireducens sp. nov. The type strain is AMV4T ( = CCUG 58430T = DSM 22863T = NBRC 107137T).

In DNA–DNA hybridizations, DNA–DNA relatedness values of 99–100 % were recorded between the five novel strains. Lower DNA–DNA relatedness values (21–57 %) were recorded between strain 687B-08T and C. oncorhynchi 701B-08T, C. ureilyticum F-Fue-04IIIaaaaT and the type strains of other closely related, established species of the genus Chryseobacterium . The predominant respiratory quinone of strain 687B-08T was MK-6 and the major cellular fatty acids were iso-C15 : 0, iso-C17 : 1ω9c, iso-C17 : 0 3-OH and C16 : 1ω6c. The G+C content of the genomic DNA of strain 687B-08T was 38.6 mol%. Based on the phenotypic and genotypic evidence, the five novel strains isolated from rainbow trout represent a single, novel species of the genus Chryseobacterium , for which the name Chryseobacterium viscerum sp. nov. is proposed.
