Brevibacterium siliguriense sp. nov., a facultatively oligotrophic bacterium isolated from river water

Résumé

A Gram-positive-staining, rod-shaped, facultatively oligotrophic bacterial strain, designated MB18 T , was isolated from a water sample collected from the River Mahananda at Siliguri (26° 44′ 23.20′ N, 88° 25′ 22.89′ E), West-Bengal, India. On the basis of 16S rRNA gene sequence similarity, the closest relative of this strain was Brevibacterium epidermidis NCDO 2286 T (96 % similarity). The DNA G+C content of strain MB18 T was 64.6 mol%. Chemotaxonomic data [MK-8(H 2 ) as the major menaquinone, galactose as the sole cell-wall sugar, meso -diaminopimelic acid as the diagnostic cell-wall diamino acid, phosphatidylglycerol and diphosphatidylglycerol as constituents of the polar lipids, anteiso-C 15 : 0 , anteiso-C 17 : 0 and iso-C 15 : 0 as the major fatty acids] supported the affiliation of strain MB18 T to the genus Brevibacterium . The results of DNA G+C content, 16S rRNA gene sequence analysis and biochemical and physiological analyses allowed genotypic and phenotypic differentiation of strain MB18 T from its nearest neighbour B. epidermidis . The isolate therefore represents a novel species, for which the name Brevibacterium siliguriense sp. nov. is proposed; the type strain is MB18 T ( = DSM 23676 T = LMG 25772 T ).
