Abstract

A facultatively anaerobic, endospore forming, alkali-tolerant, Gram-stain-positive, motile, rod-shaped bacterium, designated strain AK61, was isolated from a sediment sample collected from Coringa mangrove forest, India. Colonies were circular, 1.5 mm in diameter, shiny, smooth, yellowish and convex with entire margins after 48 h growth at 30 °C. Growth occurred at 15–42 °C, with 0–3 % (w/v) NaCl and at pH 6–9. AK61 was positive for amylase activity and negative for oxidase, catalase, aesculinase, caseinase, cellulase, DNase, gelatinase, lipase and urease activities. The fatty acids were dominated by branched types with iso- and anteiso- saturated fatty acids with a high abundance of iso-C, iso-C, anteiso-C and iso-C; the cell-wall peptidoglycan contained -diaminopimelic acid as the diagnostic diamino acid; and MK-7 was the major menaquinone. DNA–DNA hybridization between AK61 and MTCC 4374 and between AK61 and KCTC 3880 showed relatedness of 37.99 and 33.32 % respectively. The DNA G+C content of AK61 was 44 mol%. The results of a sequence similarity search based on 16S rRNA gene sequences indicated that and were the nearest phylogenetic neighbours, with a pair-wise sequence similarity of 97.69 and 97.55 % respectively. The results of phylogenetic analysis indicated that AK61 was clustered with and . On the basis of its phenotypic characteristics and phylogenetic inference, AK61 represents a novel species of the genus , for which the name sp. nov. is proposed. The type strain is AK61 (=JCM 31087=MTCC 12015=KCTC 33872).
