abstract: A rod-shaped, motile, Gram-stain-positive bacterial strain RKN2T, was isolated from gut of silver carp (Hypophthalmichthys molitrix) residing in Gobindsagar reservoir, Himachal Pradesh, India. Having the greatest sequence similarity to Sporosarcina koreensis F73T (98.51%), Sporosarcina luteola Y1T (98.4%) and Sporosarcina aquimarina SW28T (98.36%), the 16S rRNA gene phylogeny confirmed the belonging of strain RKN2T to genus Sporosarcina. Digital DNA-DNA hybridization values were 21.7%, 20.6%, and 19.2%, and average nucleotide identity values were 76.42%, 80.16%, 76.51%, of strain RKN2T with Sporosarcina koreensis F73T, Sporosarcina luteola Y1T, and Sporosarcina aquimarina SW28T, respectively. The genomic analysis of strain RKN2T showed various biological properties including nitrate reduction, genes responsible for carbohydrate-active enzymes production, antimicrobial compounds, as well as potential metabolism of aromatic compounds and heavy metals. G+C composition of RKN2T genome was 52.7%. This strain can grow in temperatures between 10°C and 40°C (optimum, 28°C-30°C), NaCl concentrations up to 6.0% (w/v), and 6.0-8.0 (optimum, 6.5-7.5) pH range. MK-7 was the dominant respiratory quinone, A-4 type cell wall peptidoglycan was present with anteiso-C15:0, iso-C15: 0, and anteiso-C17:0 being the major fatty acids and Lys-Glu being main amino acids. Diphosphatidylglycerol, phosphatidylglycerol, and phosphatidylethanolamine were the strain RKN2T's three main polar lipids. The strain is a novel species under genus Sporosarcina based on polyphasic approach and the name Sporosarcina hypophthalmichthys sp. nov. is given for strain RKN2T. RKN2T is a type strain (= MCC 4365T = JCM34522T = CCM9112T).
