Venkata and Sasikala, Ch.,, 63, 581-585 (2013), doi = https://doi.org/10.1099/ijs.0.041442-0, publicationName = Microbiology Society, issn = 1466-5026, abstract= Two strains (JC85T and JC108) of Gram-stain-negative, motile bacteria were isolated from endolithic beach sand samples on an oligotrophic medium. Based on the 16S rRNA gene sequence analysis, both strains were identified as belonging to the genus Rhizobium . Strain JC108 had 16S rRNA gene sequence similarity of 100 % with Rhizobium pusense NRCPB10T and formed a cluster with this strain. Strain JC85T had 96.9 % 16S rRNA gene sequence similarity and was 18 % related (based on DNA–DNA hybridization) to Rhizobium borbori DN316T. With other strains of the genus Rhizobium , the 16S rRNA gene sequence similarity was less than 96.3 %. Strain JC85T could tolerate up to 3 % salinity, fix N2, was resistant to ampicillin (10 µg) and was positive for catalase and oxidase. The major fatty acid was C18 : 1ω7c (69 %) with minor amounts of C19 : 0 cyclo ω8c (8.9 %), C16 : 0 (6.9 %), C12 : 0 (5.7 %) and C19 : 1ω7c/C19 : 1ω6c (2.2 %). Polar lipids of strain JC85T include two unidentified aminophospholipids (APL1,2), two unidentified phospholipids (PL1,2), phosphatidylcholine and four unidentified lipids (L1–4). Q-10 is the major quinone of strain JC85T. Based on polyphasic taxonomic analysis, strain JC85T represents a novel species for which, the name Rhizobium subbaraonis JC85T is proposed. The type strain is JC85T ( = DSM 24765T = KCTC 23614T)., language=, type=
