Marinimicrobium alkaliphilum sp. nov., an alkaliphilic bacterium isolated from soil and emended description of the genus Marinimicrobium Song, Lei and Liu, Hongcan and Cai, Shichun and Zhou, Yuguang,, 69, 481-485 (2019), doi = https://doi.org/10.1099/ijsem.0.003183, publicationName = Microbiology Society, issn = 1466-5026, abstract= Two Gram-stain-negative, rod-shaped bacterial strains, designated SW121T and W12, were isolated from a soil sample collected from Shanxi Province, China. The two strains were strictly aerobic, catalase-positive and oxidase-positive. Both strains grew at 6–42 °C (optimum, 30 °C), at pH 5.5–11.0 (optimum, pH 9.0) and in the presence of 0–15.0 % (w/v) NaCl (optimum, 2.0–3.0 %). The predominant cellular fatty acids of strain SW121T were C16 : 0, C18 : 1ω7c and summed feature 3 (comprising C16 : 1ω7c and/or C16 : 1ω6c). Strain SW121T contained ubiquinone-8 as the sole respiratory quinone. Diphosphatidylglycerol, phosphatidylethanolamine and phosphatidylglycerol were major polar lipids. The genomic DNA G+C content of strain SW121T was 58.5 mol%. Comparative analysis of 16S rRNA gene sequences revealed that strains SW121T and W12 showed the highest similarities to Marinimicrobium koreense DSM 16974T(95.7 and 95.5 %, respectively). On the basis of phylogenetic inference and phenotypic characteristics, it is proposed that the two strains represent a novel species of the genus Marinimicrobium , for which the name Marinimicrobium alkaliphilum sp. nov. is proposed. The type strain is SW121T (=CGMCC 1.16166T=KCTC 62651T)., language=, type=
