Abstract：
A Gram-stain-positive, aerobic, non-mobile and spherical strain, designated ZS9-10T, belonging to the genus Deinococcus was isolated from soil sampled at the Chinese Zhong Shan Station, Antarctica. Growth was observed in the presence of 0-4 % (w/v) NaCl, at pH 7.0-8.0 and at 4-25 °C. Phylogenetic analysis based on 16S rRNA gene sequences showed that strain ZS9-10T formed a lineage in the genus Deinococcus. It exhibited highest sequence similarity (97.4 %) to Deinococcus marmoris DSM 12784T. The major phospholipids of ZS9-10T were unidentified phosphoglycolipid, unidentified glycolipids and unidentified lipids. The major fatty acids were summed feature 3 (C16 : 1 ω7c and/or C16 : 1 ω6c), C16 : 0 and C16 : 1 ω7c. MK-8 was the predominant respiratory quinone. The digital DNA-DNA hybridization and average nucleotide identity values between strain ZS9-10T and its close relative D. marmoris DSM 12784T were 27.4 and 83.9 %, respectively. Based on phenotypic, phylogenetic and genotypic data, a novel species, named Deinococcus arenicola sp. nov., is proposed. The type strain iis ZS9-10T (=CCTCC AB 2019392T=KCTC43192T).
摘要：
革兰氏染色阳性，有氧,非移动和球形应变，指定ZS9-10T,从中国中山站采样的土壤中分离出属于异常球菌属，南极洲。在0-4％（w/v）NaCl存在下观察到生长，pH7.0-8.0和4-25°C。基于16SrRNA基因序列的系统发育分析表明，菌株ZS9-10T在异常球菌属中形成了谱系。它与马氏异常球菌DSM12784T表现出最高的序列相似性(97.4%)。ZS9-10T的主要磷脂是未鉴定的磷酸糖脂，未知的糖脂和未知的脂质。主要脂肪酸的总和特征为3（C16：1ω7c和/或C16：1ω6c），C16:0和C16:1ω7c。MK-8是主要的呼吸醌。菌株ZS9-10T与其近亲D.marmorisDSM12784T之间的数字DNA-DNA杂交和平均核苷酸同一性值分别为27.4％和83.9％，分别。基于表型，系统发育和基因型数据，一个新的物种,命名为红土球菌。11月。,是提议的。菌株类型为ZS9-10T(=CCTCCAB2019392T=KCTC43192T)。
