A Gram-reaction-negative halotolerant bacterial strain, designated Ka21T, was isolated from agricultural soil and characterised using a polyphasic approach to determine its taxonomic position. On the basis of 16S rRNA gene sequence analysis, highest similarity was found with Sphingobacterium alkalisoli Y3L14T (96.72%). Cells were observed to be aerobic, non-motile rods. The isolate was found to be able to grow between 0 and 10% of NaCl concentration. The assembled genome of strain Ka21T has a total length of 5.2 Mb with a G + C content of 41.0 mol%. According to the genome analysis, Ka21T encodes several glycoside hydrolases that may play a role in the degradation of accumulated plant biomass in the soil. Based on phenotypic characteristics and phylogenetic analysis, it is concluded that strain Ka21T represents a novel species in the Sphingobacterium genus for which the name Sphingobacterium pedocola sp. nov. is proposed. The type strain of the species is strain Ka21T (= LMG 31575T = NCAIM B.02636T).

Sphingobacterium pedocola sp. 十一月 从农业土壤中分离出的一种新型耐盐细菌

从农业土壤中分离出一种革兰氏反应阴性耐卤细菌菌株,命名为 Ka21 T,并使用多相方法确定其分类位置。在16S rRNA基因序列分析的基础上,发现与碱性鞘氨醇Y3L14 T相似性最高(96.72%)。观察到细胞是需氧的、非运动的杆。发现分离物能够在 0% 到 10% 的 NaCl 浓度之间生长。Ka21 T菌株的组装基因组总长度为5.2 Mb,G + C含量为41.0 mol%。根据基因组分析,Ka21 T编码几种可能在土壤中积累的植物生物量降解中起作用的糖苷水解酶。根据表型特征和系统发育分析,得出的结论是,菌株 Ka21 T代表了鞘氨醇杆菌属中的一个新物种,其名称为Sphingobacterium pedocola sp。十一月 被提议。该物种的典型菌株是菌株 Ka21 T (= LMG 31575 T  = NCAIM B.02636 T )。
