A novel coryneform bacterium, designated strain GIMN1.010T, was isolated from a sand sample collected in the desert in the west of China. Cells were Gram-stain-positive, non-spore-forming, catalase-positive, irregular rods. Comparative 16S rRNA gene sequence analysis demonstrated that strain GIMN1.010T belonged to the genus Corynebacterium and was related closely to Corynebacterium glutamicum ATCC 13032T (98.4 % similarity). However, the level of DNA-DNA relatedness between strain GIMN1.010T and C. glutamicum ATCC 13032T was only 22.4±1.72 %, showing that strain GIMN1.010T represented a genomic species distinct from C. glutamicum. On the basis of phenotypic and phylogenetic data, strain GIMN1.010T is considered to represent a novel species of the genus Corynebacterium, for which the name Corynebacterium deserti sp. nov. is proposed. The type strain is GIMN1.010T (=CCTCC AB 2010341T=NRRL B-59552).
一株新的棒状杆菌，命名为菌株 GIMN1.010T，是从中国西部沙漠的沙样中分离得到的。细胞革兰氏阳性，不产芽孢，过氧化氢酶阳性，呈不规则杆状。比较 16S rRNA 基因序列分析表明，菌株 GIMN1.010T 属于棒状杆菌属，与谷氨酸棒状杆菌 ATCC 13032T 密切相关（相似度为 98.4%）。然而，菌株 GIMN1.010T 与谷氨酸棒状杆菌 ATCC 13032T 之间的 DNA-DNA 同源性水平仅为 22.4±1.72%，表明菌株 GIMN1.010T 代表了一个与谷氨酸棒状杆菌不同的基因组种。基于表型和系统发育数据，菌株 GIMN1.010T 被认为代表了棒状杆菌属的一个新种，因此提议将其命名为荒漠棒状杆菌（Corynebacterium deserti sp. nov.）。其模式菌株为 GIMN1.010T（=CCTCC AB 2010341T=NRRL B-59552）。
