Corynebacterium deserti sp. nov., isolated from desert sand

Abstract

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 GIMN1.010Tbelonged 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 GIMN1.010Tand C. glutamicum ATCC 13032Twas only 22.4±1.72 %, showing that strain GIMN1.010Trepresented a genomic species distinct from C. glutamicum. On the basis of phenotypic and phylogenetic data, strain GIMN1.010Tis 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). © 2012 IUMS.
