International audience. Strain G3(T) (CSUR P207 = DSM 26203) was isolated from the fecal sample of a wild gorilla (Gorilla gorilla subsp gorilla) from Cameroon. It is a Gram-positive, facultative anaerobic short rod. This strain exhibits a 16S rRNA sequence similarity of 98.2 % with Microbacterium thalassium, the closest validly published Microbacterium species and member of the family Microbacteriaceae. Moreover, it shows a low MALDI-TOF-MS score (1.1 to 1.3) that does not allow any identification. Thus, it is likely that this strain represents a new species. Here we describe the phenotypic features of this organism, the complete genome sequence and annotation. The 3,692,770 bp long genome (one chromosome but no plasmid) contains 3,505 protein-coding and 61 RNA genes, including 4 rRNA genes. In addition, digital DNA-DNA hybridization values for the genome of the strain G3(T) against the closest Microbacterium genomes range between 19.7 to 20.5, once again confirming its new status as a new species. On the basis of these polyphasic data, consisting of phenotypic and genomic analyses, we propose the creation of Microbacterium gorillae sp. nov. that contains the strain G3(T).
