Microvirga massiliensis sp. nov. strain JC119(T) is a bacteria isolated in Marseille from a stool sample collected in Senegal. The 16S rRNA (JF824802) of M.massiliensis JC119(T) revealed 95% sequence identity with Microvirga lotononidis WSM3557(T) (HM362432). This bacterium is aerobic, gram negative, catalase positive, and oxidase negative. The draft genome of M.massiliensis JC119(T) comprises a 9,207,211-bp-long genome that is the largest bacterial genome of an isolate in humans. The genome exhibits a G+C content of 63.28% and contains 8685 protein-coding genes and 77 RNA genes, including 21 rRNA genes. Here, we describe the features of M.massiliensis JC119(T), together with the genome sequence information and its annotation.
