Â© 2015 Aghnatios et al. Gemmata massiliana is a new Planctomycetes bacterium isolated from a hospital water network in France, using a new culture medium. It is an aerobic microorganism with optimal growth at pH 8, at 30 Â°C and salinity ≤ 1.25 % NaCl. G. massiliana is resistant to β-lactam antibiotics, due to lack of peptidoglycan in its cell wall.G. massiliana shares a 97 % 16S rRNA gene sequence similarity with the nearest species, Gemmata obscuriglobus; and 99 % similarity with unnamed soil isolates. Its 9,249,437-bp genome consists in one chromosome and no detectable plasmid and has a 64.07 % G + C content, 32.94 % of genes encoding for hypothetical proteins. The genome contains an incomplete 19.6-kb phage sequence, 26 CRISPRs, 3 CAS and 15 clusters of secondary metabolites. G. massiliana genome increases knowledge of a poorly known world of bacteria.
