During an attempt to screen secondary metabolites of pharmaceutical utility, we sequenced the complete genome of type strain of a novel marine bacterial genus, named genus Hyphococcus. The type strain, Hyphococcus flavus MCCC 1K03223T, was isolated from bathypelagic seawater of South China Sea at a depth of 2500 m. The complete genome of strain MCCC 1K03223T is composed of a circular chromosome of 3,472,649 bp with a mean G + C content of 54.8%. Functional genomic analysis showed that this genome encodes five biosynthetic gene clusters, which were annotated to synthesize medicinally important secondary metabolites. Secondary metabolites annotated include ectoine which acts cytoprotection, ravidomycin which is an antitumor antibiotic and three other different metabolites of terpene type. The secondary metabolic potentials of H. flavus revealed in this study provide more evidences on mining bioactive substances from marine bathypelagic microorganisms.
