Complete Genome Sequence of Strain YCSC6, a Marine Bacterium Isolated from Saturated Saltpan with Activity Against Uronema marinum.

ABSTRACT

Salinivibrio proteolyticus strain YCSC6 was isolated from a saturated saltpan and demonstrated to have strong insecticidal activity against turbot's pathogenic ciliate-Uronema marinum. In this study, we sequenced its complete genome. Results showed that it consists of two circular chromosomes 2.49 Mbps and 0.74 Mbps, respectively. It encodes 3429 protein-coding sequences. Biosynthetic gene clusters predicted to synthesize bacteriocins and antimicrobial peptides were discovered, which might be the key factors to lyse and kill U. marinum. The complete genome sequence of strain YCSC6 provides insights into the fundamental genetic potential for elucidating its insecticidal mechanism against U. marinum.
