摘要： The genus Serratia is a typical red bacterium involved in prodigiosin synthesis. Here, we report the genome sequence of Serratia rubidaea XU1, which was isolated from radiation-contaminated soil in Xinjiang, China. The genome of XU1 is composed of 4,972,898 base pairs with a GC content of 59.25%. The genome sequence contains 4707 genes and encodes 4573 proteins, 79 tRNAs, and 17 rRNAs. The prodigiosin biosynthesis gene cluster was identified and analyzed, showing a sequence similarity of 85.55-96.02% with Serratia rubidaea. After optimizing the biosynthesis process, XU1 was able to achieve a maximum titer of 574 units/cell of prodigiosin at a pH of 7.5 and a temperature of 25 degrees C for 36 h. Glycerol at 20 g/L and beef extract at 5 g/L were used as the carbon and nitrogen sources, respectively. Prodigiosin extracted from XU1 demonstrated inhibition of Escherichia coli, Staphylococcus aureus, Enterococcus faecalis and Pseudomonas aeruginosa. The availability of the sequenced genome of XU1 will be greatly beneficial and contribute to complementary studies on the biosynthetic mechanisms of prodigiosin.
