5 : (Bacillus amyloliquefacien) Macrolactin A 1077 OPTIMIZATION OF CARBON RESOURCE FOR MACROLACTIN A PRODUCTION FROM MARINE BACILLUS AMYLOLIQUEFACIEN HOU Dong-Yuan, WU Zu-Fang, ZHANG Xin (Ningbo University, Key Laboratory of Applied Marine Biotechnology of Ministry of Education, Ningbo 315211, China) Abstract To optimize the production of Macrolactin A from a marine Bacillus amyloliquefaciens ESB-2, we extract crude material with macroporous adsorptive resin and then purified in high-speed counter-current chromatography (HSCCC). The purity of separated component was determined and the influence of different carbon sources on Macrolactin A yield was detected, in high performance liquid chromatography (HPLC). The fermentation curve of marine Bacillus amyloliquefaciens was obtained under optimization condition. The results show that Macrolactin A could be purified quickly in HSCCC, and the purity of the product reached >95%. The carbon sources of glucose, sucrose, and maltose were conducive for the accumulation of Macrolactin A, and maltose was the best carbon source at concentration of 1%, under which the concentration of Macrolactin A could reach 18.5 mg/l and the production was more than doubled. Key words high-speed counter-current chromatography (HSCCC); Bacillus amyloliquefaciens; Macrolactin A; carbon resource optimization
