Colistin 생산균주의 균주개량 및 productivity 증대를 위한 발효최적화
초록
Colistin produced from Penibacillius polymyxa was widely used as an antibiotic active against gram-negative bacteria and as feed additive. This research studied on increment of colistin productivity by mutation of P. polymyxa. As a result, several mutants were obtained from the strain by UV radiation and NTG treatment. They produced approximately 8.5
