재조합 대장균을 이용한 재조합 Glucagon-like Peptide-1 생산 조건 최적화

초록

Obesity is well known as a metabolic abnormality and potentially life-threatening condition associated with several chronic diseases. Various peptide drugs have been developed to treat obesity. In this study, optimization of expression conditions were performed to produce glucagon-like peptide- 1 (GLP-1), which is used as an obesity treatment in recombinant E. coli. After the construction of expression vector system and optimization of expression conditions, the productivity of GLP-1 was increased to 11.18 mg/L·h in flask cultivation. Through fermentation conditions were optimized for bioreactor, the GLP-1 productivity was increased to 16.80 mg/L·h in bioreactor, which was 50.27% improvement as compared to the flask cultivation. When 1.00 mM lactose was used as an inducer instead of IPTG, 17.39% higher expression was shown than that with 0.01 mM IPTG.
