【摘要】 目的:研究γ-癸内酯高产菌的诱变选育;方法:Yarrowia lipolytica As2.1405经过连续紫外诱变、NTG诱变、DES诱变和钴60诱变,最终筛选得到一株高产内酯菌种167#,摇瓶平均产量为1.4g/L;结论:通过复合诱变,大大提高了菌株生产γ-癸内酯的能力。更多还原

【Abstract】 Objective: To study the Breeding of high - gamma -decalactone -yielding strain mutated by combinated mutagenesis. Methods: The original strain was mutanted by Ultraviolet (UVB), NTG, DES and Co60 successively, and then a new industrial strain 167# which could generate 1.4 g/L of gamma-decalactone was optimized. Conclusion: Through combinated mutagenesis, the gamma-decalactone productivity by the mutant strain was improved very much.更多还原
