摘要: 以白色链霉菌(Streptomyces albulus)SF-21为出发菌株,对其进行微波诱变、硫酸二乙酯诱变和紫外诱变。在诱变过程中经瓶初筛、复筛获得了高产ε-聚赖氨酸的菌株,ε-聚赖氨酸的产量达0.848g/L,比出发菌株提高了41.3%。经5次传代发酵表明该菌株稳定。
关键词: 诱变, &epsilon, -聚赖氨酸, 白色链霉菌
Abstract: Streptomyces albulus was used as the starting strain and treated with microwave mutation,chemical revulsant and UV irradiation.During mutagenesis process,a high producing ε-polylysine strain was obtained which produces 0.848 g/L increasing 41.3% compared with the staring strain.The mutant showed stable genetic property.
Key words: mutation; &epsilon, -polylysine; Streptomyces albulus;
