STRAIN PRODUCING REMARKABLE AMOUNT OF ε-POLY-L-LYSINE AND PROCESS FOR PRODUCING ε-POLY-L-LYSINE BY USING THE SAME

A strain which has an enhanced ability to produce ε-poly-L-lysine as compared with the conventional ε-poly-L-lysine-producing strains or improved varieties thereof, and is capable of elevating ε-poly-L- lysine productivity; and a process for producing a remarkable amount of ε-poly-L-lysine by using this strain which comprises mutagenizing a microorganism capable of producing ε-poly-L-lysine and belonging to the species Streptomyces albulusto thereby give a strain being tolerant to S-(2-aminoethyl)-L-cysteine at a high concentration of 10 mg/ml or above and capable of producing ε-poly-L-lysine, aerobically incubating this strain in a medium, and collecting the ε-poly-L- lysine from the culture. © KIPO & WIPO 2007 ...

Strain producing remarkable amount of epsilon-poly-L-Lysine and process for producing same

A strain which has an enhanced ability to produce 'epsilon'-poly-L-Lysine as compared with the conventional 'epsilon'-poly-L-Lysine-producing strains or improved variesties thereof, and is capable ofelevating 'epsilon'-poly-L-Lysine productivity; and a process for producing a remarkable amount of 'episilon'-poly-L-Lysine by using this strain which comprises mutagenizing a microorganism capable of producing 'epsilon'-poly-L-Lysine and belonging to the species Streptomyces albulus to thereby give a strain being tolerant to S-(2-aminoethyl)-L-cysteine at a high concentration of 10 mg/ml or above and caapble of producing 'epsilon'-poly-L-Lysine, aerobically incubating this strain in a medium, and collecting the 'epsilon'-poly-L-Lysine from the culture.

大量产生ε-聚-L-赖氨酸的菌株和生产方法

... 本发明提供了具有较常规ε-聚-L-赖氨酸产生菌更高的ε-聚-L-赖氨酸生成能力并能提高ε-聚-L-赖氨酸产率的菌株或其改良菌株，以及使用该菌株大量生产ε-聚-L-赖氨酸的方法。根据该生产ε-聚-L-赖氨酸的方法，对属于小白链霉菌、具有ε-聚-L-赖氨酸生成能力的微生物进行诱变处理，以获得可大量产生ε-聚-L-赖氨酸并对浓度为10mg/ml或更高的S-(2-氨基乙基)-L-半胱氨酸具有抗性的菌株，好气条件下在培养基中培养该菌株，收集培养物中形成的ε-聚-L-半胱氨酸。 ...
