A synthetic medium has been developed in which Streptococcus faecalis var. zymogenes X-14 elaborates a lysin. The medium consists of 18 amino acids, lactose, six vitamins, adenine, guanine, uracil, and six salts. Glucose, and K(2)HPO(4) in excess of 0.5% (wt/vol), were inhibitory to lysin production; increasing concentrations of l-arginine-hydrochloride gave increasing yields of lytic activity.
已开发出一种合成培养基,其中粪肠球菌变种产酶 X-14 可产生溶菌酶。该培养基包含 18 种氨基酸、乳糖、6 种维生素、腺嘌呤、鸟嘌呤、尿嘧啶和 6 种盐。葡萄糖和超过 0.5%(wt/vol)的 K(2)HPO(4)对溶菌酶的产生有抑制作用;增加 l-精氨酸盐酸盐的浓度可提高溶菌活性的产量。
