| Abstract: | In order to screen a high-yielding tetramycin strain from Streptomyces 11371,protoplasts preparation and regeneration of the strain was groped.The results showed that the optimum conditions for the preparation and regeneration of the protoplasts were as follows: concentration of glycine was at 0.7%,culture temperature 28 ℃,culture for 42 h,lysozyme 3 mg/mL,enzymolysis temperature 37 ℃,and enzymolysis for 90 min.The optimum medium for the regeneration was R2YE. |
