Abstract:
By using the tylosin producing Streptomyces fradiae strain 028-3 as a starter,a mutant H188 with a yield of 2 times higher was obtained after three rounds of NTG mutation.After further treatments by means of protoplant regeneration and protoplast mutation,two new mutants, A117 and D85, were obtained and their yields were 6.5 and 5.5 times higher than that of H188,respetively.
