The experiment provides the physiological characteristics of ZL-1,the mutant of Streptomyces lincolnensis from SL98-2-8.When inoculated,the strain ZL-1 can be mature on the Slant medium 4 days later.48 hours later,the Seed medium can be used,the shaking cycle is 5 days,and the final production reaches 2867μg/mL.Compared with the original strain SL98-2-8,3024μg/mL,the final production of ZL-1 reduces by 5.2%,but its slant culture cycle,seed culture cycle and shaking cycle reduce by 2 days,6 hours and 2 days respectively.General fermentation period reduces by more than 4 days.During 10 generationits,the characters of ZL-1 is proved stable.
