| Abstract: | Protoplasts of streptomyces aureofaclens were irradiated by He-Ne laser,the result showed that He - Ne laser had obvious lethal effect on protoplasts. The unit of tetracycline fermentation of regenerate strains after irradiating was tested. Compared with the controlled one,it increased yield by about 9. 32% on average,the highest one increased by about 20. 6%. |
