农用抗生素产生菌菌种选育的研究进展

The Research and Development of Agricultural Antibiotic Produced Strains Selective Breeding

农用抗生素产生菌的原始菌株 ,往往产量很低或质量较差 ,不能满足工业生产的需要 ,必须对它的某些性状进行改良。改良菌种的主要手段是通过育种 ,筛选出高产菌株。传统的诱变育种是最广泛的选育方法 ,以基因工程为核心的现代生物技术也应用于农用抗生素产生菌的菌种选育中 ,并逐渐成为农用抗生素菌种选育的主导技术。

The original strains producing agricultural antibiotic is always low in output or bad in quality,it can not meet the requirement of industrial production. So it is necessary to improve some of its characters. The main way of improvement is culturing and selecting high output strains. The traditional way for selecting strains is wide way, the modern microbiologic technology taking the gene engineering as center is also applied for strains breeding,and it becomes the main way gradually.
