工业微生物育种技术研究进展

DEVELOPMENTS OF THE BREEDING OF INDUSTRIAL MICROBE

工业微生物育种是运用遗传学原理和技术对某种具有特定生产目的的菌株进行改造,去除不良性质,增加有益新性状,以提高产品的产量和质量的一种育种方法.工业微生物的育种技术已从常规的突变和筛选技术发展到基因诱变、基因重组和基因工程等,育种技术的不断成熟,大大提高了微生物的育种效果.

Industrial microbe breeding is to apply genetic principles and techniques to reform some special productive strains and get rid of their harmful natures or add some beneficial characters.With its rapid development,breeding techniques have gene induce mutation,gene recombination,gene engineering and other modern methods.Breeding techniques are developing,and the breeding efficiency has been improved.
