简述了微生物杀菌剂的使用现状及利用遗传改良改造农用抗生素产生菌的研究现状,重点介绍了产生新抗生素方法的研究进展,包括利用组合生物技术产生新的抗生素、通过激活抗生素的沉默基因获得新的抗生素及利用基因重组技术改良抗生素的生产菌等。
The current status of the use of microbial biocides and the status quo of genetic improvement of agricultural antibiotic-producing bacteria are briefly introduced. The research progress of new antibiotic production methods is highlighted, including the use of combinatorial biotechnology to generate new antibiotics and the activation of antibiotic silencing genes New antibiotics and the use of gene recombination technology to improve the production of antibiotics and other bacteria.
