测定了 2 6株链霉菌对番茄早疫病菌、番茄灰霉病菌、甘蓝黑腐病菌、白菜软腐病菌和大肠杆菌这 5种病原菌的抑菌作用。结果发现 :在供试的 2 6株链霉菌中 ,菌株Men -myco - 93- 6 3、6 3、Mycostop、GS - 93- 10、GS - 93 - 3和GS - 93- 2 3对番茄早疫病菌 ,菌株 15、6 3、GS - 93- 10、93和Mycostop对番茄灰霉病菌 ,菌株 32、GS - 93- 2、GS - 93- 3、GS - 93 - 2 3和 93对甘蓝黑腐病菌 ,菌株GS - 93- 3、GS - 93- 2 31、GS - 93- 10和Men -myco - 93- 38对大肠杆菌抑菌作用较强 ,它们的抑菌活性明显高于对照化学药剂 ,白菜软腐病菌无抑菌活性强的菌株 ,只有菌株GS - 93 -10和GS - 93- 2 31抑菌活性中等
The antibacterial activity of 26 strains of Streptomyces against five pathogens such as Alternaria solani, Botrytis cinerea, Cabbage black rot, Cabbage soft rot and Escherichia coli were measured. The results showed that among the 26 Streptomyces strains tested, the strains Men-myco-93- 6 3,6 3, Mycostop, GS-93-10, GS-93-3 and GS-93-2 3 Inoculation of Botrytis cinerea, Strain 32, GS - 93 - 2, GS - 93 - 3, GS - 93 - 23 and 93 against cabbage black The bacteriostasis strains GS - 93 - 3, GS - 93 - 2 31, GS - 93 - 10 and Men - myco - 93 - 38 had stronger antibacterial activity against Escherichia coli and their antibacterial activities were significantly higher than that of the control chemicals , Cabbage soft rot fungi without strong antibacterial activity of strains, only strain GS - 93 -10 and GS - 93 - 2 31 antibacterial activity of medium
