摘要
利用竞争性抑制谷氨酰胺生物合成的方法,从福州郊区土壤中分离到除草活性物质产生菌M-22,其特征与除草剂双丙磷(bialaphos)产生菌吸水链霉菌SF-1293相近,M-22代谢产物FM-22经光谱分析证明与双丙磷同质。
The producing strain S.hygroscopicus M22 of herbicidal active substance was isolated from a soil sample collected in Fuzhou by using the screening model of competitively inhibiting biosynthesis of glutamine. The charateristics of the strain M22 was similar to S.hygroscopicus SF1293, the producer of herbicide bialaphos. The bioactive metabolite of S.hygroscopicus M22 was indicated to be identical with bialaphos by spectrum analysis.
