摘　　要：从采自成都市郊森林的土壤中分离纯化到二株粘细菌CS262和CS211。二株粘细菌在琼脂平板上表现出相互抑制子实体发育的拮抗作用。CS211菌株对蜡状芽孢杆菌,藤黄八叠球菌,枯草芽孢杆菌,金黄色葡萄球菌具有很强的抑制作用。采用非极性大孔树脂吸附和TLC方法对抗菌活性物质作了初步研究。CS262 and CS211,two Myxobacteria strains,were isolated from a forest soil sample of Chengdu. We discovered that both of them inhibit each other from developing fruiting body in the agar plate. And we gained crude extracts from the resin added to the fermentation broth of CS211 .Primary study concluded that crude extracts of strain C3211 are natural products with antibiotic activity against Bacillus cereus, Sarcina Lutea, Bacillus subitilis, and Staphylococcus aureus.
