【摘要】 摇瓶法测定结果表明,用7号培养基,初始pH 7.5,装液量1/10摇瓶体积,转速150 r/min,温度25℃下培养96 h,菌株分泌产生抗番茄青枯病细菌的物质最多,抑菌圈直径最大,为红树植物内生海洋细菌CIII-1菌株产抗植物青枯病菌物质的最佳培养条件。并发现该菌株产生的抗菌物质对西瓜枯萎病菌、香蕉枯萎病菌等植物病原真菌也有较强的拮抗作用。更多还原

【Abstract】 The results of shaking flask test showed that with No 7 medium at initial pH 7.5,filling volume at 1/10(V/V),rpm at 150,and temperature at 25 ℃ culture for 96 h,the CIII-1 strain of endophytic bacterium isolated from leave of mangrove(Bruguiera gymnorrhiza) produced the most antimicrobial substances against tomato green rot(Ralstonia solanacearum).It also found that the antimicrobial substances could inhibit the growth of many pathogenic fungi,such as F.oxysporum f.sp.niveum,F.oxysporum f.sp.cubense etc.更多还原
