| 摘 要： | 青枯病是危害大、分布广、损失重的植物病害之一。生防菌株PBW1对植物青枯病的防效可高达70％以上。本文研究了溶氧浓度对PBW1生长的影响， PBW1生长的临界溶氧浓度为25.5%；摇瓶与发酵罐培养的结果均表明，溶氧浓度越高，越有利于菌体的生长。

| Abstract: | Plant bacterial wilt disease is one of the diseases most widely distributed and seriously harmful to plants. Strain PBW1 can biologically control plant bacterial wilt disease with the efficiency of higher than 70%. In this paper, the effect of dissolved oxygen concentration on strain PBW1 growth was studied. The critical dissolved oxygen concentration of strain PBW1 is 25.5%. The cultural results of flask and fermentation showed that the higher the dissolved oxygen concentration, the quicker strain PBW1 grew. |
