不同生存环境和磷酸盐对4株溶磷菌溶磷能力的影响
DOI: 10.3724/SP.J.1145.2009.00856, PP. 856-860
Keywords: 溶磷菌,生存环境,nacl浓度,碳源,氮源,溶解氧,磷酸盐,溶磷能力
Abstract:
利用液体培养法研究了不同nacl浓度、碳源、氮源、溶解氧及磷酸盐对分离自小麦（triticumaestivum）、苜蓿(medicagosativa)根际的4株优良溶磷细菌（lx81、jm92、dm84、lx191）溶磷能力的影响.结果表明：（1）4株溶磷菌均为高耐盐菌株，其中jm92和dm84维持较高溶磷量的nacl浓度最高阈值分别为4％和8%，lx81、lx191在nacl浓度超过5%时溶磷活性受到抑制.（2）lx81的最佳碳源是葡萄糖，其次为蔗糖；另外3株菌在葡萄糖和蔗糖为碳源时，均有较高的溶磷能力；4株菌都几乎不能利用淀粉.（3）lx81和jm92在以(nh4)2so4和nh4no3为氮源时溶磷活性均较高，(nh4)2so4是lx191的最佳氮源，而nh+-n存在会导致dm84溶磷活性降低.（4）供试4株菌均不是专性厌氧菌，但不同菌株对氧的需求量不同.（5）4株溶磷菌对ca3-p和ca8-p有较大的溶解效率，但它们几乎都不能溶解ca10-p.图3表4参14
