| 摘 要： | 对杨树高效解磷细菌蜡状芽孢杆菌(Bacillus cereus)JYZ-SD1和荧光假单胞菌(Pseudomonas fluorescens)JW-JS1在3L发酵罐里发酵条件进行优化。结果显示这两株解磷细菌在72h内都是接种量20%、转速400 r/min、通气量100ln/h条件下菌体生长量最大。为将这两株杨树根际解磷细菌更高效、更大量的扩繁提供参考依据。

| Abstract: | The fermentation conditions of Bacillus cereus JYZ-SD1 and Pseudomonas fluorescens JW-JS1 in a 3L fermentor were optimized.The results indicated that the growth of Bacillus cereus JYZ-SD1 and Pseudomonas fluorescens JW-JS1 during 72h were greatest in the condition of inoculation quantity of 20%,speed of 400 r/min and ventilation of 100 ln/h.This study is for the development and application of effective phosphate dissolving bacteria on the production of poplars. |
