| 摘 要： | 用无氮培养基从土壤中选出2株菌种,然后对菌种进行分离、鉴定以及对解钾能力进行测定。结果表明：对不同地区及生物肥料样品进行稀释倒皿后,只有少数样品中分离到解钾菌株。该菌通过革兰氏染色实验、过氧化氢酶实验、硝酸盐还原实验、淀粉水解实验和V.P.实验等初步鉴定为芽孢杆菌。该菌解钾效果随时间的延长菌浓度逐渐增加,但pH变化不明显。

| Abstract: | Two bacteria were elected from soil by no-nitrogen medium,and then the bacteria were isolated,identified and determined their ability to solution of potassium.The results showed:after dilute the samples of different regions and biological fertilizer,there were only a few samples could separate the strains of potassium.The results of Gram staining and catalase experiment,nitrate reduction test,starch hydrolysis experiments V.P.tests indicated negative.Preliminary experiments identified as Bacillus.Pathogen p... |
