- 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 de-termined their ability to solution of potassium.The results showed:after dilute the samples of different regions andbiologicalfertilizer, there were only a few samples could separate the strains of potassium.The results of Gram staining and catalaseexperiment, nitrate reduction test, starch hydrolysis experiments V.P.tests indicated negative.Preliminary experiments iden-tified as Bacillus.Pathogen potassium effect with the extension of bacteria concentration gradually increased, but did notchange the pH.
