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。
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 potassium effect with the extension of bacteria concentration gradually increased,but did not change the pH.
