摘　　要：从紫色土壤中分离筛选出具有解钾拮抗双重活性的硅酸盐细菌CS1和CS2 9菌株 .接菌处理 ,其水溶性钾分别增加 75 %和 6 5 % ,转化率达 0 .82 %和 0 .72 % .两株菌对革兰氏阳性的蜡样芽孢杆菌 ,金黄色葡萄球菌 ,藤黄八叠球菌等和革兰氏阴性的大肠杆菌均有较强的抑菌活性 .筛选菌株中 91.2 %具有解钾活性 ,但拮抗活性菌株只占总数的11.6 % ,表明二性状之间无相关关系 .表 4参Two strains of silicate bacteria, CS 1 and CS 29 with dual activity of potassium- releasing and antagonism, were isolated from purple soil. The dissolved potassium treated with the two strains was increased by 75% and 65%, and transformation rate reached 0.82% and 0.72%, respectively. The two strains showed a significant activity in inhibiting the growth of gram-positive bacteria, such as Bacillus cereus, Staphylococcus aureus and Sarcina luteus, as well as gram-negative bacteria, such as Escherichia coli. However, there is no relationship between potassium-releasing and antagonistical activities since 91.2% of all the test strains had activity of releasing potassium, whereas only 11.6% of all expressed antagonistical activity. Strain CS1 was identified as Bacillus mucilaginosus. Tab 4, Ref 7
