摘要: 考察了复合型微生物絮凝剂产生菌在40~160 MPa高压处理前后的形态、 生理生化性质及代谢产物的絮凝活性变化. 结果表明, 高压对复合菌的形态有明显的影响, 对菌的生理生化性质影响较小. 絮凝活性实验表明, 高压作用下, 2号组成菌代谢产物的絮凝活性有明显的压力阈值, 在70 MPa时, 其絮凝率为60.9%, 而复合菌代谢产物的絮凝活性无明显变化, 几种压力下絮凝率皆在95%以上.

Abstract: Before and after the treatment of high pressures ranged from 40~160 MPa, the p hysiological and biochemical characters and the flocculating activity of the metabolites of bioflocculantproducing compound bacterium were investigated. The results suggest that high pressures partly impacted the physiological and biochemical characters but had significant effects on the morphology. Furthermore the flocculating activity of bacterium No.2 had an obvious threshold of pressure, its ratio of flocculation was 60.9% at 70 MPa, but that of bioflocculantproducing compound bacterium changed little. The ratios of flocculation were all above 95% under various pressures.

Key words: high pressure, compound bacterium, flocculating activity
