Abstract
Experiments with a number of bacteria isolated from activated sludge have shown that flocculation is independent of the presence of poly-beta-hydroxybutyrate (PHB) in the cells. Several strains gave flocculent growth without any PHB detectable. Other strains, producing PHB in varying amounts, utilized this compound as an endogenous substrate, and after its disappearance the floc structure remained unchanged. The PHB content of various samples of activated sludge was found to be negligible.
摘要
对从活性污泥中分离出的多种细菌进行的实验表明，絮凝作用与细胞中聚-β-羟基丁酸酯（PHB）的存在无关。有几种菌株在未检测到任何PHB的情况下呈现絮凝生长。其他菌株产生不同量的PHB，它们将这种化合物用作内源性底物，在其消失后，絮凝结构保持不变。发现活性污泥的各种样品中的PHB含量可忽略不计。
