Bacterial strains with a high biodegradation potential were isolated from activated sludge. Their ability to decompose the hard bis-quaternary ammonium salt FB was determined by the method of chemical oxygen demand (COD) in a mineral medium, where the compound FB was the only source of carbon. The COD values were very low after 21 d and in the course of this period they reached zero level twice. The contribution of adsorption to decrease the COD value was small. The maximum COD decrease was accompanied by an increase of cell respiration. It is suggested that FB is effectively decomposed in spite of the fact that according to its structure it is a typical hard detergent.
从活性污泥中分离出具有高生物降解潜力的细菌菌株。在以化合物FB为唯一碳源的矿物培养基中，通过化学需氧量（COD）法测定了它们分解硬双季铵盐FB的能力。21天后COD值非常低，在此期间它们两次达到零水平。吸附对降低COD值的贡献很小。最大的COD降低伴随着细胞呼吸的增加。尽管根据其结构它是一种典型的硬洗涤剂，但仍表明FB能被有效分解。
