Abstract

Biodegradation of nonylphenol polyethoxylates (NPEO) has been studied in laboratory column bioreactors with a polyethylene carrier on which destructor bacteria of Pseudomonas surface-active compounds were immobilized. To monitor the efficiency of microbial treatment of model wastewater, a biosensor based on the oxygen Clark electrode and destructor bacteria of NPEO from bioreactors was designed. The designed biosensor allowed us to detect the content of polyethylene glycol monoalkyl phenyl ether on the basis of polymer distillate (OP-10), which is a commercial NPEO preparation, in samples in the range of 1-200 mg/l. Operation of the biosensor was stable within 7 days with the standard deviation of 1.35 mg/l for 20 consecutive measurements of OP-10 concentration, which was 20 mg/l (7%).
