Název v původním jazyce

Initiating biodegradation of polyvinylpyrrolidone in an aqueous aerobic environment

Popis výsledku v původním jazyce

The paper investigates the potential to initiate aerobic biodegradation of polyvinylpyrrolidone (PVP) in the presence of activated sludge from a municipal wastewater treatment plant. The following agents were selected as the initiators of the biodegradation process - co-substrates: acrylamide, N-acethylphenylalanine and 1-methyl-2-pyrrolidone, a substance with a similar structure to PVP monomer. The biodegradability of PVP in the presence of co-substrates was evaluated on the basis of biological oxygendemand (BOD). The total substrate concentration in the suspension equaled 400 mg.L-1, with the ratio between PVP and the co-substrate being 1:1, while the concentration of the dry activated sludge was 500 mg.L-1. Even though there was no occurrence of asignificant increase in the biodegradation of PVP alone in the presence of a co-substrate, acrylamide appeared to be the most effective type of co-substrate. Nevertheless, a recorded decrease in the slope of biodegradation curves over tim
