Initiating biodegradation of polyvinylpyrrolidone in an aqueous aerobic environment

Original language description

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
