摘要：

N-methyl-2-pyrrolidone (NMP) is a widely used solvent for many organic compounds and a component found in a vast array of chemical preparations. For this research paper, NMP degrading bacteria were isolated from two samples of activated sludge. They pertained to both Gram-negative and Gram-positive members, and belong to the Pseudomonas, Paracoccus, Acinetobacter and Rhodococcus genera. All the strains utilized 300 mg/L of NMP as the only source of carbon, energy and nitrogen over several days, and they were shown to additionally be able to degrade N-acetylphenylalanine (NAP). The growth of all the isolated strains was recorded at different NMP concentrations, to a maximum of 20 g/L.
