Abstract
For the isolation of a εcaprolactamdegrading microbe from wastewaters of a factory producing caprolactam we applied a chemostatenrichment technique with a selective medium containing caprolactam as sole source of carbon and nitrogen This allowed for the isolation of a novel caprolactamdegrading microbe identified as Acinetobacter calcoaceticus The strain had a critical tolerance of 19 g caprolactam l−1 in minimal medium which is higher than any previously reported caprolactamdegrading microbe A calcoaceticus also decreased the caprolactam content in medium by 65 within 72 h despite the high caprolactam content 10 g l−1 This study highlights the potential use of A calcoaceticus strain for the bioremediation of recalcitrant synthetic polymers such as caprolactam
