摘要：
Cultivation conditions affecting poly(vinyl alcohol) (PVA) degradation by a mixed bacterial culture of Bacillus sp. and Curtobacterium sp. were investigated. Bacterial strains used in this study were isolated from the watercourse and the sewage sludge of vinylonfibre mill by enrichments on PVA as the sole carbon source. The results showed that PVA was greatly degraded under the following conditions: 0.5% PVA as a substrate at the initial medium pH of 8 with 0.15% glucose and urea at C/U ratio 1.5:1 and 1% bacterial inoculum, at a temperature of 35 °C and a shaking speed of 110 rpm. The analysis of FTIR and 1H NMR spectra before and after biodegradation indicate fission of the PVA molecular chain during the incubation.
