Název v původním jazyce

Novel aspects of symbiotic (polyvinyl alcohol) biodegradation

Popis výsledku v původním jazyce

A novel polyvinyl alcohol (PVA) degrading bacterium was isolated from activated sludge sampled during waste water treatment process and identified as Sphingomonas sp. Its PVA-oxidase activity and alcohol dehydrogenase activity for various low molecular weight secondary alcohols were detected. Both activities were associated with cells of the degrader and they were not extracellular. Under optimal conditions the isolate was able to degrade 500 mg of PVA per litre in two weeks. The strain required pyrroloquinoline quinone and another growth factor, the later supplied by co-isolated Rhodococcus erythropolis strain. The findings revealed a complex nature of the environmental PVA degradation and proved that other factor different from PQQ could be importantfor (in) biodegradation of the xenobiotic polymer with some sphingomonades.
