  • Title: Localization of Polyvinyl Alcohol Oxidase Produced by a Bacterial Symbiont, Pseudomonas sp. Strain VM15C.
    Author: Shimao M, Nishimura Y, Kato N, Sakazawa C.
    Journal: Appl Environ Microbiol; 1985 Jan; 49(1):8-10. PubMed ID: 16346711.
    Abstract:
    An axenic culture of a polyvinyl alcohol (PVA)-degrading symbiont, Pseudomonas sp. strain VM15C, was established on PVA with a crude preparation of the growth factor (factor A) produced by the symbiotic partner Pseudomonas putida VM15A. An increase of factor A in the culture medium enhanced the cell-associated PVA oxidase activity as well as the growth rate, but decreased production of extracellular PVA oxidase. PVA oxidase in cells grown on PVA was present in the periplasmic space at a higher ratio than in cells grown on peptone. PVA degradation occurred rapidly with washed cells. PVA was also degraded by immobilized cells entrapped in agar gels.
