RESUMO
In a mixed continuous culture of Pseudomonas putida VM15A and Pseudomonas sp. strain VM15C with polyvinyl alcohol (PVA) as the sole source of carbon, growth of the PVA-degrading bacterium VM15C and, hence, PVA degradation were limited by the growth factor, pyrroloquinoline quinone, produced by VM15A. Feeding of a carbon source for VM15A, ethanol, with PVA enhanced pyrroloquinoline quinone production and caused increases in the VM15C population and PVA degradation in a mixed continuous culture. There was an optimum range for PVA degradation of the ethanol concentration, although pyrroloquinoline quinone concentrations in continuous mixed cultures increased with increasing ethanol concentration.
