Abstract:
The expression of the rpoS gene during PHA depolymerization was monitored in Pseudomonas oleovorans GPol and its mutant defective in PHA degradation by analyzing the tolerance to oxidative and thermal stresses and the RpoS intracellular content. An increase in the tolerance to H2O 2 and heat shock was observed coincidentally with PHA degradation. Western blotting experiments performed in carbon-starved cultures showed that the RpoS levels were higher in the wild type than in the mutant strain. Complementation of the phaZ mutation restores the wild-type RpoS levels. These results suggest a probable association between PHA depolymerization and the stress tolerance phenotype controlled by RpoS.
