Effect of starvation on activity and viability of Pseudomonas aeruginosa ATCC 10145 degrading 4-chlorophenol.
The evolution of degradsation capacity and in the viability of Pseudomonas aeruginosa ATCC 10145 acclimated to 25 mg4CP/L degradation and, later, exposed to starvation periods of 24, 48, 72, 96, 132 and 156 hours was studied. Degradation rate heterotrophic plate count and cell cytometry were used to evaluate the starvation influence. Results demonstrated that the exposition of P. aeruginosa to starvation produces a decrease in the viability and activity for the degradation of 4-chlorophenol.
