RESUMO
Selective culturing of pseudomonads that could degrade quinoline led to enrichment cultures and pure cultures with expanded substrate utilization and transformation capabilities for substituted quinolines in immobilized and batch cultures. Immobilized cells of the pseudomonad cultures rapidly transformed quinolines to hydroxyquinolines in bioreactors and were able to tolerate higher substrate concentrations compared with batch cultures. After prolonged incubation on a mixture of quinoline and 6-methylquinoline, a quinoline-degrading culture of Pseudomonas putida developed the ability to biodegrade 6-methylquinoline, which initially was resistant to microbial attack, as a sole source of carbon and energy. 6-Methylquinoline was also degraded in a nonaqueous solution by this strain of P. putida when a solution of 6-methylquinoline in decane was flowed through an immobilized-cell fixed-bed bioreactor.
