Expansion of growth substrate range in Pseudomonas putida F1 by mutations in both cymR and todS, which recruit a ring-fission hydrolase CmtE and induce the tod catabolic operon, respectively.

Abstract excerpt

Pseudomonas putida F1 can assimilate benzene, toluene and ethylbenzene using the toluene degradation pathway, and can also utilize p-cymene via p-cumate using the p-cymene and p-cumate catabolic pathways. In the present study, P. putida F1 strains were isolated that were adapted to assimilate new substrates such as n-propylbenzene, n-butylbenzene, cumene and biphenyl, and the molecular mechanisms of genetic...
