Pseudomonas sp. strain Y2 is a styrene-degrading bacterium, which initiates the catabolism of this compound via its transformation into phenylacetate by the sequential oxidation of the vinyl side chain. The styrene upper catabolic gene cluster (sty genes) had been localized in a 9.2-kb chromosomal region. This report describes the isolation, sequencing and analysis of an adjacent 20.5-kb chromosomal...
A new bacterial biosensor for styrene has been developed and characterized. A translational fusion of the lacZ gene to the sty promoter of Pseudomonas sp. strain Y2 has been inserted into miniTn5. Transposition of the recombinant transposon to the chromosome of Pseudomonas sp. strain Y2 resulted in a whole-cell biosensor able to detect and degrade styrene. In this biosensor, the endogenous StyS/StyR...
