| Abstract: | This paper introduces a restoration technique for petroleum contaminated soil, and the molecular biology and biochemistry of the processes of hydrocarbon catabolism. The emphasis is placed on variability in both the regulation and clustering of alkane degradation genes, novel catalytic mechanisms, the genetics of PAH metabolism, changes in membrane architecture, and active uptake and efflux of hydrocarbons. Furthermore, we discuss a molecular approach and point out its significant potential in understanding the processes of hydrocarbon catabolism and in restoration techniques. |
