Abstrakt: The influence of the structure of C6 growth substrate on the activity of oxidoreductases and content of cytochromes b5 and P-450 in cells of Pseudomonas aeruginosa and P. fluorescens was studied. Among the hydrocarbons tested (hexane, 1-hexene, cyclohexene), 1-hexene was the most efficient inducer of the synthesis of cytochromes b5 and P-450 in log-phase cells of the pseudomonads. Substitution of the hydrocarbon substrate for a carbohydrate one (glucose) also resulted in a considerable increase in the activity of enzymes of the NADH-dependent electron-transport chain.
