The studies focused on the effect of the addition of low concentrations of glucose - a substrate that is readily subject to microbiological degradation, on the rate of biodégradation of petroleum products. Glucose in concentration 1% was introduced into mineral medium containing 3% crude oil, with or without bacterial inoculum. The rate of degradation of crude oil in the individual cultures was determined for 3 weeks. The degradation of petroleum products in liquid mineral medium reached 56% after 21 days of growth in the presence of 1% concentration of glucose. The introduction of bacteria that had been cultured earlier in the presence of petroleum products had an effect on hydrocarbon removal efficiency - in both the presence and absence of glucose, the percent reduction of crude oil was high, reaching 76 and 86, respectively, after 21 days.
