ABSTRACT



The objective of the studies was to evaluate possibilities of petroleum oil biodegradation by free and immobilized cells of C. lipolytica. Immobilization was conducted in 2% sodium alginate coated/non-coated with 1.0% chitosane. The elimination process involved 94.1% of the total amount of introduced hydrocarbons in cultures containing free cells of C. lipolytica and 96.5% and 96.1% of hydrocarbons in cultures containing immobilized cells. Statistically significant differences were observed for the rate of hydrocarbon degradation. The remains of traced substratum were at the level of 5.1% and 5.4% in cultures with encapsulated yeasts whereas comparable amounts of petroleum hydrocarbons (4.9%) were detected on 21st day of the experiment.

Key words: cell immobilization, C. lipolytica, biodegradation of hydrocarbons.
