Resumo: Yarrowia lipolytica is unique strictly aerobic yeast with the ability to efficiently degrade hydrophobic substrates such as n-alkenes, fatty acids, glycerol and oils. In the present work, a 2(4) full factorial design was used to investigate the influence of the independent variables of temperature, agitation, initial cell concentration and initial petroleum concentration on crude oil biodegradation. The results showed that all variables studied had significant effects on the biodegradation process. Temperature, agitation speed and initial cell concentration had positive effects, and initial petroleum concentration had a negative effect. Among the crude oil removal conditions studied, the best temperature and agitation conditions were 28ºC and 250 rpm, respectively.
