The lipolytic bacterium Pseudomonas fluorescens was cultivated in nutrient broth supplemented either with olive oil, sunflower oil or soybean oil. Presence of oil delayed bacterial growth and lipase production, but the finally obtained cell density and amount of lipase was approximately the same as in unsupplemented nutrient broth. The lipase hydrolyzed soybean oil to a greater extent than olive oil and sunflower oil, respectively. Fatty acids were deteriorated into volatile compounds which were detected in the head‐space gas over the fat containing media. The volatile fraction was found to contain alcohols, aldehydes, ketones, esters, furans, sulphur compounds, and hydrocarbons.
