Abstract

In this work, biosurfactant production by several yeast strains was evaluated using different culture media. The best results were obtained with the strain Wickerhamomyces anomalus CCMA 0358 growing in a culture medium containing glucose (1 g/L) and olive oil (20 g/L) as carbon sources. This strain produced 2.6 g of biosurfactant per liter after 24 hours of growth. The crude biosurfactant reduced the surface tension of water to values around 31 mN/m, and its critical micelle concentration was 0.9 mg/mL. This biosurfactant was characterized through mass spectrometry (MS), and nuclear magnetic r ...
