Description:
Biosurfactants are surface-active biomolecules that produced by bacteria or fungi. Yeast species were used targeted here for their non-pathogenic nature, eco-friendly and cost-effective manner. Given the industrial importance to biosurfactant production, the goal of study was to explore potential of yeasts having biosurfactant production capabilities. Considering the cell hydrophobicity seven isolates were selected, identified and production parameters were investigated. All the yeasts showed potentiality to produce biosurfactants based on the results of emulsification index, oil spreading capacity, surface tension reduction and foaming properties. All the yeasts were produced diverse types of fatty acid utilizing SL medium with 5% sunflower oil determined by Gas Chromatography. Biosurfactants were produced by the yeasts culture from 16.0±1.07 g/L by Candida shehatae to 29±0.72 g/L by Zygosaccharomyces bisporus. Based on these results, the isolated yeasts have a greater potential as candidates for mass-scale production of biosurfactants with effective compounds at low cost
