Inhibitory effect of biosurfactant purified from probiotic yeast against biofilm producers

Abstract

Extracellular surface active agents are produced by microorganisms by reutilizing the accumulated waste or by the assimilation of low cost carbon sources or other renewable resources. Isolation, identification, and screening of probiotic yeast Saccharomyces cerevisiae to check for its ability to produce microbial surfactants was the primary angle in the present work. The second angle of the work was to study the inhibitory action of the purified biosurfactant against Candida and Bacillus biofilms or aggregates of microorganism that can adhere to inanimate objects, resulting in the spread of many infections.
