Production, Purification And Antimicrobial Activity Of Biosurfactants From Saccharomyces Cerevisiae And Pseudomonas Aeruginosa

Chemical surfactants are highly toxic to the environment so the Biosurfactants have paying attention by many scientists because of their low toxicity, biodegradability and ecological acceptability. The aim of this present study is to produce the Biosurfactants from Saccharomyces cerevisiae and Pseudomonas aeruginosa and to check its antimicrobial activity against several bacterial (Such as Escherichia coli, Salmonella sp., Shigella sp., Listeria sp., Vibrio sp., and Staphylococcus aureus) and fungal (Such as, Aspergillus niger, Aspergillus flavus, Aspergillus nidulans, Aspergillus fumigates and Candida albicans) pathogens. The present study clearly demonstrated the antimicrobial effect of Biosurfactants synthesized by Saccharomyces cerevisiae and Pseudomonas aeruginosa by their inhibition zone against pathogens. The Biosurfactants synthesized by Pseudomonas aeruginosa have the highest ability of antimicrobial activity against all the tested microbial pathogens.
