Mahua flowers are rich source of sugars and hence harbors natural yeast flora which brings about natural fermentation process by metabolizing sugars to alcohol. The current study was aimed at isolating wild yeasts from the mahua flowers and testing the strains to screen strains having high productivity and high tolerance characteristics. Total seven strains were isolated and after screening only three isolates were showed ethanol tolerance of and osmotolerance. The IL 2 tolerated 20% ethanol whereas IL 1 and IL 2 tolerated ethanol between 7 to 12%. All the strains preferred pH 5 for growth. Osmotic stress tolerance was carried out using varying concentrations of salt and sugar it was found that IL 2 is a better strain than IL 1 and IL 3 with regards to stress tolerance. These strains can therefore, be further explored to test their potential of producing ethanol which can be used as a Biofuel.
