| Description |
The investigation was carried out with the objective of isolating ethanol tolerant yeast cultures with amylolytic activity and possessing ability to produce alcohol fermentatively from over ripened banana pulp. Several samples were obtained from different sites and isolates were purified among which three isolates were identified as yeast cultures based on morphological, cultural and biochemical characters. Among the three cultures none of the isolates had amylolytic activity. All the isolates showed tolerance to ethanol upto 8% and had alcohol producing ability. Highest alcohol production (88.10g/L) was noticed with Saccharomyces cerevisiae MTCC-172 among all the yeast cultures used. However, among the yeast isolates AMB-213 produced maximum alcohol content 51.17 g/L from the over ripened fruit pulp. Banana pulp was subjected to treatment with pectinase to increase the flowability of the pulp and also to increase availability of sugars, etc. for utilization by yeast culture for conversion to alcohol. The alcohol production was found to be less (51.17 g/L) by the local isolates when compared to the standard cultures, Saccharomyces cerevisiae MTCC-172 and NCIM-3095 available in the Department of Agricultural Microbiology & Bioenergy, College of Agriculture, Ranjendranagar. Based on the present study it is established that over ripened bananas pretreated with enzymes can be used effectively for fermentative production of alcohol by Saccharomyces cerevisiae MTCC-172. |
