Production of Ethanol from Immobilized Saccharomyces cerevisiae

Ethanol (also called ethyl alcohol, grain alcohol, drinking alcohol, or simply alcohol) is an organic chemical compound S. cerevisiae is the most employed yeast for ethanol production at the industrial level though ethanol is produced by an array of other yeasts, bacteria, and fungi. This paper reviews the current and nonmolecular trends in ethanol production using S. cerevisiae. Ethanol has been produced from a wide range of substrates such as molasses, starch-based substrate, sweet sorghum cane extract, lignocellulose, and other wastes The study was carried out on ethanol production from Immobilized Saccharomyces cerevisiae The immobilization was done with calcium chloride and sodium alginate the beads were formed. Fermentation was carried out for 7 to 8 days at 28°C then distillation was done and final ethanol produce was checked with an alcohol meter and ethanol produce was 13% from immobilized Saccharomyces cerevisiae. The process parameters optimized were substrate conc, pH, and urea conc. The values of the process parameters are 30% substrate conc, pH 4.5, and urea conc 0.5%.

Probiotics are live microorganisms which upon ingestion confer health benefits to the host and are widely applied for human and animal welfare. The present study reports the isolation of yeast cells from caterpillar frasses and its probiotic characterization. Out of four yeast cultures isolated, all found to be non-hemolytic and cultures designated as CV-I, CV-II CV-III and CV-IV showed good bile tolerance at 1.2%. These cultures possessed the ability to grow pH range of 1.5 – 10, exhibited auto-aggregation and co-aggregation capabilities, which are essential for growth in alimentary canal and reduction of pathogen adherence on the intestinal epithelial cells. All cultures exhibited good tolerance to temperature up to 42°C. Isolate CV-I showed wide range of antimicrobial activities against pathogenic bacteria and fungi. This study is the first report of isolation and characterization of probiotic yeast from caterpillar frass. The isolate CV-I has been identified as Saccharomyces cerevisiae by molecular methods. This culture is an ideal candidate for further probiotic exploration.
