Abstract
Bio-ethanol, is considered the cleanest fluid fuel, and can be a dependable substitution to non-renewable energy sources. The maturation of sugar parts of plant materials produces it. Due to their high sugar content and abundance of nutrients, berries are thought to be an excellent source of fermentation products. This examination saw how well the yeast "Saccharomyces cerevisiae" created ethanol from strawberries (Fragaria ananassa) in rehashed bunches. According to the findings, strawberry juice had a total sugar concentration of 41.87 g/l. The final bioethanol percentage, ethanol yield, and maximum productivity were, respectively, 6 g/l/h (g ethanol per liter of strawberry juice per hour), 35 g/l (g ethanol per liter of raspberry juice), and 7 g/l (g ethanol per liter of strawberry juice).
