There has been an increase in the demand for bio-ethanol from different countries‚ including the Philippines in response to the wide implementation of environment protection laws. Bio-ethanol is ethanol derived from biomass has provided a sustainable source of energy fuel for transportation without increasing environmental hazard( ganguly‚ Chattejee‚ Dey‚2011). Eichhornia

Scientist are source of ethanol to help the U.S. in their need of fuel. This is the reasons why the researchers decided to make biodiesel out of sweet potato (ipomea batatas) peel to test its feasibility in producing ethanol. ii General problem 1. How much sweet potato peel is needed to produced certain amount of biodiesel 2. Does the biodiesel

gaps in the membrane because the side chains bond with the ethanol to produce new hydrogen bonds which disrupts the original hydrogen bonds that maintain the protein structure. These gaps allow the release of relatively large molecules such as pigment to pass through the cell membrane. As well‚ Ethanol molecules are slightly negative causing bonds between amino acid chains‚ R-groups‚ to break hydrogen bonds and form bonds with the ethanol instead. Therefore‚ introducing larger gaps in the membrane

Fermentation of Carbohydrates: Ethanol from Sucrose Objective: To demonstrate a fermentation process‚ isolate the ethanol produced by fractional distillation‚ determine the composition of the ethanol solution recovered‚ and make stoichiometric and yield calculations. Procedures: Fermentation Weigh out 20.0 g of sucrose and place it into a 250-mL Erlenmeyer flask. Add 100 mL of water and gently shake until all the sucrose has dissolved. To this solution add 0.60 g of dipotassium hydrogen phosphate
