Accepted 16 May‚ 2008 The ability of different yeast strains isolated from ripe banana peels to produce ethanol was investigated. Of the 8 isolates screened for their fermentation ability‚ 5 showed enhanced performance and

Design: Investigation of Fermentation Introduction Introduction Yeast (Saccharomyces)is a single-celled microorganism in the Fungi family. It anaerobically respires sugars to produce ATP‚ as well as the waste products ethanol and carbon dioxide gas. This process is known as fermentation. There are various factors that affect the rate at which yeast respires. Aim To investigate the effect of concentration of table salt (sodium chloride) on the rate of fermentation of sucrose using yeast‚ measured

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

Fermentation and affects it has on foods Fermentation is described as the transformative action of organisms and the metabolic change either anaerobic or aerobic processes converting energy needed to turn raw product to a finished fully fermented food. Fermenting food has become more popular because people are realizing that if it were not for fermenting as a collection of people we would be in trouble. Fermenting has been done for hundreds of years because if not for fermenting letting foods just

project is to study the rates of fermentation of the following fruit or vegetable juices. 1. i. Apple juice 2. ii. Carrot juice 1 INTRODUCTION Fermentation is the slow decomposition of complex organic compound into simpler compounds by the action of enzymes. Enzymes are complex organic compounds‚ generally proteins. Examples of fermentation are: souring of milk or curd‚ bread making‚ wine making and brewing. The word Fermentation has been derived from Latin (Ferver which

Ethanol Production Ethanol is the type of alcohol found in alcoholic drinks such as wine and beer. Its chemical formula is: C2H5OH. Glucose from plant material is converted into ethanol and carbon dioxide by fermentation. The enzymes found in yeast (single-celled fungi) are the natural catalysts that can make this process happen. Here is the word equation: Sugar → Ethanol + Carbon Dioxide

obesity percentages. Sucrose is the leading added sweetener in in the manufacture of foods in the Unites States and is the biggest source of fructose. Sucrose and high fructose corn syrup (HFCS) are metabolized identically and react the same way to insulin‚ leptin and ghrelin. Sucrose is indifferent from HFCS in causing obesity. Compared to glucose‚ sucrose is extracted directly from the liver while glucose goes directly to the bloodstream causing larger sugar spikes. HFCS and sucrose have an identical

Fermentation Fermentation is a natural process that has been going on in nature since before humans existed. For centuries we have been practicing food fermentation‚ knowingly or unknowingly. Every food culture in the world throughout history has been using fermentation in their food in some way. Bread making originated in Egypt 3500 years ago. Fermented drinks were being produced and consumed in Babylon(now Iraq) 7000 years ago. China is thought to be the birth place of fermented vegetables. A

The rate of fermentation is faster when there is more sucrose concentration because it means there is more glucose‚ which in return means more carbon dioxide production. The sucrose concentrations were 0%‚ 1%‚ 5%‚ and 10%. The 0% sucrose concentration is just normal‚ plain water. Yeast‚ a single celled eukaryotic fungi‚ was put into the solutions. It uses fermentation to make more carbon dioxide and alcohol. In the 0% solution‚ no carbon dioxide had been produced. At the start‚ the depth of the

Ethanol What is Ethanol? Ethanol‚ which is sometimes called ethyl alcohol‚ pure alcohol‚ or grain alcohol is defined as‚ “a high octane‚ clean burning‚ American- made renewable fuels.” Ethanol is an increasing important aspect of our society and its popularity is becoming more widespread on a daily basis. Ethanol‚ a substance made out of Sugar-cane‚ maize‚ sorghum‚ wheat ‚ and other grains‚ has become one of the main viable source of energy in the world. In countries like South
