three times as much carbohydrate for fuel ethanol production (Comis‚ 2008). Ethanol production from fresh cassava roots using a low-temperature process was evaluated on a pilot-plant scale. The application of low-temperature cooking to cassava starch followed by a dual enzyme action resulted in an ethanol yield comparable to that of a traditional high-temperature cooking process. Pressurized distillation gave a satisfactory recovery efficiency of ethanol but was slightly lower than that obtained

The Effect of Ethanol on the Viability of Artemia salina as Environmental Indicators Biology 151 Laboratory ABSTRACT Artemia salina are used as environmental indicator species. They are used to test changes in their environment. A. salina is sensitive to toxins‚ temperature‚ and drugs. For the experiment‚ cysts were put into different amounts of ethanol alcohol and their viability was measured. The hypothesis used was if there is more ethanol alcohol‚ then the viability

UTILIZATION OF BANANA PEEL WASTE TO PRODUCE ETHANOL I Introduction Due to increasing demand for energy‚ renewable energy sources particularly waste products like banana peel waste can be utilized to produce ethanol‚ as the vitality of ethanol are well known in science world‚ besides the methods of producing it is incomplex and it can give big impact to the world. II Body A Ethanol is widely recognized these days as a very promising alternative source of energy (Low & Isserman

After reading Ethanol Madness in The Economics of Public Issues (Miller‚ Benjamin‚ & North)‚ most of America is not benefiting from the production of ethanol. The only ones benefiting from ethanol requirements are ethanol producers‚ farmers‚ Brazilian farmers and politicians. Congress and the United Sates government are both benefiting from the ethanol requirements and the import tariff on ethanol. In the chapter I learned that ethanol is not as renewable as it seems. It is an alternative to biofuel

Carbohydrate: Ethanol from Sucrose Abstract The purpose of this lab was to demonstrate the fermentation process of ethanol from the substrate sucrose. To make ethanol from sucrose two enzymes invertase and zymase were used. Vacuum filtration and fractional distillation were performed to get a more concentrated solution. The density of ethanol was .825 g/mL with a percent composition of 85% pure ethanol. Introduction

viscosity‚ high paste clarity‚ and high freeze- thaw stability‚ which are advantageous to many industries. Ethanol is generally produced by the fermentation of sugar‚ cellulose or converted starch and has along history. In Nigeria‚ local production of ethanol from maze‚ guinea corn‚ millet‚ cassava and cellulose is as old as the country itself. Apart from food and pharmaceutical uses‚ ethanol is finding itself alternative uses for biofuel in most of the developed world for the reasons: it is not poisonous

The Extraction of Bio-ethanol from Apple (Malus domesticus) and Banana (Musa accuminata Colla) Peelings through the Process of Fermentation and Distillation Abstract Apple (Malus domesticus) and banana (Musa accuminata Colla) peelings are common household waste products. This study sought to extract bioethanol from these two peelings and to compare which sample can produce more bioethanol. About 400 grams of apple and banana peeling was obtained from the 1 kilogram bought from the supermarket
