ETHANOL PRODUCATION FROM SWEET POTATO PEELS AND ITS CHARACTERIZATION

Abstract

Fossil fuels (petroleum and coal) are among the natural energy supplies that are being used up quickly and are only expected to be available for a short period of time. Bioethanol is the most promising of the various alternative is enrgy sources that can replace natural enrgy resources because it is biological and renewable, typically derived from energy crops like maize, sugarcane, cassava, and sweet potato as well as byproducts of agriculture and forestry. Alcohol known as bioethanol is created by fermenting and distilling different feedstock (such as sugar, starch, and cellulose). Which have undergone enzymatic or acid hydrolysis to become simple sugars. One of the most significant starchy crops, the sweet potato (Ipomoea balatas L.) has a short growth cycle (90– 120 days) and may grow in a variety of agro-climatic situations. The invention of a simultaneous saccharification and fermentation process is the most significant process advancement developed for the enzymatic hydrolysis of diverse starch-containing crops and biomass. By removing the separate (saccharification) reactor, this approach uses thermo tolerant are yeast strains to reduce the number of reactors required. More significantly, however preventing the issue of product removal brought on by the accumulation of enzymes such celosias and AMG, which stop starch breakdown. It contrast, it concurrently applies fermenting microorganisms and a scarifying enzyme (AMG). AMG processes starch into sugars, and the fermentative microbes then turn the carbohydrates into ethanol. In this study, the effects of time (incubation) on the enzymatic liquefaction and saccharification of sweet potatoes were examined. Additional emphasis was placed on the use of SSF in the ethanol production process using liquefied sweet potato starchy biomass.
