The production of bioethanol from diary cattle´s waste/manure using fermentation by saccharomyces cerevisiae

Abstract

The worldwide need for biofuels, specifically bioethanol, is consistently increasing due to significant growth in population and industrial development need for energy. Starch and sugar base bioethanol faces competition as a source of food and fodder for animals and humans, popular crops such as sugarcane, corn, and cassava fall short of meeting the worldwide requirement for ethanol production. There is currently growing interest in using animal manure as the primary source of biomass for producing bioethanol. Cattle excrement is plentiful, easily replenished, and cost effective. To achieve successful removal of lignin from lignocellulosic materials, it is necessary to use a pre-treatment method that boosts the production of sugars that can be easily fermented after hydrolysis. This enhancement in the overall process is crucial. Technological progress and the presence of cow manure as a viable substitute feedstock are responsible for the emergence of fermentation and saccharification. This fermentation technique helps decrease the overall expenses associated with the production of ethanol from glucose and various other types of sugars. This method of bioconversion includes pre-treatment, hydrolysis, fermentation and dehydration of biomass feedstocks to generate ethanol. Ethanol production from cow manure and this thesis describes the technology readily avail-able for this purpose.
