Biofuel Ethanol Production By Saccharomyces Bayanus, The Champagne Yeast, Kristen Miller
Biofuel Ethanol Production By Saccharomyces Bayanus, The Champagne Yeast, Kristen Miller
All Theses
The importance of biofuel ethanol is growing as the demand for clean, renewable fuels produced from non-food sources increases. The United States relies mainly on corn and the yeast Saccharomyces cerevisiae for the production of ethanol. A shift to cellulosic feedstocks, as the main source of biomass for ethanol production, would alleviate the pressure on farmers to produce corn for both the food industry and the ethanol industry. Example cellulosic feedstocks include switchgrass, sorghum, and canary grass. The cellulosic feedstocks are typically grown on land that cannot support economic food production, and thus lay unused.
For cellulosic feedstocks to be …

Determining The Global Maximum Biofuel Production Potential Without Conflicting With Food And Feed Consumption, Watcharapol Pumkaew
All Theses
This study tries to resolve the competition between food and biofuel by balancing the allocation between food and feed areas and biofuel areas for the entire world. The maximum energy production is calculated by determining the theoretical amount of energy that can be grown, once food and feed consumption is taken into account, based on the assumption that unprotected grass and woody lands and forest lands can be converted into cultivated lands. The total optimum land area for biofuel energy, 4,926.49 Mha, consists of corn, rapeseed, sugar beet, sugar cane, and grasses. When considering energy conversion efficiency, the maximum energy …
