Development of Low Cost Medium for Ethanol Production from Syngas by Clostridium Ragsdalei
(Oklahoma State University, 2012-12-01)
Gasification-syngas fermentation is a hybrid conversion technology on the verge of commercialization. Lignocellulosic biomass is gasified to synthesis gas, or syngas (CO, H2 and CO2) that is converted using biocatalysts ...
Effect of Switchgrass Maturity on Ethanol Production via Simultaneous Saccharification and Fermentation
(Oklahoma State University, 2014-05-01)
Switchgrass has been selected as a substrate to produce ethanol. One method of producing ethanol from switchgrass is through pretreatment followed by saccharification and fermentation. The harvest date of switchgrass could ...
Parameterization and Application of the Aquacrop Model for Simulating Bioenergy Crops in Oklahoma
(Oklahoma State University, 2012-07-01)
The objective of this study was to parameterize the AquaCrop model for two bioenergy crops, switchgrass and forage sorghum, using field measurements from Stillwater, Oklahoma in 2011. The parameterized model was then ...
Economic and Environmental Tradeoffs from Switchgrass and Ethanol Production (A Case in Oklahoma)
(Oklahoma State University, 2012-07-01)
In this study IMPLAN 2009 economic data, CEDA 4.41 environmental data and other data sources are used to determine the economic and environmental impact associated with switchgrass based ethanol production in Oklahoma. The ...
Economic Impacts of Land Use Changes Associated with Switchgrass-based Ethanol Production in Oklahoma
(Oklahoma State University, 2012-07-01)
Completed the requirements for the Master of Science in Agricultural Economics at Oklahoma State University, Stillwater, Oklahoma in May, 2012.Completed the requirements for the Bachelor of Arts in Agricultural Economics ...
Process Design and Economic Evaluation of an Ethanol Production Process by Biomass Gasification
(Oklahoma State University, 2010-12-01)
A large number of studies are being conducted on finding eco-friendly substitutes for petroleum-based fuels. Utilizing biomass as an energy source can significantly reduce dependency on petroleum, and the emission of ...
Effect of the Reducing Agent Dithiothreitol on Ethanol and Acetic Acid Production by Clostridium Strain P11
(Oklahoma State University, 2010-05-01)
The objective of this research is to investigate the effect of the reducing agent dithiothreitol (DTT) on enhancing ethanol production from synthesis gas (syngas) using Clostridium strain P11 in 250-mL serum bottles. ...
Simultaneous Saccharification and Fermentation of Switchgrass by Thermotolerant Kluyveromyces marxianus Imb3: Effect of Enzyme Loading, Temperature and Operating Mode
(Oklahoma State University, 2011-05-01)
The objectives of this research were to determine the optimum enzyme (Accellerase 1500, Genencor International, NY, USA) loading, temperature and operating modes (batch and fed-batch) on ethanol production by simultaneous ...
Ethanol Production from Syngas by Clostridium Strain P11 Using Corn Steep Liquor as a Nutrient Replacement
(Oklahoma State University, 2010-05-01)
The objective of this research is to evaluate corn steep liquor (CSL) as an inexpensive nutrient and substitute to yeast extract (YE) used in the conversion of synthesis gas (syngas) to ethanol. Syngas is primarily a mixture ...
