Impacts of facility size and location decisions on ethanol production cost

Cellulosic ethanol has been identified as a promising alternative to fossil fuels to provide energy for the transportation sector. One of the obstacles cellulosic ethanol must overcome in order to contribute to transportation energy demand is the infrastructure required to produce and distribute the fuel. Given a nascent cellulosic ethanol industry, locating cellulosic ethanol refineries and cr...

Purification and biochemical properties of a thermostable, haloalkaline cellulase from Bacillus licheniformis AMF-07 and its application for hydrolysis of different cellulosic substrates to bioethanol production

A thermophilic strain AMF-07, hydrolyzing carboxymethylcellulose (CMC) was isolated from Kerman hot spring and was identified as Bacillus licheniformis based on 16S rRNA sequence homology. The carboxymethylcellulase (CMCase) enzyme produced by the B. licheniformis was purified by (NH4)2SO4 precipitation, ion exchange and gel filtration chromatography. The purified enzyme gave a single band on S...

Ultrasonic Vibration-assisted Pelleting of Cellulosic Biomass for Ethanol Manufacturing By

Both the U.S. and world economies have been depending on petroleum based liquid transportation fuels (such as gasoline, diesel, and jet fuels), which are finite and nonrenewable energy sources. Increasing demands and concerns for the reliable supply of liquid transportation fuels make it important to find alternative sources to petroleum based fuels. One such alternative is cellulosic ethanol. ...

Enzymatic hydrolysis of cellulosic biomass

technology was selected as a key area for biomass technology development in the 1980s, and the US Department of Energy (DOE) has actively supported the scale up of ethanol production since the Office of Alcohol Fuels was created in the DOE after the ‘energy crisis’ of the 1970s. Although biological conversion of cellulosic biomass to fuels and chemicals through enzymatic hydrolysis of cellulose...
