Synthesis of Bio-ethanol from Corn Stalk by Fermentation Process
Ethanol synthesis from corn stalk through fermentation process was studied. The ethanol produced was studied by various enzymatic treatment temperature and different feedstock loading in term of weight. The result shows that the highest concentration of ethanol contained in the sample was 48.90% at enzymatic temperature of 50°C. The temperature for optimum enzyme treatment have been identified ...
متن کاملFeed ingredient Co-Products of ethanol Fermentation from Corn
Introduction Processing conditions prior to or after fermentation of corn to ethanol can greatly influence the quantity, quality, and nutritional composition of co-products. Most of the increase in ethanol production in the U.S. is expected to come from dry grind corn plants. Because of the large expected increase in distillers’ dry grains with solubles (DDGS) production, processing modificatio...
متن کاملContinuous high-solids corn liquefaction and fermentation with stripping of ethanol.
Removal of ethanol from the fermentor during fermentation can increase productivity and reduce the costs for dewatering the product and coproduct. One approach is to recycle the fermentor contents through a stripping column, where a non-condensable gas removes ethanol to a condenser. Previous research showed that this approach is feasible. Savings of $0.03 per gallon were predicted at 34% corn ...
متن کاملAmmonium Acceleration of Glycolysis in the Ethanol Fermentation in a High Corn System
A non-saccharified high stress corn mash system was used to study the acceleration of glycolysis in glucose ethanol fermentation by Saccharoniyces cerevisiae. It was found that the controlled addition of ammonium sulfate or ammonium chloride resulted in an accelerated glycolytic rate, independent of the final ethanol yield. Adding high levels of ammonium salt, however, resulted in decreased ext...
متن کاملIndustrial symbiosis: corn ethanol fermentation, hydrothermal carbonization, and anaerobic digestion.
The production of dry-grind corn ethanol results in the generation of intermediate products, thin and whole stillage, which require energy-intensive downstream processing for conversion into commercial animal feed products. Hydrothermal carbonization of thin and whole stillage coupled with anaerobic digestion was investigated as alternative processing methods that could benefit the industry. By...
