Heat Transfer Issues in Mechanically Agitated Fermenters? Aerobic fermentation generates a significant amount of heat, which must be removed to maintain a constant temperature. The main heat sources are metabolic heat generation, agitator power input, and compressor power input. Removing the heat is made more challenging by the fact that fermenters are operated at mild…
This is a PowerPoint by Lee Enterprises Expert, Dr. Doug Rivers, about the past, present and future of ethanol in the U.S. It discusses the history of ethanol, feedstocks currently used to produce ethanol, and the byproducts, as well as new ethanol developments.
Bio-processing may involve aerobic fermentation, whereas ethanol and chemicals from starches and lignocellulosic materials are generally anaerobic processes. Aerobic fermentation is a metabolic process by which cells metabolize sugars via fermentation in the presence of oxygen and occurs through the repression of normal respiratory metabolism. Aerobic fermentation occurs in the presence of oxygen. It usually…
