Bioprocess technology normally refers to the machinery and equipment in a biological products manufacturing facility where microbes such as yeast, bacteria, or fungi are used to produce a product by fermentation and/or enzymes to transform or modify a chemical or material to produce a final product. Bioprocess technology is also commonly integrated with conventional physical…
As most renewable energy and power companies know, power consumption during aerobic fermentation is one of the major operating costs. At any given point in the process, there are many combinations of airflow and agitation that will give the required mass transfer rate. But the combined power required of the agitator plus the compressor is…
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…
