Control of aerobic fermentation processes

摘要: Aerobic fermentation processes which involve mixing an aqueous microbial food medium with a culture are controlled by continuously withdrawing sample of the microorganism and mixture culture, directly measuring respiration rate both samples proportionating amount admixed in response to measured maintain ratio biochemical oxygen demand that at preselected constant value. This control process is preferably used when decomposing wastes such as sewage aerobic fermentation.
