Several fermentation products are important commercially outside of the food industry. For example, chemical solvents such as acetone and butanol are produced during acetone-butanol-ethanol fermentation. Complex organic pharmaceutical compounds used in antibiotics (e.g., penicillin), vaccines, and vitamins are produced through mixed acid

2024/1/2/ · Bio-H 2 production using dark fermentative processes has known drawbacks, which include a low yield of H 2 due to metabolic fundamentals such as stabilization issues of oxidative-reductive reaction, weak disintegration and hydration abilities, and rapid intake by methanogens, homoacetogens, and sulfate-reducing

2017/1/6/ · Optimization of production medium is required to maximize the metabolite yield. This can be achieved by using a wide range of techniques from classical “one-factor

The whole fermentation process is executed inside a bioreactor (aseptic) made up of a blended flask and a system for air supply, consolidated with a facility for heat exchange, like water jackets and snake tubes. The use of impeller blades and sparger is done for the maintenance of the culture conditions.

2023/8/3/ · Stirrer glands and bearings. The most important factor of designing a fermenter is to maintain aseptic conditions inside the vessel. It is highly challenging in the case of pilot-scale fermenters. Therefore stirrer shafts are required. These stirrer shafts play an important role to seal the openings of a bioreactor.

Manure fermentation is a biological process that occurs under anaerobic conditions, which means in the absence of oxygen. The process involves the breakdown of organic matter by microorganisms into simpler compounds, mainly biogas, which is a mixture of methane and carbon dioxide. The fermentation process can be divided into four main stages
