(Please refer to PDF attached below for detailed information). Challenges in today's design 1. Uniform oxygen supply to every cell in the media is difficult to achieve. 2. Proper agitation system is needed for uniform distribution of nutrients. Today, both sparger and agitator are used separately. Since, aerobic fermenters are being used in 30% cases, and the prime challenge in aerobic fermenters are air supply, so this challenge should be solved. The new design may handle this challenge far better than the conventional designs. The new concept. In new design, all other parts and design of bioreactor will be same as today. We will change only the design of sparger and agitator used today. There will be no separate sparger and agitators. there will be a a hollow pipe inside which air will be supplied, which ultimately reach to each part if reactor. The same hollow pipe will also act as agitator. It will keep on moving. In short, we can say that:- it will function as human lungs where aur is supplied thorough one opening but the ultimate surface area is incredibly high ( 400 m2 in lungs).
