Shortcomings of current process
1. Activated carbon adsorption
2. Direct combustion
3. Catalytic oxidation
4. Ozone oxidation
1. Inconsistent efficiency
Efficiency sharply drops when it works for long time.
It happens as nutrients for microorganisms are insufficient.
2. Unequal growth of microorganisms
Efficiency decreases, hard to handle when factors change suddenly
immobilization), reactor productivity와 product inhibition을 최소화하기 위한 추출(extractive)발효를 사용하는 등의 많은 기술적인 시도들이 있었다. 그런 많은 노력들에도 불구하고 결과는 좋지 않았다. 따라서 ABE 발효과정을 최적화하는 것이 이 산업의 오랜 목표라고 할 수 있다. 때문에 Clostridium tyrobutyricum 그리고 C
additional redox mediators, enzymes, which exibit redox properities and are able to directly exchange electrons with conducting materials, are applied.
Hemoproteins usually are able to exchange electrons directly with electrode.
Electron transfer proteins

ferrocytochrome-c, O2 oxidoreductase …

1-1. The Bacchus marketing mix (4ps)
1) Product
The Dong-a company put out the Bacchus for the first time which was a nutrition and tonic drink. After then, similar products like the Wonbi-d and the Gronsanbamond were produced rivalry. Most of the products were sold as a fatigue recover in the 60s and 70s concentrating on the blue color and common populatio
