위 그림은 Oil Sands에 Bacteria를 넣어줌으로써 Bacteria가 oil과 water의 interface에서 oil을 degradation 할 수 있도록 해주는 것이다. Bacteria는 oil과 같은 hydrocarbon을 degrade시켜서 methane gas를 배출한다. Oil Sands가 전부 degradation되어 methane gas로 변하고 나면 우리는 단순히 이 천연가스를 뽑아내기만 하면 될 것이다. 이
method, we would analyze the reason Hite beer has been fallen. And, analyzing primary data and secondary data, we would suggest how Hite beer implements strategies and retakes top of beer market again.
Ⅱ. Research Method
First, utilizing a publication, a thesis, internet and so on, we arranged the present situation of each Hite beer and OB(Cass) beer company.
Second, to grasp prese
water, those free complex carbohydrates turned into fermentable sources through pre-treatment process - saccharification. Then, it can be changed ethanol form through fermentation by yeast or genetically engineered E.coli and we can produce biofuel from that ethanol. Now, the way of decreasing process and cost are studied from a few researchers. So we will show the whole process of the production
