Carbon Nanotube-AttachedGlucose Oxidase for Biofuel Cells
The carbon electrode coated with CNT–GOx composites
was applied as an anode in a model glucose/O2 biofuel cell
CNT-supported glucose oxidase (CNT–GOx) was examined in the presence of 1,4

What is Bioenergy?
Bioenergy is renewable energy made available from materials derived from biological sources. Biomass is any organic material which has stored sunlight in the form of chemical energy. As a fuel it may include wood, wood waste, straw, manure, sugarcane, and many other byproducts from a variety of agricultural processes.
So, Why do we produce Bioenergy?
One reason governments
methanogene은 혐기성 조건에서 생존 가능
Metanogene 은 크게 2종류
Hydrotropic
4H2 +CO2 ->CH4 + 2H2
Acetotrophic
CH3COO- H+-> CH4 + CO2

Integrated coal Gasification Combined Cycle (IGCC) power plant is the most environmentally friendly coal-fired power generation technology. Most importantly, coal gasification offers the immediate opportunity to generate power with near zero greenhouse gas emissions and the pathway to a future hydrogen economy.
Description
Coal gasification is the process of converting coal to a gaseous f

지구온난화 위기에 따라 신재생에너지 도입 등 온실가스 배출 감소 노력이 전 세계적으로 실천되고 있는 가운데 도서지역에 태양광 등 신재생에너지를 도입하는 방안을 모색하는 방안이 연구되고 있다. 에너지는 우리인간이 생존하고 있는 곳에 많은 편리함과 이로움을 주고 있다. 에너지
Biodiesel을 얻기 위해 microalgae 사용
Microalgae에서 Oil의 함량을 높여야 함
TAG의 함량을 높여야 함
1) TAG biosynthesis pathway 관련 효소를 유전자수준에서 control
2) Bioreactor로 algae의 생장속도와 이차대사산물생성속도를 조절

biofuel production, and it can be used not only for biodiesel production but also for bioethanol production. Bioethanol can be produced by starch from algae through hydrolyze, pre-treatment and fermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and water, those free complex carbohydrates turned into fermentable sources through pre-treatment process - saccharif

Six million dollars is a small amount in the gasoline market. The United States consumes well over 20 million barrels of oil a day. Replacing some of this oil with ethanol seem, so far, to be the most feasible solution to reducing the country’s dependence on petroleum.
Today, most cars on the road can use a mix of 10 percent ethanol and 90 percent gasoline. But the car industry is rapidly chan
