① pretreatment of raw material
To increase the effectiveness of fibrin degradation, pretreatment is necessary. The purpose of pretreatment improves the efficiency of the reaction (hydrolysis) by converting cellulose and its chemical composition and physical form and especially improves the accessibility of the enzyme.

History of 막장 drama
After the drama "청춘의 덫" had been made, which is the beginning of 막장 drama, other 막장 drama, such as 인어아가씨, 하늘이시여, 내 남자의 여자, 조강지처 클럽, 아내의 유혹 and 꽃보다 남자 was made. In these days, 막장 drama has been made an issue of itself but it had existed long time ago before, and it is less simultaneous than
Alkaline lysis method
- 세포의 cell wall과 cell membrane을 부수고 DNA만을 분리하는 방법
- Chromosomal DNA 와 plasmid의 고유한 형태 구조 차이를 이용 !
; Chromosomal DNA - 상대적으로 size가 크고, double heilx
Plasmid - size가 작고, supercoiled 형태 -> pH에 변화에 의한 변성↓

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
