biopolymers such as nucleic acids and proteins that are essential for life.
Most commonly, the continuously linked backbone of a polymer used for the preparation of plastics consists mainly of carbon atoms. A simple example is polyethylene, whose repeating unit is based on ethylene monomer. However, other structures do exist; for example, elements such as silicon form familiar materials such as
Abstract
Bioethanol is one of the alternative sources of oil resources which received attention with biodiesel. Many countries produce bioethanol from food sources such as corn and sugarcane, but it causes food-energy conflicts and farmland problem. So it needs to focus on new biomass which is sustainable, renewable, cost-effective and do not occurred any conflicts. Algae are one of the bioma
PHB`s Separation & Purification
Target of this study conducted to obtain a purely material PHB purification process debris in the damaged cells, and to remove the remaining medium components. PHB has been removed during the refining process with just remove the present efficiency of the overall purification stayed in the 70-80%.

1. Introduction
세포가 커지면 부피에 대한 표면적의 증가비율이 작아진다. 즉, 생물학 교과서에 나와 있듯이, 세포는 각종 영양분을 받아들이고 노폐물을 배출하는 활동을 한다. 만약 세포의 부피가 커지면 그만큼 세포의 생존에 필요한 대사활동의 양이 많아지는데 표면적의 증가
