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
like hydrogen fueled car. However, although our interest in fuel cell is increasing, the stage of the development is still slight. To develop fuel cell technique as the core industry, we have to construct effective infrastructures from extraction to supply. So, in this project, our team has searched the fuel cell technique dividing into four parts ; extraction, storing, type, merits & demerits.
Ⅰ. Introduction of Study
1. Background of study
Although the name of 'QR code' was difficult to remember at first, the recognition rate of 'QR Code' is increasing day by day. As smart phones have become popular globally, various marketings which are using it have appeared. One of the typical marketings is QR code marketing. If QR code which is also called 2D barcode is scanned, it simpl
2. 2. Extraction
After the fermentation, the microorganisms(Alcaligenes latus) are filled with PHB in their body. These PHBs have to be separated from microorganisms to make final product. To separate PHBs from biomass, they are extracted from biomass by using solvent. These PHB extracted solvent will experience washing and drying process. After that, PHB can be precipitated as white powder.

vaporization : Heating on the anaerobic to produce H2-CO first order
combination gas.
pyrolysis : On vacuum condition, decompose bio mass by
exposing high-temp.
solvent, acid, base : Using the bio mass for cl
