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 PHBextracted solvent will experience washing and drying process. After that, PHB can be precipitated as white powder.
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%.
PHB Synthesis Pathway
Alcaligenes eutrophus PHB in normal circ
from propylene.
After several processes.
Products we have are 40% of acetone and water solution.
How we get nearly pure acetone?
Factors to be considered:
Feasibility
Product value
Cost
Product quality
selectivity
Possible Process:
Distillation
Extraction
Extractive distillation
Extraction(1)+Distillation
Extraction(2)+Distillation
Mainly involved in separation process

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 fromextraction to supply. So, in this project, our team has searched the fuel cell technique dividing into four parts ; extraction, storing, type, merits & demerits.

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
Q1. What are the gains to Gulf shareholders from the takeover bid?
A. 현재 Gulf의 주주들이 할 수 있는 것은 proxy fight를 통해서 gulf management의 요청대로 gulf의 편을 들 수 있고, gulf investment group의 요구에 따라 gulf사의 요구를 거절할 수 있다. 현재 Gulf는 Mesa 와 Gulf Investment Group의 M&A 작전에 따라 총지분의 21%가량을 빼앗긴
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
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
