fermentation by yeast or genetically engineered E.coli and we can produce biofuel from that ethanol. Now, the way of decreasing process and cost are studied from a few researchers. So we will show the whole process of the production of bioethanol from algae, and we suggest some solutions for reducing cost and the process focused on starch storage in algae cultivation and fermentation process.
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.
8. 기상이 이상기체라 가정하고 염소 흡수장치에 들어있는 염소의 질량(kg)을 추정하라. (Hint: 슬러리 임의 질량을 basis로 하여 기준량의 슬러리가 점유하는 부피와 그속에 들어 있는 염소 질량을 계산한 뒤 문제 8에서 계산한 슬러리 실제 부피로 환산하고 기상에 존재하는 염소량을 추가한다.)

- Science : materials development, including creation of an advanced catalyst, a highly stable electrolyte, and efficient stabilization of the lithium anode metal.
- Engineering : development of high-porosity gas diffusion electrodes, ways of deopositing the catalyst onto the cathode and developing a membrane to prevent oxygen crossover to the lithium anode.
solution-phase reaction of Au nanoparticles with organic dithiols leading to the self-assembly of cross-linked nanonetworked with nanometallic electronic conductivity has been reported in a previous communication. Bard and co-workers have extended this method for the fabrication of self- assembled spherical ultramicroelectrodes by confining the self-assembly process to the tip end of a quartz mic
