Advantages of bio-ethanol
Economy
- Bio-ethanol can be a replacement for fossil fuels.
- Governments will become less reliant on foreign petroleum imports.
Environment
- It doesn’t add the greenhouse gas. The CO2 released bythe combustion of bio-ethanolis re-absorbed by agriculture for the bio-ethanol feedstock.
ethanol form through fermentation by yeast or genetically engineered E.coli and we can produce biofuel from that ethanol. Now, the way of decreasing processand cost are studied from a few researchers. So we will show the whole processofthe production of bioethanol from algae, and we suggest some solutions for reducing cost andtheprocess focused on starch storage in algae cultivation and ferm
of cellulosic ethanol which we are interested in(Figure 1). At the upstream, biomass harvest undergoes a pretreatment and cellulose hydrolysisby enzymes andthen fermented toethanol through the points. Theinitial contract for each course are as follows.

① pretreatment of raw material
Toincrease the effectiveness of fibrin degradation, pretreatment is
the proce of grains and sugar to higher levels inthe future. Furthermore, the economy oftheethanol production process from grains depends on the market for its by-product, i.e. distillers' dried grains with solubles (DDGS) as animal food, which may not expand like theethanol market inthe future. In addition tothe price, there is concern about damaging forests byincreasing farming area as a
the other ingredients, such as ligninand cellulose, which have the characteristics of hard and complex structures belonging tothe upstream process, the microorganisms intheprocessof saccharification isto be used effectively. End preprocessing preprocessing using a mechanical or chemical pretreatment processbythe saccharification process using acid hydrolysis using enzymes.
