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
Shortcomings of current process
1. Activated carbon adsorption
2. Direct combustion
3. Catalytic oxidation
4. Ozone oxidation
1. Inconsistent efficiency
Efficiency sharply drops when it works for long time.
It happens as nutrients for microorganisms are insufficient.
2. Unequal growth of microorganisms
Efficiency decreases, hard to handle when factors change suddenly

1. Uptake Hydrogenase
1) Definition of Uptake Hydrogenase and Mechanism of Hydrogen Production
Uptake hydrogenases are Ni-Fe enzymes that catalyze the conversion of hydrogen gas to hydrogen ions and electrons. They are found in the heterocysts and not in the vegetative cells of nitrogen-fixing strains of cyanobacteria. They remove the hydrogen gas produced by nitrogenase when they carry o
The luminol is activated with an oxidant. Hydrogen peroxide solution and sodium hydroxide is
used as the activator. In the presence of an catalyst, the hydrogen peroxide is decomposed to form
oxygen and water. The iron in potassium ferricyanide is a catalyst for the reaction.
When luminol reacts with the sodium hydroxide, a dianion is formed. The oxygen produced from
the hydrogen peroxi
