In addition, with increasingly restricted regulations or complete prohibitiononthe use of a number of chemical fumigants for insect and microbial control in food, irradiation is an effective alternative to
Abstract
Bioethanol is one ofthe 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 ofthe bioma
