Presently we are facing the energy crisis due to the over-exploitation of non-renewable energy sources and hence thinking of renewable energy sources to fulfill the present need of fuel become most essential. The assessment of the world's oil endowment has become a sensitive subject with many implications. Recently, scientists are more interested in the production of bio-ethanol that can be popularly used as cheapest fuel or gasoline enhancer. Use of corn, sugarcane and potato has been studied for the production of bio-ethanol. Also, lignocellulosic materials are used as promising feedstock. But, usage of these feedstock residues for the production of bio-ethanol is the matter of dispute because of their reasonable importance in human society and for ecological balance. The oceans are abundant of natural resources. Seaweeds can be non-ending good source of polysaccharides that may be efficient for bioethanol production.
Our bio-energy research group mainly focuses on the production of maximum amount of monosaccharide from the seaweeds that could be used for alcohol fermentation to get bio-ethanol. Isolating micro flora from the gut of seaweed dependent animals and use of these isolates for the degradation of seaweed cell wall components to release simple sugars is a point of basic interest. However, choosing potential microbes for the production of bio-ethanol from different monosaccharide residues at the large scale fermentation is a challenging task in future prospects.
Microorganisms produce different polysaccharidases for the catalytic degradation of polysaccharides present in the cell wall of seaweeds. We are more interested in the production of different polysaccharidases that may be encapsulated to bring faster and effective process of fermentation. We are especially concern with utilization of brown algae Laminaria that is most commonly found in Pohang Sea. Lastly, construction of bioreactor for the bio-ethanol production will open more changes in the scientific world to fulfill world's oil endowment.
