2 .Bidirectional hydrogenase
1) Definition of bidirectional hydrogenase
Unlike uptake hydrogenase, bidirectional hydrogenases are helpful in hydrogenproduction. The biological role of bidirectional hydrogenase is thought to control ion levels in the organism. Bidirectional hydrogenase is associated with the cytoplasmic membrane and likely
need
alternative energy
Hydrogen is one of well-known clean energy source.
Several technologies are already available in the marketplace for the industrial production of hydrogen.
Hydrogen can be produced from a variety of feedstocks.
A variety of process technologies can be used, including chemical, biological, electrolytic, photolytic and thermo-chemical
production, and it can be used not only for biodiesel production but also for bioethanol production. Bioethanol can be produced by starch from algae through hydrolyze, pre-treatment and fermentation process, After algae produce sugar or starch from carbon dioxide, sunlight and water, those free complex carbohydrates turned into fermentable sources through pre-treatment process - saccharification.
preservation technologies. Various modern technologies are applied to inhibit the growth of micro-organisms in food product as various food-spoilage micro-organisms are exit. Consequently, the techniques are so complicated and diverse to state in one paragraph. This report divides the methods into several categories, physical, biological, and chemical, and introduces each technology briefly.
