4.1.2. Intermediates

A number of intermediate compounds synthesized by the microorganisms, algae, and green plants that act as store houses of biochemical energy. These intermediary compounds are utilized by the microorganism as well animals to produce the energy to fulfill their energy requirement for day to day activities. But using some specific microorganisms, as well as advanced technological strategies, these compounds can also be utilize for the production of a number of energy products such as gaseous hydrogen or methane, liquid ethanol or biodiesel, or solid dry biomass [36].
