The viewpoint of energy support Microbial cells are the producers of the target-products (or desirable products) for industrial fermentation. It is necessary for microbial cells'growth and maintenance to be supported by bioenergy, which should be transformed by the apparatus of cells themselves from energy sources of other types. Thus. industrial fermentation manifests biological attribute1.
