Certain properties make microorganisms well suited for industrial processes. Microorganisms not only possess a broad variety of enzymes to make an array of chemical conversions possible, but they also have a relatively high metabolic activity that permits conversions to take place rapidly. In addition, they have a large surface area for quick absorption of nutrients, and release of end-products. Moreover, [...]
