5.3.7 Effect of carbon supplements Supplementation of sugars‚ which may act either as carbon sources or inducers‚greatly affect the growth of microorganism. In case of CMCase‚out of the supplemented sugars‚glucose‚sucrose‚maltose‚lactose‚wheatbran and CMC‚ wheat bran show maximum increase in enzyme production. On addition of glucose‚ maltose‚ lactose‚wheat bran and xylan‚ the maltose resulted in an increment in xylanase production (24.96 IU/ml) by SmF. An induction in the enzyme production/activity

often proteins‚ that accelerate specific chemical reactions by lowering the required activation energy necessary for that reaction to occur. One enzyme in particular‚ Acid Phosphatase‚ is a critical enzyme in our every day biological functions. Phosphorus plays a vital role in energy transfer and metabolic regulation and is an important component of phospholipids and nucleic acids. (Hiroshi‚ 2001‚ Cavigis‚ 2001) Furthermore‚ if molecules need less energy to react because of the lowered activation
