Extracellular Enzymatic Activities of Bacteria | Microbial Biotechnology
Article shared by :
In this article we will discuss about the extracellular enzymatic activities of bacteria: 1. Starch Hydrolysis 2. Lipid Hydrolysis 3. Gelatin Hydrolysis 4. Casein Hydrolysis. 1. Starch Hydrolysis: Starch is composed of glucose molecules linked together by glucosidic bonds. This is hydrolysed by amylase into dextrins and then maltose. Maltose, a disaccharide is finally hydrolysed […]

Article shared by :
In this article we will discuss about the principle, requirements and procedure for identification of unknown bacterium. Principle: For this the bacteria are first observed for morphological characters like size, shape motility, etc. and then separate them based on Gram staining into Gram-positive and Gram- negative ones. Further, the biochemical characters are observed. Requirements: 1. […]
