Starch test microbiology

Starch is a complex polysaccharide found abundantly in plants and usually deposited in the form of large granules in the cytoplasm of the cell. Starch consists of 2 components—amylose and amylopectin, which are present in various amounts. The amylose consists of D-glucose units linked in a linear fashion by α … Visa mer Many bacteria produce extracellular enzymes used to catalyze chemical reactions outside of the cell. In this manner, nutrient … Visa mer
