Can enzyme hydrolyze starch
WebMay 11, 2024 · To utilize starch, the organisms must have enzymes that catalyze the hydrolysis of the (1→4) glycosidic bonds found between the α- d -glucopyranose residues. Enzymes that are capable of catalyzing the hydrolysis of the α- d – (1→4) linkages are called amylases and are widely produced by plants, bacteria, and animals. WebCarolina Labsheets™. In this lab, students culture two bacteria on potato dextrose agar, which contains starch. When grown on potato dextrose agar, bacteria that can secrete amylase—an enzyme that hydrolyzes starch—create a zone around their colonies in which starch is absent. When the agar is flooded with iodine solution, most of the ...
