Dextranase, Trichoderma reesei, glucan hydrolase, is often used in biochemical research. Dextranase can catalyze the hydrolysis of α-(1,6)-glucosidic bonds in dextran, and has a wide range of applications, such as food processing, sugar modification, agent preparation, and medicine for enhancing the activity of endocarditis antibiotics wait.

N-Acetylglycine is a minor constituent of numerous foods with no genotoxicity or acute toxicity. N-acetylglycine is used in biological research of peptidomimetics.
