Abstract
The cell wall is based on lignocellulose, including three primordial components: cellulose, hemicellulose, and lignin. Enzymes of the glycosyl hydrolases kind act on this type of bond between cell wall components. For this reason, those enzymes became an important target for cell wall hydrolysis. The beta-galactosidase acts on bonds ²(1’4) between sugars of lactose. This enzyme is the ma…
