Production of Microbial Enzymes from Agroindustrial By‐products

Solid-State Fermentations of the Genus Aspergillus

“…The highest enzymatic yields were obtained with carbohydrate mixtures such as glucose, molasses, starch, and wheat bran. Recent studies have shown that wheat bran could be substituted by cassava fibrous waste residue (Budiatman and Lonsane, 1987), by pretreated lemon peel (Maldonado et ai., 1986), or by henequen pulp (Huitron et at., 1984). Since pectinases are inducible enzymes, it is necessary to supply the culture medium with a pectin source such as citrus peel, apple pomace, or sugar-bette cassettes.…”
