Cellulase is an enzyme produced by fungi, bacteria and other microscopic organisms. Production of cellulase by intestinal bacteria helps with the digestion of plant cellulose and other beta-glucans, which are indigestible by human enzymes 1. Cellulase derived from widely utilized fungi, such as Aspergillus niger and Trichoderma longibrachiatum, is approved for use as a food enzyme by the U.S. Food and Drug Administration (FDA) 2.
