Archiv für Mikrobiologie Aims and scope Submit manuscript

Summary

A new cellulase producing species of penicillium, named Penicillium iriense, has been isolated. Cultures of this fungus in liquid media containing cellulose as carbon source. excrete into the medium an enzyme complex able to degrade both soluble and insoluble forms of cellulose. This complex has been separated into five protein fractions. Three of them are endowed with CM-cellulase activity, one contains a cellobiase and one contains a C1-like factor. These fractions show a moderate synergism in the attack of cotton fibres.
