Cellulases multicomponent

Hemicellulases, similar to the cellulase complex, are seldom found in isolation but are usually present as part of a multicomponent system. 

Cellulases are found in fungi and bacteria. Of commercial interest are fungal enzymes from Aspergillus or Trichoderma and a few bacterial enzymes. They are either used as a multicomponent, which contain all enzyme types and are found in Trichoderma reesei (Hypocrea jecorina), or as a monocomponent enzyme product, which consists of only one of the three types of enzymes. The multicomponent enzyme preparations can be produced from a selected cellulose overproducing strain of the wild-type organism, whereas the monocomponent cellulases are mainly produced in recombinant production systems. 

Most enzymes for detergent formulations, which are produced by genetically modified microorganisms, are monocomponents, that is, only one enzyme protein contributes to the overall activity. In a few cases, like cellulases, the enzyme product can be a multicomponent mixture of several enzyme proteins. In these cases, the recovery process must be designed to ensure that the ratio between the enzyme proteins important for the application is maintained throughout the recovery process.
