Cellulases and Xylanases Production by Penicillium Echinulatum in Submerged Cultivation: Statistical Optimization of Process Parameters

Enhancing Thermal Stability of Immobilized Raw Starch Digesting Amylase (RSDA) Using Different Additives

The present work investigated the use of sorbitol as a soluble carbon source, in association with cellulose, to produce cellulases and xylanases in submerged cultures of Penicillium echinulatum 9A02S1. The production of cellulases and xylanases is difficult in submerged cultures, because the cellulose used as an inducing substrate is insoluble, which causes rheological difficulties, such as homogenization of the medium, aeration and agitation, factors that influence the oxygen transfer.
