摘要: The stabilization of fungal cellulases by spray drying, the thermal stability Penicillium occitanis and effect some additives were studied. We observed that CMCase activity presents a good at 50°C, even after 60 h incubation. On other hand, β-glucosidase was more sensitive (loss 50%) reacts on total activities (Filter paper activities). addition hydrophilic agents such as ethylene glycol, polyethylene glycol (PEG6000) enhanced enzyme activity. PEG Maltodextrin, another water decreasing agent, then tested during drying Pol6 cellulases. presence 1% allowed best recovery but had negative while Maltodextrin showed very positive stabilization.
