Enzyme recycling in lignocellulosic biorefineries
The next step in the commercial production of ethanol from lignocellulosic biomass is to diversify the diversification of the process. To do this, hydrolysis of biomass carbohydrates is needed. However, there has been very few cases where the technologies have been upscaled and tested in industrial settings. This is mainly because of many difficulties with recycling of enzymes from the complex lignocellulose hydrolyzate at industrially relevant conditions. This review provides a comprehensive overview of the various methods for enzyme recovery and recycling, for example recycling of free enzymes, reabsorption to fresh material, recycling of solids, membrane filtration, and immobilization.
