Enzime recovery by ultrafiltration from broth

Abstract

Recycling waste products of food industry is important: one side because of the environmental aspects and the other side because of the economic reasons. The one of the most preferred basic material for second generation bio-fuels might be the tobacco (Ábel et al. 2011). The cost of the process depends on the cost of the hydrolysis of cellulose/lignocelluloses i.e. and the cost of the enzymes. These enzymes are very expensive and that is why it is so important to find a good enzyme recovery method. In my research the membrane separation was used for enzyme recovery. Different polyether-sulphone membranes with cut-off value of 7 kDa (PES7) and 10 kDa (PES10) were used for separation the hydrolyzate.
