Improved Cellulase Performance on Pulp and Paper Substrates

One of the important steps in developing the nascent Biorefinery industry is the co-optimisation of ligno-cellulosic substrates and the enzymes required for their conversion to simple sugars. Of the many potential substrates being worked on by process developers, by-products of wood processing are of particular interest as the infra-structure necessary for the biomass supply and even, in some cases, pre-treatment for Biorefinery use already exists in the wood processing industries. This work will present the results of our applications research to develop ligno-cellulolytic enzymes for such substrates. One major component has been our involvement in a French consortium of academic and industrial groups - including the Institut du Pin (Bordeaux), the Laboratory of Biotechnology & Bioprocessing (INSA, Toulouse) and Tembek - funded through ADEME1. We will present our enzyme performance results on a wide range of cellulosic fiber samples generated within this French Pulp & Paper project, focusing on the identification of important parameters affecting enzyme conversion.
