A new catalytic process for saccharification of lignocelluloses from wood, straw and other low value agricultural/forest products will be developed. The process will combine the catalytic power of enzymes with the high penetration power and the ability to act under more vigorous condition found for organic acids. Dedicated protocols will be developed for the most relevant materials, i.e. abundant agricultural waste with low value for other purposes. The efficiency of physical pretreatment (chopping, crushing, grinding) will be evaluated. The research work will be divided beteween Sweden and Tanzania: Model degradation experiments will be divided between Tanzania and Sweden and fermentation tests will mostly be carried out in Tanzania. PI:s will make mutual research visits in Sweden and Tanzania. Junior staff from Tanzania should initially carry out training and research in Sweden and thus transfer competence for more extensive work in Tanzania. The general principles for enzymatic degradation of lignocellulose are well known and the usefulness of organic acids is reported in literature and confirmed in our lab. The project will result in increased knowledge about technical scale lignocellulose saccharification and to added value products such as ethanol from agriculural residue. Another important impact is the strengthening of north-south collaboration, scientific training of junior staff and capacity building
