1. Chiral recognition on cellulases : The active sites of the enzymes are involved
Sammanfattning : Two cellobiohydrolases (CBH I and CBH II) and endoglucanase I (EG I) fromTrichoderma reesei, and CBH 58 from Phanerochaete chrysosporium were immobilized onsilica as chiral stationary phases (CSPs) in HPLC for enantioseparation of a group ofpharmaceutical compounds. CBH I and CBH 58 wore excellent chiral selectors for β-adrenergic blocking agents, whereas CBH II displayed good enantioselectivity for someother compounds The CBHs share the common feature that their active sites are located intunnels.

2. Ethanol from woodCellulase enzyme production
Sammanfattning : Conversion of biomass to liquid fuels, such as ethanol, has been investigated during the past decades. First due to the oil crisis of the 1970s and lately because of concerns about greenhouse effect, ethanol has been found to be a suitable substitute for gasoline in transportation. LÄS MER
3. Investigation of Modified Cellulose and Starch via Hydrolysis and Mass Spectrometry
Sammanfattning : Starches and celluloses can be chemically modified in order to affect their physiochemical properties. Modification of these carbohydrate polymers entails derivatising their free hydroxyl groups with functional groups. LÄS MER
4. The relation between the supramolecular structure of cellulose and its hydrolysability
Sammanfattning : The liberation of fermentable sugars from cellulosic biomass during enzymatic hydrolysis is often incomplete. One of the factors limiting the efficiency of enzymatic hydrolysis is the structural properties of cellulose. LÄS MER
