1. Enzyme assays for lignin–carbohydrate bond hydrolysis
Abstract : To identify, produce, and use enzymes, analytical methods known as enzyme assays are employed. Enzyme assays are based on analysing the changes brought about on a substrate by an enzyme under defined conditions. Assays are often based on simplified reactions acting as substitutes for the reaction of interest. READ MORE

2. Dietary fibre production from oat hulls
Abstract : The current threats of climate change connected to the unsustainable consumption of fossil resources paired with an increasing world population demands the exploration of alternative raw materials for the production of food, fuel and specialty chemicals. Agricultural waste streams present suitable sources due to their availability in large quantities at low costs without competing with current food production. READ MORE

3. Fungal cellulases: Study of hydrolytic properties of endoglucanases from Trichoderma reesei and Humicola insolens
Abstract : Cellulose is one of the most abundant biopolymers on earth. Several organisms degrade cellulose, one of the most studied is the fungus Trichoderma reesei which produces seven genetically different cellulases. READ MORE

4. Enzymatic conversion of β-mannans: Analysing, evaluating and modifying transglycosylation properties of glycoside hydrolases
Abstract : Retaining glycoside hydrolases are enzymes that catalyse the breakdown down of glycans through hydrolysis. Due to the double-replacement mechanism of the retaining glycoside hydrolases (GHs), which form an intermediate with part of the glycan covalently attached to the enzyme, some GHs are able to catalyse synthesis reactions called transglycosylation.

5. Enzymatic conversion of β-mannans through transglycosylation and hydrolysis : Synthesis of building blocks for novel biomaterials from renewables
Abstract : The major softwood hemicellulose is galactoglucomannan (GGM), an abundant polysaccharide which constitutes up to 25% of the dry weight of wood, much of which is discarded in current refinery practices. Among the enzymes responsible for the degradation of this hemicellulose are the β-mannanases. READ MORE
