Enzymatic modification of bleached softwood kraft fibres for improved fibre reactivity was studied at high (20% w/w) and low (1% w/w) dry matter content. The role of enzyme family and structure in fibre modification was assessed using endoglucanases

Fibres fractionated from solid recovered fuel (SRF), a standardised market combustion fuel produced from sorted waste, were considered as a source of lignocellulosic fermentable sugars. The fibre yield from four samples of SRF was 25-45%, and the sep

The FibreEtOH concept was developed to tackle major challenges in the production of ethanol from lignocellulosics. The two feedstocks, waste fibre fractionated from solid recovered fuel, and pulp and paper mill fibre sludge, provide all-year-round su

Publikováno v: Applied Biochemistry and Biotechnology. :195-204

To develop functional enzymes in cellulose hydrolysis at or above 70 degrees C the cellobiohydrolase (CBHI/Cel7A) of Thermoascus aurantiacus was cloned and expressed in Trichoderma reesei Rut-C30 under the strong cbh1 promoter. Cellulase production o

Fungal cellobiohydrolases from the glycosyl hydrolase family 7 are key enzymes in crystalline cellulose hydrolysis. Difficulties in heterologous expression in a bacterial or yeast host have hampered engineering of these cellulases for industrial appl
