USE OF TYPE C AND D FERULOYL ESTERASES IN THE MANUFACTURE OF BIOFUELS

摘要

The use of an enzyme preparation comprising type C feruloyl esterase or type D feruloyl esterase in the manufacture of biofuels from plant cell wall materials. A method for manufacturing biofuels from plant cell wall materials by converting lignocellulosic materials in said plant cell walls to sugars suitable for use as a fermentation feedstock, which method comprises (i) contacting said plant cell wall material with an enzyme preparation comprising type C feruloyl esterase or type D feruloyl esterase and plant cell wall degrading enzymes and (ii) separating any soluble sugars therefrom for bioconversion to biofuel. A slurry prepared by converting lignocellulosic materials in plant cell walls to sugars using an enzyme preparation comprising type C feruloyl esterase or type D feruloyl esterase, and optionally plant cell-wall degrading enzymes.
