Yeast for Biofuel Fermentation (P100004)

Yeast cells can metabolise fructose or glucose into ethanol using the well know pathways of fermentation (brewing). However the fructans found in some plant materials, i.e. fructose-polymers, cannot be digested by yeast cells without first being hydrolysised (broken down) using enzymes such as fructanase, an expensive additive to the process.

This invention describes a novel yeast cell with capability to metabolise fructans into ethanol directly, simplifying the process, improving yield (by 25%) and reducing production costs.

Patent applications are pending.
