Grassohol and fibrzymes
Conversion of high sugar grasses to alcohol based transport fuel' and 'Fibres to products using enzymes'

The Grassohol project which ran between April 2009 and September 2012 was concerned with the conversion of high sugar perennial ryegrass to alcohol based transport fuel. The objective was to develop the technology and provide underpinning science for the utilisation of forage grasses for economically viable fermentation to bioethanol, capable of pilot plant scale-up.


The Fibrzymes project, February 2010 - January 2012, was driving the development of novel cell wall degrading enzymes and enzyme formulations for use in the breakdown of grass fibre. The aim was to develop an enzyme mixture to maximise sugar release from the fibre component of grass. Following enzymic digestion, these sugars can be converted into bioethanol and other important chemicals by the use of micro-organisms.


Although the Grassohol and Fibrzymes projects have now finished, much of the information gained from the research is being utilised and developed as part of the BEACON project.


The Grassohol and Fibrzymes projects, led by Aberystwyth University (IBERS), were jointly sponsored by BBSRC, by Defra through the Renewable Materials LINK Programme,

and by European Regional Development Funding through the Welsh Assembly Government’s Academic Expertise for Business (A4B) Programme.
The project partners were: Aber Instruments, Alvan Blanch, Axium Process, Biocatalysts, Germinal Holdings, NFU, TMO Renewables and Wynnstay Group plc.
