abstract = {Hydrogen, an emergent alternative energy vector to fossil fuels, can be produced sustainably
by fermentation of cellulose following hydrolysis. Fermentation feedstock was produced
hydrolytically using hot compressed water. The addition of CO2 enhanced hydrolysis by ~26% between
240 and 260  C with comparable hydrolysis products as obtained under N2 but at a 10  C lower
temperature. Co-production of inhibitory 5-hydromethyl furfural was mitigated via activated carbon
sorption, facilitating fermentative biohydrogen production from the hydrolysate by Escherichia coli.
Post-fermentation E. coli cells were recycled to biomanufacture supported Pd/Ru nanocatalyst to
up-convert liquid-extracted 5-HMF to 2,5-dimethyl furan, a precursor of ‘drop in’ liquid fuel, in
a one-pot reaction. This side stream up-valorisation mitigates against the high ‘parasitic’ energy
demand of cellulose bioenergy, potentially increasing process viability via the coupled generation of
two biofuels. This is discussed with respect to example data obtained via a hydrogen biotechnology
with catalytic side stream up-conversion from cellulose feedstock.},
