Abstract
The study was focused on developing a continuous method to produce an alcohol mixture suitable to be used as a gasoline supplement The immobilized column reactor with wood pulp fibers was successfully used for the continuous production of butanol and isopropanol using Clostridium beijerinckii DSM 6423 A sugar mixture glucose mannose galactose arabinose and xylose representing lignocellulose hydrolysate was used as a substrate for the production of solvents The effect of dilution rate on solvent production was studied during continuous operation The maximum total solvent concentration of 1199 g/l was obtained at a dilution rate of 016 h−1 The maximum solvent productivity 558 g/l h was obtained at a dilution rate of 15 h−1 The maximum solvent yield of 045 g/g from sugar mixture was observed at 025 h−1 The system will be further used for the solvent production using wood hydrolysate as a substrateThis study belongs to the project of Commodity Chemicals from Forest Biomass–Bioforest which is part of the Biorefine–technology program financed by Tekes The Finnish Funding Agency for Technology and Innovation Finland In addition the financial support from industrial collaborators is greatly acknowledged
