Conifer and birch pulp fermentation to hydrogen and methane was studied using dry and wet pulps with a compost … enrichment culture at a pH range from 6 to 9. Hydrogen was produced at each pH, whilst methane was produced at all other pH … values except pH 6 with dry conifer pulp and pH 9. Hydrogen and methane yields were generally higher with birch than with …
