The ethanol production rate was optimum in the pH range of 5.5±6.0, and an ethanol yield of 0.41±0.46 g/g
was obtained in these fermentations. Because of heterogeneity between wood hydrolyzate batches, ethanol production was found to
be in¯uenced by hydrolyzate composition, pH, acetate concentration, amount of cells, and recycling of cells. Published by Elsevier
