## Abstract Fumaric acid (FA) was produced from __Eucalyptus globulus__ wood by successive steps of hydrothermal processing (to solubilize hemicelluloses and to increase the susceptibility of solids to enzymatic hydrolysis), enzymatic hydrolysis and fermentation with __Rhizopus arrhizus__ DSM 5772.
L-Malic acid was produced efficiently from fumatic acid by Saccharomyces cerevisiae SHY2. The amount of L-malic acid produced increased with the increase in initial fumaric acid concentration (from 20 to 120 g/L). The average specific and volumetric production rates reached up to 0.708 g/gob and 2.7
