Summary
Furfural as a product from thermic wood hydrolysis processes may be inhibitory to growth and fermentation of yeast cells. In order to determine the influence on the aerobic growth of the yeastPichia stipitis, expermiments were conducted in stirred reactors with the addition of furfural.
We found that the added furfural was rapidly reduced to furfuryl alcohol. Furfural inhibited the respiration and the produced furfuryl alcohol influenced the growth rate ofPichia stipitis. As a result from enzyme studies it can be concluded that the alcohol-dehydrogenase (ADH) was mainly responsible for the reduction of furfural to furfuryl alcohol.
