Acetaldehyde is a platform chemical with a production volume of more than 1 Mt/a, but is chiefly synthesized from petrochemical feedstocks. We propose the fermentative conversion of glucose towards acetaldehyde via genetically modified S. cerevisiae. This allows for ethanol-free bioactaldehyde production. Exploiting the high volatility of the product, in situ gas stripping in an aerated reactor is inevitable and crucial due to the respiratory toxicity effects of the acetaldehyde overproduction. We devise a lab-scale setup for the recovery of the product from the off-gas. Water was chosen as a suitable solvent and the Henry coefficient of acetaldehyde in water was validated experimentally. Based on an experimentally verified capture efficiency of 75%, an acetaldehyde production rate of over 100 mg/g/h was reached in 200 mL lab-scale fermentations.
