Abstract
Acetaldehyde at above about 0.3 g/l inhibited yeast growth, suggesting that it may contribute to product inhibition in alcohol fermentations when present at high concentrations intracellularly. The toxic effect s of acetaldehyde and ethanol were not mutually reinforcing, acetaldeh yde appearing to alleviate slightly the effects of ethanol. In support of this, low concentrations of acetaldehyde greatly reduced the lag p hase in ethanol-containing medium and increased the specific growth ra te.
