The organic acid composition of aseptically‐grown timothy grass ( Phleum pratense ) was examined. Changes in organic acids of the grass during incubation in small test tubes with and without the addition of lactic acid bacteria were studied. Malic acid, a major acid of the grass, was broken down during incubation mainly by the activity of bacterial enzymes. The amount of succinic acid was increased by the action of both plant and bacterial enzymes. Citric acid was not detected in the aseptically‐grown timothy grass but two unidentified acids formed a major part of the total organic acid fraction.
