• 1. Several kinds of α-hydroxysulfonates, the bisulfite addition compounds of aldehydes and ketones, were found to inhibit the photosynthetic carbon dioxide fixation of the barley and wheat seedlings, tobacco leaf and Chlorella cells. Bisulfite addition compounds of glyoxal, glyoxylate and benzaldehyde were more effective in this respect than those of formaldehyde and acetaldehyde. 2. The presence of α-hydroxysulfonate causes and increase in ratios of ^<14>CO_2 incorporated in glycolate and alanine, and a decrease in incorporation in serine, malate, isocitrate and citrate. It was inferred that these changes are caused by the blocking of the formation of glyoxylate through inhibition of glycolic acid oxidase by the poison. 3. A reaction scheme was proposed to account for the above-stated results, and the bearing of these findings on the possible role of glycolic acid oxidase in the photosynthetic carbon dioxide fixation and in the formation of amino and organic acids was discussed.
