Abstract
ZINC toxicity is known to reduce the levels of the hæm enzymes cytochrome oxidase and catalase in the rat1 and in the larvæ of the rice moth Corcyra cephalonica2. This communication reports observations made on cytochrome oxidase levels in and fermentation by Saccharomyces carlsbergensis after growth in media containing toxic concentrations of ionic zinc.
