Changes in the Tricarboxylic acid Cycle Acids in Potatoes After Anaerobiosis

Abstract

Potatoes were subjected to anaerobiosis and then returned to air. Citrate was estimated in three experiments and malate in one. Citrate increased slightly in air after nitrogen in two experiments but not in the third. There was also a small increase in malate. From these results no firm conclusion was drawn as to whether the turnover rate in the tricarboxylic acid cycle had increased. However, the lost lactate which was unaccounted for as increased CO. output during recovery from anaerobiosis was less than the observed increases in citrate and malate contents in two experiments.
