SUMMARY
A number of morphological and reproductive similarities between members of the genus Dictyuchus and those of Achlya prompted the present study of enzyme activities of Dictyuchus monosporus. Specific activities of phosphofructokinase, aldolase, isocitrate dehydrogenase, malate dehydrogenase, cytochrome oxidase, glucose 6-phosphate dehydrogenase, 6-phosphogluconate dehydrogenase, lactate dehydrogenase, alcohol dehydrogenase, and catalase in Dictyuchus were determined. The activities found were in general comparable to those found in Achlya ambisexualis, with the exceptions of glucose 6-phosphate dehydrogenase and 6-phosphogluconate dehydrogenase, whose activities were considerably lower in Dictyuchus.
