A CO2 concentration of 10% inhibited growth. Similar growth patterns were observed when the fungus was grown on a medium supplemented with the fungicide carboxin, which inhibits succinate dehydrogenase. A high CO2 concentration (1 to 10%) or growth on carboxin-supplemented medium caused a decrease in succinate dehydrogenase activity and significant increases in isocitrate lyase, isocitrate dehydrogenase, malate synthase and malate dehydrogenase activities. Mycelium of S. rolfsii grown at a high CO2 concentration contained less glyoxylate, lipids and glycogen than mycelium grown in air. It is suggested that sclerotium formation in S. rolfsii requires a balanced supply of carbohydrate intermediates and energy., UL https://www.microbiologyresearch.org/content/journal/micro/10.1099/00221287-100-1-167
