摘要: Abstract The chief carbon dioxide-fixing system in a fumaric acid-producing strain of Rhizopus nigricans is an acetyl coenzyme A - dependent pyruvate carboxylase. This enzyme produced high levels during the period rapid glucose utilization, and precedes fumarate accumulation. It proposed that this principal anaplerotic CO2 fixing mechanism organism, its continued operation media after biosynthesis has ceased results production acid.
