Heterotrophs and Carbon Fixation

... can be seen in industrial fermentation of citric acid by Aspergillus niger . In order to produce citric acid, the CO2 produced from pyruvate decarboxylation is re-used again by combining it with another pyruvate to produce oxaloacetate (by the action of pyruvate carboxylase and PEP-carboxykinase ...

micro question

Could you guys help me with this micro question? Decarboxylation of an amino acid results in the evolution of carbon dioxide. Would a gas trap, such as that seen in the fermentation test, give us an accurate measurement of decarboxylation? this has ...
