文摘

Succinic acid productivity starts to decrease with decreasing dissolved CO2 below an upper threshold. The decrease in productivity occurs at a constant flux distribution up to a lower CO2 threshold. Below the lower threshold, succinic acid yields decrease as flux shifts to C3 pathways. Ethanol formation increases with decreasing dissolved CO2 below the lower threshold.
