Table 2 Enzyme levels (IU.(mg protein-1)) of key catabolic redox-dependent enzymes at steady states at different dilution rates, i.e. GAPDH, ADH, LDH and estimated activity (% of potential activity) of LDH (LDHv) under physiological conditions (Tables 3, 4) based on previously described kinetic model [23], of C. saccharolyticus cultures in the presence and absence of N2 sparging. Presented data is average of one biological and at least three technical replicates at a linear range.

From: Reassessment of hydrogen tolerance in Caldicellulosiruptor saccharolyticus
