Comments P.145 right column bottom paragraph: "In the transferase reaction the higher group potential of butyryl CoA built up by the large flux through fatty acid synthesis is transferred to the acetyl CoA pool, the resulting steadystate concentration of "active acetate" is sufficient to allow for the necessary ATP regeneration. In growing C. kluyveri cultures, the levels of acetyl CoA and butyryl CoA are about the same (Table 12), indicating that the acetate CoA transferase activity in intact cells is capable of coupling the exergonic and the endergonic part of catabolism." P.146 right column top paragraph: "The physiological feasibility of regulation of hydrogen evolution by the acetyl CoA/CoA ratio as studied in C. kluyveri (refs 295, 651) and in C. pasteurianum (refs 292-294, 296) is supported by the content of CoA derivatives measured in growing C. kluyveri cells (Table 12)."
