Three fermentation pathways for succinate production. The reductive TCA, oxidative TCA and glyoxylate shunt pathway were shown by solid, short dashed and long dashed arrows respectively. PYC, pyruvate carboxylase; MDH, malate dehydrogenase; FUMR, fumarase; FRD, fumarate reductase; CS, citrate synthase; ACO, aconitase; IDH, isocitrate dehydrogenase; −-KGDH, −-ketoglutarate; SCS, succinyl coenzyme A synthetase; ICL, isocitrate lyase; MS, malate synthase.
