Effect of CaCO 3 concentration of lactate production. Total concentration of lactate (g/l, ♦), lactate yield (g/g glucose consumed, ■), undissociated lactic acid (g/l, ▲), and pH (○) shown as a function of CaCO3 added (g/l) with the pdc1Δ ::LhLDH pdc2Δ ::LhLDH transformant (A) in YP+10% (w/v) and (B) in YNB+10% glucose medium after 144 h incubation at 30° C.
