Figure 1.
Response of estimated fermented hexoses (FH) to metabolic hydrogen incorporated into CH4 ([2H]CH4). Individual responses are adjusted by their experiment effect (exp): (A) Batch cultures: y = 1186 (±44.6; p < 0.001) + exp (p < 0.001) + 0.11 (±0.068; p = 0.12) x + exp × x (p = 0.041); R2 = 0.94 (p < 0.001); (B) Continuous cultures: y = 24.4 (±0.82; p < 0.001) + exp (p < 0.001) + 0.16 (±0.033; p < 0.001) x; (R2 = 0.74; p < 0.001).
