TABLE 2.
Yields (in Cmol (Cmol galacturonate)–1, unless stated otherwise) and biomass- specific conversion rates (q; mmol gx–1 h–1) of anaerobic, galacturonate-limited chemostat enrichment cultures dominated by “Ca. Galacturonibacter soehngenii.”
| Yield (Cmoli Cmols–1) | Biomass specific conversion rates (mmol (gx) –1 h–1) | |
| D-galacturonate | – | −4.0 ± 0.2 |
| Biomass | 0.17 ± 0.02 | – |
| Acetate | 0.57 ± 0.03 | 6.9 ± 0.4 |
| Formate | 0.02 ± 0.01 | 0.4 ± 0.2 |
| CO2 | 0.18 ± 0.02 | 4.3 ± 0.3 |
| H2 (mol Cmol–1) | 0.02 ± 0.01 | 0.2 ± 0.1 |
| H2 + Formate (mol Cmols–1) | 0.04 ± 0.02 | |
| Acetyl-CoA derivatives (mol Cmols–1) | 0.29 ± 0.02 |
Chemostat cultures were operated at dilution rate of 0.1 h–1, pH, 8 and at 30°C, with galacturonate the sole carbon-source. Data are presented as average ± mean deviations, derived from nine measurements each on duplicate steady-state enrichment cultures.
