Effect of cobalt on growth of M. austroafricanum IFP 2012
| Substratea | Growth rate (mg of biomass/h/liter)
|
|
|---|---|---|
| Without CoCl2 | With 1 mg of CoCl2 liter−1 | |
| Ethanol | 4.9 | 4.7 |
| Acetone | 2.2 | 2.2 |
| Isopropanol | 6.7 | 7.6 |
| HIBA | 4.9 | 10.3 |
| TBA | 2.6 | 14.4 |
a
Substrates were added at final concentrations of 5, 2, 3, 3, and 7 g/liter for ethanol, acetone, isopropanol, HIBA, and TBA, respectively, by using three successive equivalent additions. The initial OD600 was 0.05 in each trial, and growth was monitored by measuring the OD600 for 240 h.
