| Compound | Dosage (mg C · liter−1) | C in biomass (%)a | C in CO2 (%)b | Parent compound (%)c |
|---|---|---|---|---|
| Phenol | 10 | 15.9–24.5 | 23.9 | 0 |
| 1-Octanol | 10 | 7.3–27.4 | 31.9 | 0 |
| Methyl jasmonate | 10 | 2.6–5.1 | 22.2 | 0 |
| Myrcene | 10 | 4.0–6.6 | 4.91 | ND |
| Musk xylene | 10 | 0.66 ± 0.23 | −4.94 | 100d |
| No-carbon control | 0.20 ± 0.05 | ND |
a
Range of mean summed biomass at maximum observed community sizes calculated using CellCognize. Values in bold typeface are significantly different from those of the no-carbon control (paired two-tailed t test, n = 3, P < 0.05).
b
Maximum measured CO2 evolution by headspace within 28 days.
c
Minimum residual percentage of parent compound measured by gas chromatography (GC). ND, not determined.
d
As a percentage of total organic carbon analysis compared to that at t = 0.
