Table 4.
The amount of PHA synthesized by C. necator using 4 g/L PS conducted over a 48 h incubation period at 30 °C (150 rpm). ND = non-detected; CDW = cellular dry weight.
| Media | Average CDW (g/L) | Average PHA (g/L) | PHA (% w/w) |
|---|---|---|---|
| BSM only | 0.08 ± 0.06 | ND | ND |
| TSB only | 1.61 ± 0.60 | 0.38 ± 0.03 | 17% |
| PS0 + BSM | 0.08 ± 0.02 | ND | ND |
| PS0 + TSB | 1.33 ± 0.20 | 0.52 ± 0.05 | 39% |
| PS1 + TSB | 3.56 ± 0.02 | 1.72 ± 0.03 | 48% |
| PS2 + TSB | 3.04 ± 0.03 | 1.28 ± 0.02 | 42% |
| PS3 + TSB | 2.64 ± 0.04 | 0.96 ± 0.03 | 36% |
| PS4 + TSB | 3.96 * ± 0.05 | ND | ND |
* Dry biomass of PS4 experiments contained PS4 particles that could not be separated using filtration.
