Mucic acid production from poly-d-galacturonic acid by marine Trichoderma sp. LF328 transformants
| Strain | T2 | T3 | D-161646 |
|---|---|---|---|
| Lactose + poly-d-galacturonate | |||
| Mucic acid (g L−1) | 3.6 ± 0.1a | 2.9 ± 0.6a | 1.7 ± 0.0b |
| Conversion mucic acid/available d-galacturonic acid (g g−1) | 0.42 ± 0.01 | 0.34 ± 0.07 | 0.20 ± 0.01 |
| d-Xylose + poly-d-galacturonate | |||
| Mucic acid (g L−1) | 3.6a | 3.6 ± 0.2a | 0.1b |
| Conversion mucic acid/available d-galacturonic acid (g g−1) | 0.40 | 0.39 | 0.01 |
Trichoderma sp. LF328 transformants were grown in 24-well plates using poly-d-galacturonic acid as substrate and either lactose or d-xylose as co-substrate. T. reesei Δgar1 udh strain D-161646 was included as a positive control. Values are mean ± standard error of the mean for n = 2 (D-161646) or 3 biological replicates. Values for mucic acid concentration in the same row with the same superscript letter (a or b) did not differ significantly (p > 0.05)
