Comparison of unoptimized and Taguchi optimized SSF combinations with mixed pretreated wild grass.
| SSF combination | Substrate concentration (%, w v−1) and mode of SSF | Reducing sugar* (g L−1) | Ethanol yield (g of ethanol g of pretreated substrate−1) | Ethanol titre* (g L−1) |
| GH5 + GH43 + S. cerevisiae + C. shehatae (unoptimized) | 1% shake flask | | 0.228 | | GH5 + GH43 + S. cerevisiae + C. shehatae (Taguchi optimized) | 1% shake flask | | 0.304 | | GH5 + GH43 + S. cerevisiae + C. shehatae (Taguchi optimized) | 1% bioreactor | | 0.472 | |
