Experimental design for optimization of fungal enzymatic complexes based on total gas yield.
| Enzymatic Complex | E2 (mL) | E4 (mL) | Total Gas Yield (mL 100 mL−1) |
|---|---|---|---|
| E2 | 40 | 0 | 115.0 ± 1.4 cd |
| E4 | 0 | 40 | 112.6 ± 0.8 d |
| E241 | 30 | 10 | 123.8 ± 3.1 b |
| E242 | 25 | 15 | 132.0 ± 1.1 a |
| E243 | 20 | 20 | 122.2 ± 0.3 b |
| E244 | 15 | 25 | 115.0 ± 1.4 cd |
| E245 | 10 | 30 | 117.8 ± 0.3 c |
E2 and E4 are fungal enzymes from A. terreus HJ2 and A. nidulans HJ4, respectively. E241 to E245 are mixtures of E2 and E4 with different ratios. Values are presented as means ± standard deviation (n = 3). Different superscript letters within the same column indicate significant differences between groups (p < 0.05) determined by Duncan’s multiple-range test.
