Table 1 Enzymatic tannin removal from wheat straw at different concentration of tannase
From: Treatment of wheat straw using tannase and white-rot fungus to improve feed utilization by ruminants
Tannase concentration | Tannase activity, IU | Remaining tannin, g/100 g WS | Tannin degradation, % | Gallic acid produced, g/100 g WS |
|---|---|---|---|---|
Raw wheat straw (control) | 0.0 ± 0.00 | 3.60 ± 0.05 (100%) | 0.0 ± 0.00 | 0.0 ± 0.00 |
WS + tannase (0.1%) | 423 ± 11.6 | 1.80 ± 0.04 (50.3%) | 49.7 ± 0.99 | 1.5 ± 0.03 |
WS + tannase (0.2%) | 846 ± 27.5 | 1.02 ± 0.01 (28.3%) | 71.7 ± 1.79 | 2.2 ± 0.06 |
WS + tannase (0.3%) | 1269 ± 47.6 | 0.33 ± 0.002 (8.9%) | 91.1 ± 2.7 | 2.8 ± 0.09 |
