day 1 and slowly between days 2 and 3 when the enzymatic
hydrolysis temperature was 50 C. After 3 d, the reducing sugar
content leveled off, which may be attributed to the product inhibition.
The cellulase enzyme showed maximum hydrolysis activity at
45–50 C on the 3rd day (Fig. 4b). These results suggest that enzymatic
hydrolysis of rice straw by lignocellulose degrading enzymes
in-situ can be completed at 50 C in 3 d. The analysis of the rice
Will see that on day 3 have the high sugar content and After 3 d, the sugar content constant,
so the optimum of saccharification time is 3 d.
