Symbiotic fungus from the nest play an important role in cellulose degradation, termite could obtain extrinsic cellulase for digesting the lignocellulose from food. The paper mainly compared the discrepance of cellulase activities from termites living different habit, and illustrated the secretion mechanism of cellulase in termite.

高等白蚁后肠缺乏原生动物，但其巢体上的共生真菌具丰富的纤维素酶，因此白蚁常通过取食巢体上的共生真菌来获得外源性纤维素酶，协助完成食物中纤维素的消化与吸收。

The results also showed that there was a synergistic effect between xylanase and cellulase in the enzymatic saccharification of lignocelluosic materials.

采用纤维素酶水解玉米秸秆，对纤维素的糖化进程及纤维素酶的作用机制进行了研究。

MCP could effectively delay the softening of climacteric fruit, such as Starking and Fuji apples and Feicheng peach, but as different fruits had different softening mechanism, the mechanism of 1-MCP inhibiting different fruit softening was different: in Starking apples, the key enzyme to the softening is endo-and exo-PG, while during Feicheng peach fruit softening, the key enzyme was EGase before the 20th d and endo-PG after 20th d during storage at 0℃. 1-MCP inhibited fruit softening mainly by inhibiting PG activity in Starking apple while in Feicheng peach, by inhibiting the activity of EGase in the earlier storage time and endo-PG in the latter time. It was also found that LOX accelerated the initiation of the softening and was regulated by ethylene and 1-MCP in apple and peach.

2.1-MCP能较好的延缓红星、富士和肥城桃等跃变型果实硬度的下降，但是不同品种/树种的果实软化机理不同，1-MCP抑制其软化的机理也不一致：在红星果实中，对软化起主要作用的酶一直为内切和外切两种PG，而在肥城桃软化过程中，前20d以纤维素酶活性起主要作用，20d后软化以内切PG为主。1-MCP主要通过抑制红星果实中PG酶活性来抑制果实硬度的下降；在肥城桃果实中，1-MCP通过抑制前期纤维素酶和后期内切PG活性，延缓了果实硬度的下降。

There are mass symbiotic bacteria and protozoans in the hindgut of lower termite, which could produce multiple cellulase for hydrolysing plant cellulose. But higher termite is devoid of protozoans in the hindgut.
