摘要
在加氨条件下对玉米秸秆进行了汽爆处理(简称氨化汽爆)和固态发酵. 结果表明: 氨化汽爆同样可使秸秆中的半纤维素降解，并使玉米秸秆的酶解率提高到42.97%, 同时可使秸秆的有机氮含量提高1.27倍. 利用氨化汽爆秸秆进行固态发酵，可提高蛋白含量到23.45%，比不加氨汽爆的玉米秸秆提高了1倍. 而加过氧化氢的氨化汽爆不利于微生物发酵.
Corn straw was ammoniated and steam-exploded. This pretreatment resulted in degradation of hemicellul- ose and less degradation of cellulose and lignin. In addition, substrate hydrolysis was enhanced, the content of nitrogen was increased. After solid state fermentation of pretreated corn straw, the content of protein was increased and the content of cellulose was reduced. Steam-explosion of ammoniated corn straw is suitable for bioconversion.
