为资源化利用菊芋秸秆,以菊芋秸秆为底物进行了中温批式厌氧消化实验,通过对比不同浓度HCl和NaOH(0.2~0.8 mol/L)预处理对菊芋秸秆产甲烷潜力的影响,研究了HCl和NaOH预处理在菊芋秸秆厌氧消化中应用的可行性。研究结果表明:HCl处理效果优于NaOH处理,0.4 mol/L HCl处理后菊芋秸秆的产甲烷潜力达到了(229.57±13.77)mL/g,较未经处理的菊芋秸秆提高了71.17%;NaOH和HCl预处理均能够有效打开菊芋秸秆内部结构,其中HCl处理后,半纤维素降解率最大,为17.26%~31.75%,NaOH处理后,木质素降解率最大,为6.87%~16.87%;NaOH处理可以缩短菊芋秸秆的厌氧消化周期(T_(50),T_(80)和T_(90)分别缩短了5~6,9~14,5~11d),但要获得更大的甲烷产量可能需要更高浓度的NaOH进行预处理。综合考虑经济效益和对环境的污染等因素,低浓度的HCl更适于菊芋秸秆厌氧消化的预处理。

为提高青稞秸秆的综合利用率,选用KOH和NH_(3)·H_(2)O作为青稞秸秆固态预处理试剂进行中温批式厌氧发酵产甲烷试验研究,并通过Box-Behnken响应面法来考察不同含量的KOH、NH_(3)·H_(2)O及预处理时间对青稞秸秆累积甲烷产量的交互影响.结果表明:各因素对青稞秸秆累积甲烷产量的影响程度表现为NH_(3)·H_(2)O含量>KOH含量>预处理时间;通过响应面模型验证试验得到最优预处理条件为KOH含量5.13%、NH_(3)·H_(2)O含量3.35%、预处理时间13.87 h,该条件下累积甲烷产量实测值为282.34 mL/g(以VS计),与预测值(286.4 mL/g)非常接近,相对误差小于5%,证明验证模型有效.KOH和NH_(3)·H_(2)O联合预处理能够显著提高青稞秸秆厌氧发酵产甲烷能力(P<0.05),累积甲烷产量较7%KOH和5%NH_(3)·H_(2)O单一预处理及未处理分别提高了7.59%、20.82%和70.78%;二者联合预处理还能够有效降解木质素(降解率为29.21%),提高发酵液营养价值;同时,可减少回收预处理试剂的成本,降低对环境的污染.研究显示,Box-Behnken响应面法能较好地优化青稞秸秆厌氧发酵的预处理条件,KOH和NH_(3)·H_(2)O联合预处理是高效生产生物甲烷和环境友好的木质纤维素类废弃物的处理方法.

Inflammation underlies many chronic diseases， and inflammatory bowel disease (IBD) is a condition characterized by long-term inflammation of the gut. Egg whites have been shown to contain many beneficial active substances. Therefore， we obtained two peptides from salted egg white: Val-Val-His-Phe (VF-4) and Asp-Thr-Gln-Ala-Met-Pro-Phe-Arg (DR-8). The sodium dextran sulfate (DSS)-induced mice colitis model was used to evaluate its regulatory effect on colitis in vivo. The results showed that VF-4 and DR-8 improved the clinical symptoms of DSS-induced colitis， attenuated colon tissue damage， inhibited the activation of NF-κB/MAPK/PI3K-AKT signaling pathways， and inhibited the expression of inflammatory cytokines. 16S rRNA gene sequencing showed that VF-4 and DR-8 administration increased the relative abundance of intestinal beneficial bacteria including Lactobacillus， Blautia， and down-regulated the relative abundance of inflammation-related bacteria including Acinetobacter， Lachnospiraceae＿NK4A136＿group， Klebsiella. Moreover， the degree of correlation between pro-inflammatory cytokines and microbiota was as follows: IL-6 > TNF-α > IL-1β > IFN-γ. In conclusion， this study suggests that salted egg white peptides VF-4 and DR-8 have a significant anti-inflammatory effect in vivo. It also provides a strategy for the treatment of inflammatory bowel disease and a new way for the high-value utilization of salted egg white.

为提高青稞秸秆的综合利用率,采用NaOH对青稞秸秆进行预处理,研究不同水平NaOH和预处理时间对青稞秸秆厌氧发酵性能的影响,探讨NaOH在青稞秸秆厌氧发酵中应用的可行性。结果表明,与未经处理的青稞秸秆相比,NaOH预处理可以显著提高青稞秸秆产甲烷性能(P<0.05),且产气速率快、发酵周期短。其中,5%NaOH处理12 h青稞秸秆的累积甲烷产量高于多数木质纤维素类废弃物,为250.03 mL·g^(-1),是优良的发酵原料。NaOH预处理增加了青稞秸秆中纤维素含量(13.37%~39.31%),并有效降解了木质素(12.89%~64.34%)和半纤维素(0.96%~30.30%)含量。表明NaOH预处理是提高青稞秸秆厌氧发酵产甲烷性能的有效方法。
