| 摘 要： | 目的]研究添加不同碳源对厌氧微生物产甲烷活性的影响。方法]以传统的连续流为培养方式,在中温(35℃)厌氧消化条件下,分别用有机酸(甲酸、乙酸、丙酸和丁酸)和葡萄糖为惟一碳源,测定SS、VSS、甲烷累积产量以及有机碳源分解的动力学,研究添加不同碳源对厌氧微生物产甲烷活性的影响。结果]结果表明,以葡萄糖为碳源,微生物活性明显高于以有机酸为基质,其分解基质的速度依次为:厌氧产甲烷(G lu)>厌氧产酸(G lu)>丁酸甲烷菌>乙酸甲烷菌>甲酸甲烷菌。结论]该研究结果为高效地产甲烷提供理论依据。

| Abstract: | Objective] The aim of this research was to study the effect of organic carbon resource on specific methanogenic activity of anaerobic microorganism.Method] A series of sequence cultures were conducted to study the activity of anaerobic microorganism with organic acids(formic acid,acetic acid,propionic acid,butyric acid) and glucose as substrates.SS,VSS,accumulative methane production and kinetics of substrates degradation were measured in the anaerobic test(35 ℃).Result] The results showed that activity of anaerobic microorganism with glucose was better than with organic acids;the order of substrates decompounded by anaerobic microorganism was methane(Glu)>acid(Glu)>methane bacterium(butyric acid)>methane bacterium(formic acid)>methane bacterium(propionic acid).Conclusion] This research will provide the theoretical references for producing methanogenic efficiently. |
