摘　　要：金属有机骨架材料化工应用是近年来的热点研究课题。但这类材料对生物发酵过程的影响研究报道很少。以大米发酵和Cu-BTC金属骨架材料为例,在发酵过程中加入酒曲(质量分数为0.5%)和Cu-BTC晶体,使用高效液相色谱(HPLC)检测发酵产物中的葡萄糖、乙醇和乳酸的浓度。实验发现,随着Cu-BTC加入量的增加,产物中葡萄糖、乙醇和乳酸的浓度均逐渐降低。此外,MOF-5材料也具有类似的效果。这说明水不稳定的Cu-BTC和MOF-5对于发酵过程有抑制作用。The application of metal-organic frameworks （MOFs） for chemical processing has become a hot topic now. However, few works can be found in the literature with the influence of MOFs on the bioprocesses in the environment. Cu-BTC MOF crystals were prepared and added into the fermentation process as a case study. A 0.5%（mass） rice leaven, which contains Rhizopus, a kind of microorganism used in rice wine production, was added to the rice. The product composition （glucose, ethanol and lactic acid） was analyzed by high performance liquid chromatography （HPLC）. With the increasing addition of Cu-BTC, the concentration of glucose, ethanol and lactic acid reduces, in contrast to normal fermentation process in the absence of Cu-BTC. Besides, MOF-5 also has similar effects on the fermentation process. Obviously, Cu-BTC and MOF-5 have a negative effect on the fermentation process.
