| 제목 | Dynamic Analysis of Medium-Chain Fatty Acids (MCFAs) Production and Microbial Communities by Frozen Storage of Anaerobic Sludge as an Inoculum |
| 초록 | C5-C8 MCFAs could be produced from waste water containing organic compounds by mixed microorganisms. The purpose of this study is to compare the production performance and microbial community according to the storage method (freeze-treatment) of the inoculum (sludge from waste water plant). The un-frozen sludge was injected into the reactor containing food waste of 100 g/L, anaerobically. The frozen sludge was pretreated under -70 ℃ during 7 day, after that, it was injected into the reactor. Un-frozen condition showed various carboxylic acids containing MCFAs even in initial phase, while the frozen condition produced limited MCFAs after production of short-chain fatty acids. The un-frozen condition showed enrichment of Lactobacillus and Megasphaera genus. While, in the frozen sludge, Lactobacillus, Eubacterium and Caproiciproducens genus were dominated as significant ratios. This analysis showed that microbial community for MCFA production can be changed by low temperature. |
