沉积物微生物燃料电池（smfc）作为一种可再生能源正在被开发，以帮助环境修复和提供远程监测。但漫长的启动时间限制了它们作为可行的工业方法的使用。本研究选取了7个不同富营养化程度湖泊的沉积物样本，研究了初始沉积物特性（ISP）对smfc启动时间的影响。60天后，不同采样点的ISP对启动时间为7 ~ 21天的smfc有明显的影响。沉积物中有机质，特别是活性碳库和氮（有机和无机）含量与smfc启动时间密切相关。此外，脱氢酶活性和高通量测序显示，营养物富集沉积物中的微生物增加了有机物的降解，并产生了一些特殊的物种，如candidatus xiphinematobacterium，属于与电子转移相关的verrucomicrobiaphyla。这种主动控制可以通过加速启动和提高SMFC功率和生物催化性能来提高适用性。
Sediment microbial fuel cells (SMFCs) are being developed as a renewable power source to aid environmental remediation and provide remote monitoring. But long start-up times limit their use as a viable industrial approach. In this study, we sampled sediments from seven different levels of eutrophication lakes and investigated the effects of their initial sediment properties (ISP) on the start-up times of SMFCs. After 60 days, ISP showed a clear influence on SMFCs with start-up times ranging from 7 to 21 days at different sampling sites. Organic matter, especially the labile carbon pools and nitrogen (organic and inorganic) contents in sediment, were closely related to start-up times for the SMFCs. In addition, dehydrogenase activity and high-throughput sequencing revealed that microorganisms in the nutrient enrichment sediments increased organic matter degradation and produced special species such as genusCandidatus Xiphinematobacterthat belong to theVerrucomicrobiaphyla related to electron transfer. Such active control may improve applicability by accelerating start-up and enhancing SMFC power and bio-catalytic performance.
