Small-scale battery-like microbial fuel cells are a promising alternative power source for future low-power electronics. Controllable microbial electrocatalytic activity in a miniaturized microbial fuel cell with unlimited biodegradable energy resources would enable simple power generation in various environmental settings. However, the short shelf-life of living biocatalysts, few ways to activate the stored biocatalysts, and extremely low electrocatalytic capabilities render the miniature microbial fuel cells unsuitable for practical use. In new research, heat-activated Bacillus subtilis spores are revolutionarily used as a dormant biocatalyst that can survive storage and rapidly germinate when exposed to special nutrients that are preloaded in the device.
