Mozart's music is thought to stimulate the mind. But can it also stimulate microbes? A sewage treatment plant in the German town of Treuenbrietzen, about an hour’s drive from Berlin, is trying to find out. For the last two months, the plant has been treating its biomass-eating microbes to Mozart played on a special stereo system designed to replicate the vibrations and sounds of a performance in a concert hall. The thinking is that the sonic waves of Mozart, along with oxygen added in the treatment process, will spur the microbes to break down sewage more efficiently, saving money. Or, to put it clearly: There's no shit in this world that can't be overcome by Mozart's music.
