According to Der Spiegel:
The sonic waves of Mozart’s compositions, along with the addition of oxygen, spur micro-organisms to a higher performance in breaking down biosolids, Stucki explained. As a result, wastewater facilities will be able to save energy costs and decrease the amount of residual sludge, which is expensive to dispose of.

Remember I told you how the studies on fish and plants proved that you don’t have to have ears to benefit from listening to Mozart? If even microbes are more productive, why not you? Try a little Mozart every day and see what effect it has on you!
