Abstract: A Warburg study demonstrates the effects of low temperature, chloride ion concentration, and ultraviolet irradiated asphalt on the growth of activated sludge and sewage fungus Geotrichum candidum. An adverse environment resembling a salted snow melt gaining its way into a sewage treatment plant could make Geotrichum candidum highly competitive with sewage bacteria and could lead to the overgrowth of the fungus in activated sludge processes.
