The accumulation of solid human waste is a major problem for long-term space expeditions. Fungal bioremediation of human waste is a powerful solution to this problem. We report here the comparison of a variety of wild-type filamentous fungi for their ability to rapidly degrade solid waste. Certain strains of wild-type filamentous fungi, such a Neurospora crassa and Gelanispora cerealis, yielded waste to fungal-mass conversion rates of over 60 percent in seven days. Several strains, including Neurospora crassa, are edible and average about 50 percent amino acid content by mass, potentially providing a high-protein food generated in-flight to explorers of the final frontier.
