It was once popular to think that secondary metabolites were merely laboratory artifacts but today there is no doubt that secondary metabolites are natural products. Over 40% of filamentous fungi and actinomycetes produce antibiotics when they are freshly isolated from nature. In a survey of 111 coprophilous fungal...
