Penicillium ludwigii


P. ludwigii is a drug-resistant, anamorphic fungus found in the environment (often sediment and soils), with one study even demonstrating the potential tolerance of a Brazilian isolate of the fungus to uranium exposure.


P. ludwigii is a close relative of P. janthinellum, both of which rarely cause infections in humans, and typically reside within soils, but the Penicillium genus as a whole can cause serious illness in immunocompromised patients.


Due to the copper-resistant nature of the fungus, P. ludwigii can be used as a challenging microorganism for copper sanitization studies. This fungus can be used to evaluate antimicrobial efficacy of a variety of products, particularly textiles and plastics.
