Why are molds not so bad?

A leftover food in the kitchen has turned into a hairy monster or you have itchy toes after your last swim. The sight of mold rarely makes you happy. Someone who does get totally happy at hearing the word mold is Prof. dr. Jan Colpaert of UHasselt. Fungi, he calls them. They come in handy! (And not just in the form of a delicious portobello burger on your plate)
