What does Penicillium mean?

Also know, is Penicillium good or bad?

Since Penicillium molds can cause food spoilage, they also present a health hazard when consumed. This is because some species of Penicillium produce toxic compounds known as mycotoxins. (9) These toxins make food inedible and dangerous. However, some Penicillium species are beneficial to humans.

Why is Penicillium important to humans?

1.1 Introduction. Penicillium is an important genus of phylum ascomycota, found in the natural environment as well as in food and drug production. Some members of the genus produce penicillin, a molecule used as an antibiotic that kills or stops the growth of certain kinds of bacteria inside the body.
