Quizplus · Accepted Answer

Penicillium chrysogenum is the first penicillin-producing fungus that could be grown in stirred fermenters. This strain was originally isolated from a moldy cantaloupe in Peoria, Illinois and was found to produce higher yields of penicillin than P. notatum, which was previously the primary source of penicillin production. Aspergillus niger and Pisolithus tinctorius are not known for producing penicillin.
