The machinery of antibiotic production by Penicillium chrysogenum PQ-96 is composed of co-located cytosolic and peroxisomal enzymes of the penicillin G biosynthesis pathway. Pexophagy and exocytosis should be currently considered as an alternative for penicillin G secretion from the mycelial cells. Penicillin G overproduction is a cellular detoxification process, protecting the mycelium from the toxicity of the antibiotic precursor.
