Hi, Pigment is a secondary metabolite produce by fungus on substrate, the color control by the pH of substrate that the fungal grown on.

Gagana suryavamshi l

Yes.. Sir.. It's secondary metabolite but I want to know why they produce colour pigmentation with secondary metabolite

Xabier Vázquez Campos

Production of many pigments is induced by stress. PDA is C-rich but deficient in most other nutrients. That's the reason it's also one of the most typical media for the induction of sporulation.

Thank you sir..
