Abstract
Three fungal strains; namely, Aspergillus terreus, Penicillium janthinellum and Penicillium duclauxii were cultured on different growth media including yeast extract, malt extract, yeast-malt extract, Czapek's Dox, Sabourod's, Harrlod's, and potato dextrose. The growth and secondary metabolites of the three fungal strains were greatly affected by the growth medium. The colour of the culture and secondary metabolites were noticeably altered and changed according to the growth medium used.
Key words: Growth medium, Aspergillus, Penicillium, Secondary metabolites, Culture characteristics.
