Optimization of submerged culture for the production of naphthoquinones pigment by fusarium verticillioides
A locally isolated fungus genus, Fusarium verticillioides., was evaluated as a potential producer of naphthoquinone pigment. Five variable growth media (type of complex media, carbon source, nitrogen source, mineral salt and initial pH of the medium) were systematically manipulated in shake flask cu...
