Frequentin, a secondary metabolite produced by Penicillium janthinellum, is influenced by environmental conditions such as cadmium nitrate and sodium chloride concentrations. In cadmium nitrate-free medium, P. janthinellum produces cyclopenin, carlosic acid, erythroskyrin, kojic acid, and patulin. At 100 ppm cadmium nitrate, it produces cyclopenin, carlosic acid, frequentin, and islandicin. In the presence of sodium chloride, frequentin is produced at 2% and 3% concentrations. These findings indicate that frequentin production is sensitive to specific environmental stressors, highlighting its potential variability under different growth conditions[1]. | [Definition]
