Decolorization of Synthetic Dyes by Marine-Derived Fungi Isolated from Decaying Leaves of Rhizophora Spp

This study explores the potential of marine-derived fungi isolated from Rhizophora spp. as bioremediation agents for synthetic dye pollution. Four fungal strains (MF1, MF2, MF3, and MF4) were isolated from different locations (Manila Marina Baytown Access Road, Boac, Marinduque Province, and Kaingin, Cavite, Philippines), exhibited decolorization of synthetic dyes (Methylene Blue, Congo Red, and Safranin). and tested for their ability to decolorize synthetic dyes (Methylene Blue, Congo Red, and Safranin). The results showed that Methylene Blue was the easiest to decolorize, while Safranin was the most resistant. Safranin proved to be the hardest to decolorize, while methylene blue was the easiest, appearing decolorized after two days of incubation. Exoenzyme tests revealed that the fungi produced amylase, xylose isomerase, and cellulase, suggesting their potential in dye degradation.
