Fungi from mangrove forest and their potential for decolorization

Abstract

Abstract Role of mangrove forests has been elucidated from different aspects including culture, economic and environments, and potential microbes from mangrove area has been interested from different viewpoints. This study is to determine the diversity of fungi from mangrove forest and their ability to degrade dye. Fungi were isolated from mangrove water of Belawan, North Sumatera, and screened for their decolorization activity in Mineral Salt Medium Agar (MSMA) containing liquid dye waste at a concentration of 25%, 50%, 75%, and 100%. Five isolates, JPM 1, JPM 10, JPM 12, JPM 14 and JPM 15, of 23 purified isolates exhibited better growth response until the highest concentration of waste (100%). All isolates showed better decolorization activity under liquid culture condition. JPM 14 85.66% exhibited the highest decolorization activity after 30 days. Molecular identification of 5 potential isolates indicted that all belong to different species, namely Aspergillus niger (JPM 1), Aspergillus citrinoterreus (JPM 10), Fusarium oxysporum (JPM 12), Montagnula chromolaenicola (JPM 14) and Trichoderma lentiforme (JPM 15).
