Phylloremediation of Polyaromatic Hydrocarbons by Endophytic Fungi in Tea Leaves

Phylloremediation of Polyaromatic Hydrocarbons by Endophytic Fungi in Tea Leaves

discovered that Polyaromatic hydrocarbons (PAHs) including anthracene, and pyrene are highly caricinogenic and cause many health issues. They are released to the atamosphere from vehicular emissions and oil refineries and deposit on many plant surfaces. Tea phyllosphere harbours a variety of endophytes that are highly effective at degrading polyaromatic hydrocarbons, anthracene, and pyrene. Therefore the present research component was carried out with an attempt to analyse the pyrene and anthracene degrading capabilities of phyllosphere endophytic fungi that inhabit 𝘊𝘢𝘮𝘦𝘭𝘭𝘪𝘢 𝘴𝘪𝘯𝘦𝘯𝘴𝘪𝘴 (L.) Kuntze leaves. The best pyrene and anthracene degrading fungal strains were selected based on the High-Performance Liquid Chromatography (HPLC) results, and further kinetic assays. Light microscopy and SEM observations highlighted a heterogeneous endophytic fungal distribution among leaf tissue layers. 𝘗𝘩𝘺𝘭𝘭𝘰𝘴𝘵𝘪𝘤𝘵𝘢 𝘤𝘢𝘱𝘪𝘵𝘢𝘭𝘦𝘯𝘴𝘪𝘴, 𝘊𝘰𝘭𝘭𝘦𝘵𝘰𝘵𝘳𝘪𝘤𝘩𝘶𝘮 𝘨𝘭𝘰𝘦𝘰𝘴𝘱𝘰𝘳𝘪𝘰𝘪𝘥𝘦𝘴, 𝘊𝘰𝘭𝘭𝘦𝘵𝘰𝘵𝘳𝘪𝘤𝘩𝘶𝘮 𝘴𝘪𝘢𝘮𝘦𝘯𝘴𝘦, 𝘗𝘴𝘦𝘶𝘥𝘰𝘱𝘦𝘴𝘵𝘢𝘭𝘰𝘵𝘪𝘰𝘱𝘴𝘪𝘴 𝘤𝘩𝘪𝘯𝘦𝘯𝘴𝘪𝘴, and 𝘋𝘢𝘭𝘥𝘪𝘯𝘪𝘢 𝘦𝘴𝘤𝘩𝘴𝘤𝘩𝘰𝘭𝘵𝘻𝘪𝘪 have higher pyrene and anthracene degradation capacities respectively, highlighting their potential to be used in bio remediation technologies. PAH degradation kinetics of the tested fungal species follow the first-order kinetic model.
