Identification of Endophytic Fungi on the Leaves of Jeruju (Acanthus ilicifolius) which are Potential as Antibacteria

Endophytic fungi are microbes that live in plant tissues and can synthesize the same active biochemical compounds as their hosts. This study aims to determine the type of endophytic fungi of Jeruju leaves (Acanthus ilicifolius) isolate DJS1. This research was conducted in January 2020 and is a type of descriptive qualitative research. The subjects in this study were one type of endophytic fungi isolate that has the potential as an antibacterial. Identification of endophytic fungi of Jeruju leaves (Acanthus ilicifolius) isolated DJS1 which have antibacterial potential by observing macroscopic and microscopic morphological phenotypic characters. Macroscopic observations described the form of colony structure, aerial hyphae forms, and radial lines that appeared on the fungal isolates. Microscopic observations were made to observe the shape of the hyphae and the shape of the conidia. While molecular observations were carried out by amplifying DNA using ITS primers.
