Abstract

• Glabba is a genus of plants in the ginger family and contains about 100 species. In this research work, the plant samples (leaves and rhizomes) of Globba arracanensis Kurz. were collected from Nat-Taung-Pyin Hill, Pauktaw Township in Rakhine State in September, 2023. G. arracanensis Kurz. is only found in Rakhine State and it is now known not to be extinct. The morphological and microscopical characters of all fungal strains were carried out at Microbiology Laboratory, Department of Botany, Dagon University. The colony appearances of isolated fungal strains were irregular, circular and rhizoid. The colony margins of isolated strains were entire, filamentous, undulate and lobate. The elevations of isolated strains were raised, flat and pulvinate. The surface and reverse colors of isolated fungal strains were white, whitish pale yellow, whitish orange, light orange, whitish green, whitish yellow. whitish grey. The colony characters and microscopic characters of isolated fungi are very closed to Penicillium, Rhizopus, Rhizoctonia, Cladosporium and Aspergillus species. Strains Eaindra-5, Eaindra-6, Eaindra-9, Eaindra-12 and Eaindra-13 were identified as Penicillium species, strains Eaindra-8 and Eaindra-11 as Aspergillus species, strain Eaindra-3 as Cladosporium species, strain Eaindra-10 as Rhizopus species and strains Eaindra-2 and Eaindra-14 as Rhizoctonia species. These isolated strains possessed good antimicrobial activity on some pathogenic organisms so that this activity will be presented in the next paper.
