Identification and salt tolerance evaluation of endophyte fungi isolates from halophyte plants

  • 48 Accesses


The harsh environments of desert areas lead to natural selection of resistant creatures with obvious characteristics. This experiment looked for salt-tolerant fungi from native halophyte plants. Forty fungi isolated from three halophyte plant families that were collected from desert areas of Yazd Province in Iran, and the most tolerant isolates were selected at concentrations of 1, 2, 3, 3.5 and 4 molar sodium chloride. Five selected superior isolates were assigned to the phylum Ascomycota based on internal transcribed spacers sequences and β-tubulin gene, as well as morphological characteristics of the genus and species. Aspergillus terreus showed superiority in terms of enzymes and antibacterial properties than other isolates. Other isolates were Acremonium, Paecilomyces, Microascus and Monosorascus. Aspergillus terreus also showed antifungal effects against Aspergillus fumigatus, a human pathogen.
