Biological activity of Macromycetes isolated from Chilean Subantarctic ecosystems

Abstract

Twenty six compounds were identified by GC-MS analysis from culture broth of six Macromycetes growing in subantarctic forests in southern Chile: Mycena hialinotricha, Collybia butyracea, Inocybe geophylla, Entoloma nubigenum, Stropharia semiglobata and Psathyrella sp. Antifungal and antibacterial activity were evaluated through agar diffusion test. This assay showed bioactivity against Penicillium notatum, Fusarium oxysporum, Rhyzoctonia solani, Ceratocistys pilifera, Bacillus subtilis, Pseudomonas aeruginosa, Escherichia coli, Escherichia faecalis and Staphilococcus aureus.
