Fifty-one extracts from mycelia and growth broth were prepared from higher Basidiomycetes mushrooms, from which eight extracts (from Ganoderma resinaceum, Laetiporus sulphureus, Dictyopanus pusillus, and Bjerkandera adusta) showed antimicrobial activity against Xanthomonas vesicatoria, Aspergillus oryzae, Penicillium expansum, Botrytis cinerea, and Rhizopus stolonifer as assayed in the qualitative test. The minimum inhibitory concentration (MIC) for those fungal extracts was determined and the results showed that L. sulphureus deserved further study, with low MIC values against X. vesicatoria. The antimicrobial activity of L. sulphureus culture broth extracts grown under different culture conditions was evaluated against X. vesicatoria. From the results of these assays, larger-scale cultures for the production of the compound(s) with antimicrobial activity should be performed using malt extract broth, at pH 5, at 20°C and static culture conditions.
