Pleurotus spp are edible mushrooms that have also high nutritional and medicinal value. The aim of the present study was to evaluate the antimicrobial activities of Pleurotus pulmonarius intra- and extracellular extracts, obtained in submerged cultures using different carbon sources (glucose, cassava starch and cassava bagasse) and cultivation times of up to 8 days. The antimicrobial activities were characterized by evaluating the zone of inhibition, the minimal inhibitory concentration and the bactericidal concentration (MIC and MBC, respectively). The results showed that highest antimicrobial activities were found in 6 day mycelial extracts obtained in cultures using glucose and starch as carbon source. These extracts presented considerable antimicrobial activity against Escherichia coli, Salmonella enterica, Staphylococcus aureus, Bacillus subtilis and Bacillus cereus. The same extracts were also able to inhibit growth of Candida albicans. These results shows that the mycelial extracts of P. pulmonarius are promising natural source of antimicrobial agents.
