Abstract
The objective of this study was to analyze mycelial growth under different culture conditions and antimicrobial activity of Pleurotus ostreatus (Jacq.: Fr.) Kumm. (DPUA 1533) and P. ostreatus (Jacq.: Fr.) Kumm. cv. Florida (DPUA 1534) against fungi and bacteria of medical importance. The growth of Pleurotus species was evalu- ated in natural and complex media, with and without light, at 25°C and 28°C for 8, 15, and 30 days. Candida albicans (DPUA 1336), Cryptococcus laurentii (DPUA 1501), Aspergillus flavus (DPUA 1836), Escherichia coli (DAUPE 224), and Mycobacterium smegmatis (ATCC 607) were used to test antibiosis. Under all growth conditions in vitro, Pleurotus species evidenced growth and high density of mycelia on potato dextrose agar and Sabouraud agar with yeast extract; mycelial growth but lesser mycelial density was observed on rice bran extract agar. Organic mycelial extracts of Pleurotus species exhibited potential antibacterial and antifungal activity, and were selective for the tested microorganisms.
