Antimicrobial activity of aqueous extract of Laetiporus sulphureus (Bull.: Fr.) Murill

Wood-rotting basidiomycete, Laetiporus sulphureus (Bull.: Fr.) Murill., also known as chicken of the woods, is known for its nutritional value. In this study, aqueous extract obtained from L. sulphureus was investigated for its antimicrobial properties using microdilution in vitro assay. Plant, animal and human pathogens, as well as food spoilage agents, were tested. Aqueous extract obtained from L. sulphureus showed strong activity against the tested microorganisms in a dose dependent manner. Considering that there is a constant emerging of pathogen resistance to the known synthetic agents, there is an undeniable need for new therapeutical drugs and preservatives in food industry. Thus, these results that indicate activity of natural products may be of practical use.
