Antimicrobial Potential of Trichaptum Biforme and Bjerkandera Adusta from Pennsylvania, USA

Abstract

The antimicrobial potential of Trichaptum biforme and Bjerkandera adusta extracts were evaluated on some selected bacteria and Candida albicans. Our results showed that aqueous, methanol and ethanol extracts of T. biforme and B. adusta exhibited no antimicrobial activity against Candida albicans. However, some extracts of B. adusta were very effective against three Gram-negative bacteria (Escherichia coli, Salmonella typhimurium and Pseudomonas aeruginosa) and three Gram-positive bacteria (Staphylococcus aureus, Staphylococcus epidermidis and Bacillus cereus). Likewise, extracts of Trichaptum biforme were also effective against all three Gram-positive bacteria and only one Escherichia coli. The effectiveness of these two fungi as antibacterial agents should be well explored with development of optimized methods for mass production of these macrofungi in controlled environments.

Molecular identification and antimicrobial activities of some wild Egyptian mushrooms: Bjerkandera adusta as a promising source of bioactive antimicrobial phenolic compounds

“…In contrast to the current result, Chikwem et al, (2020) observed that B. adusta aqueous, methanol, and ethanol extracts demonstrated no antimicrobial activity against Candida albicans. However, some B. adusta extracts were highly effective against three Gram-negative bacteria (Escherichia coli, Salmonella typhimurium, and Pseudomonas aeruginosa) and three Gram-positive bacteria (Staphylococcus aureus, Staphylococcus epidermidis, and Bacillus cereus) [35]. In agreement with Kumar et al, (2016) [36] Cyclocybe cylindracea displayed a strong antimicrobial activity against Gram-positive Staphylococcus aureus and Gram-negative Klebsiella pneumonia and E. coli that was attributed to its polysaccharide content [36].…”
