In vitro antimicrobial screening of cerena unicolor (Bull.) murrill (Polyporaceae fr. ex Corda)

Abstract

The aim of this study is to determine the antimicrobial activity of Cerena unicolor ethanolic extract against 19 bacterial and 1 fungal strains. C. unicolor samples which were collected from Yomra, Trabzon, TURKEY were extracted with ethanol. Extracts were investigated for in vitro antimicrobial activity against a wide range of strains including Bacillus cereus DSMZ 31, Bacillus subtilis ATCC 6633, Candida albicans ATCC 10231, Enterobacter aerogenes ATCC13048, Enterococcus durons, Enterococcus faecalis ATCC 29212, Enterococcus faecium, Escherichia coli ATCC 25922, Escherichia coli CFAI, Klebsiella pneumonia, Listeria monocytogenes ATCC 7644, Pseudomonas aeruginosa ATCC 27853, Salmonella enteritidis ATCC 13075, Salmonella infantis, Salmonella kentucky, Salmonella typhimurium SL 1344, Staphylococcus aureus ATCC 25923, Staphylococcus carnosus MC1.B, Staphylococcus epidermidis DSMZ 20044 and Streptococcus agalactiae DSMZ 6784 by using the disc diffusion method. It is observed that ethanolic extract of C. unicolor has antimicrobial activity against several gram positive microorganims tested. As a result of the study, it could be concluded that ethanolic extract of C. unicolor is active against several microorganisms but its antimicrobial activity is notable especially against B. cereus DSMZ 31, S. carnosus MC1.B and S. epidermidis DSMZ 20044. © by PSP.
