Background: Fungi have a potential of using both as nutritive and medicinal food stuff. Because of containing several therapeutic agents, they are reported to be used for hundreds of years to treat several diseases caused by bacteria, fungi, viruses and parasites. The aim of this study is to determine the in vitro antimicrobial activity of Xylaria hypoxylon, which were collected from Yomra, Trabzon, Turkey. Materials and Methods: X. hypoxylon samples were air dried and extracted by using ethanol. Results: It is observed that ethanol extracts of X. hypoxylon has antimicrobial activity against several Gram positive and Gram negative microorganisms tested. As a result of the study, an antimicrobial activity of X. hypoxylon found against most of strains used in the study. Conclusion:The results of our study clearly puts forward that X. hypoxylon could have a possible medicinal use.

The aim of this study was to investigate the antimicrobial activity of Lycoperdon lividum against 17 bacterial and 1 fungal strains and analyse the composition of ethanol extracts by GC/MS. The in vitro antimicrobial activity of L. lividum extracts having 15 mg/mL concentration was assessed against a wide range of strains by disk diffusion method. The ethanol extract of L. lividum had antimicrobial activity against several microorganism tested, but it was active especially against S. carnosus. The results obtained herein indicate that L. lividum contains several active metabolites. Article Info

<p class="Abstract">Frankenia hirsuta is widely located in Turkey, but the antimicrobial potential and biochemical composition analysis of it weren’t determined yet. By using the disk diffusion method, the susceptibility of 17 bacteria and 1 fungi were analyzed, which included Bacillus, Candida, Enterobacter, Enterococcus, Esche-richia, Klebsiella, Listeria, Pseudomonas, Salmonella and Staphylococcus genera. 0.8, 1.5 and 3.1 mg of samples were prepared by using absolute ethanol. The bioactive composition of the plant extract was determined by gas chromato-graphy-mass spectroscopy, and National Institute of Standards and Techno-logy library was used for the mass spectra analysis. The results showed that F. hirsuta had antimicrobial activity against all of the studied micro-organisms except E. aerogenes and E. coli. Several active metabolites were identified, but some composition of this sample didn’t match with the library. These results are the first report for the antimicrobial potential and biochemical composition of F. hirsuta.</p><p class="Abstract"><strong>Video Clip of Methodology</strong>:</p><p class="Abstract">3 min 36 sec:   <a href="https://www.youtube.com/v/YeKtYxtaa6c">Full Screen</a>   <a href="https://www.youtube.com/watch?v=YeKtYxtaa6c">Alternate</a></p>

Many plants contain active substances that are known to be effective in both enhancing the wound healing process and lowering the incidence of wound infections. Previous studies have shown that bryophytes produce a variety of secondary metabolites that present pharmaceutical activities including antimicrobial activity against various pathogenic bacteria and fungi. The aim of this study was to investigate the antimicrobial activity of Mnium stellare against 17 bacterial and 1 fungal strains. Our present study has shown that the ethanol extract of M. stellare has antimicrobial activity against several Gram positive and negative microorganism tested, but its antimicrobial activity is notable especially against B. subtilis, S. typhimirium, S. aureus, S. carnosus, and S. epidermidis. These results are the very first report of the antimicrobial activity of M. stellare.
