“…Acetone extract showed the maximum antibacterial activity, whereas the most susceptible bacterium recorded was Klebsiella pneumoniae. Bala et al (2011) investigated the antimicrobial effect of 47 different specimens from Australia, and they ascertained that water and ethanol extracts were more effective against S. aureus than E. coli, whereas an inconsiderable number of hexane extracts showed better results for their potential antimicrobial effect against E. coli at higher concentration. In general, a number of macrofungi from the genera Agaricus, Amanita, Boletus, Cantharellus, Fomitopsis, Hohenbuehelia, Lentinus, Ramaria and Strobilomyces demonstrated good inhibition rates.…”

Context: Due to its pleasant aroma and flavor, Amanita caesarea (Scop.) Pers. (Amanitaceae) has been a famous macrofungus since ancient times. This species is also well known in Turkey where people consume it extensively. Objective: Evaluation of the medicinal importance of A. caesarea for human health. Materials and methods: Antioxidant capacity of A. caesarea was studied using the methods of a scavenging effect on 2,2-diphenyl-1-picrylhydrazyl radicals, b-carotene-linoleic acid assay, reducing power and estimation of phenolics. Chloroform, acetone and methanol extracts of A. caesarea were tested for their antimicrobial activity against four Gram-positive bacteria, five Gram-negative bacteria and one yeast by applying a micro dilution method. The fatty acids were estimated via the method of gas chromatography analysis. Results: The scavenging effect of A. caesarea on DPPH radicals was measured as 40.91% at 0.5 mg/mL concentration, and its reducing power was 0.451 mg/mL at 1.2 mg/mL concentration. The phenolics found were catechin (32.5 mg/g), ferulic acid (7 mg/g), p-coumaric acid (6 mg/g) and cinnamic acid (6.2 mg/g). The highest minimum inhibitory concentration observed against the test microorganisms were with the acetone extract (4.8 mg/mL concentration) against Candida albicans. Thirty-seven different fatty acids were determined from A. caesarea, and oleic acid (58%) was the dominant component. Discussion and conclusion: Amanita caesarea had a high-antioxidant and -antimicrobial activity, and it also had important essential fatty acids required for human health. According to the results, this mushroom can be recommended as a major source of natural food.

Context: Terfezia boudieri Chatin (Pezizaceae), Agaricus brunnescens Peck (Agaricaceae) and Lactarius vellereus (Fr.) Fr. (Russulaceae) are well-known species in Turkey, and are used both for food and traditional medicine. Objective: The powdered fruit bodies of T. boudieri, A. brunnescens and L. vellereus were used to evaluate the antimicrobial activities. Materials and methods: Chloroform, acetone and methanol extracts of T. boudieri, A. brunnescens and L. vellereus were tested for their antimicrobial activities against four Gram-positive bacteria, five Gram-negative bacteria and yeast using a micro-dilution method. Results: The strongest minimum inhibitory concentration (MIC) value observed against the test microorganisms was with the chloroform extract of T. boudieri (MIC 2.4 mg/mL) against Streptococcus pyogenes. Maximum antimicrobial effects were observed with the acetone extracts of T. boudieri and L. vellereus (MIC 4.8 mg/mL) against Bacillus subtilis. The strongest antifungal activity was observed with the acetone extracts of T. boudieri (MIC 2.4 mg/mL) and A. brunnescens (MIC 19.5 mg/mL) against Candida albicans. The strongest MIC values for all fungal extracts were observed between 78 and 2.4 mg/mL. Discussion and conclusion: Present results demonstrated that these three mushroom species have excellent antimicrobial and antifungal activities, and thus have great potential as a source for natural health products.

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.
