ABSTRACT
CONTEXT Amanita ovoidea (Bull.) Link (Amanitaceae) is a well-known species due to its pleasant aroma and flavor since ancient times in the worldwide. This species is also known in Turkey and people consume it extensively.

OBJECTIVE:

To evaluate medicinal importance of A. ovoidea for human health, to explain the effect of mushroom extracts on bacterial DNA, and to find preventive role on bacterial disease. MATERIALS AND

METHODS:

Chloroform, acetone, and methanol extracts of A. ovoidea were tested for the antimicrobial activities against four Gram-positive bacteria, five Gram-negative bacteria, and yeast using a micro-dilution method. In addition, DNA binding, DNA cleavage activity, and restriction enzyme digestion of the methanol extract of A. ovoidea were examined at different concentrations (40.000-78.125 µg/mL).

RESULTS:

The highest minimum inhibitory concentration (MIC) value observed against the test micro-organisms was with the chloroform extract (MIC 19.5 µg/mL concentration) against Candida albicans. Other highest antimicrobial effects observed against the test micro-organisms were with the methanol extracts against Bacillus subtilis, Staphylococcus aureus, Listeria monocytogenes, Streptococcus pyogenes, Candida albicans, Klebsiella pneumoniae, Proteus vulgaris, and Salmonella enteritidis (MICs, 78 µg/mL concentrations). All concentrations reduced the mobility of plasmid DNA. BamHI and HindIII targeted specially to supercoils and cut them. Amanita ovoidea extract prevented cutting with HindIII by binding especially to the AA region in open circular DNA. DISCUSSION AND

CONCLUSION:

Present results demonstrated that A. ovoidea has excellent antimicrobial and antifungal activities by its DNA interaction activity on pBR322.
