Bikaverin is a reddish pigment produced by different fungi species (Mycogone jaapii, Verticillium agaricinum, Beauveria bassiana, Paecilomyces fumosoroseus, Polyporus sulphureus), mainly of the Fusarium genus. Due to its pigment feature, bikaverin can be used as a dye in various fields in the industry. However, it is extremely important to study the mutagenic/genotoxic effects, cytotoxic effects and antimicrobial properties of bikaverin for application of industrial areas. In the study, the mutagenic, cytotoxic and antimicrobial effects of bikaverin were investigated. The mutagenic effect of bikaverin was studied with the Ames test. Salmonella typhimurium TA97a, TA98, TA100, TA102 and TA1535 strains were used in the test. Five different doses of bikaverin (0.075, 0.1, 0.2, 0.3 and 0.5 μg/plate) were tested against strains. It was determined that there was no mutagenic effect of bikaverin. The cytotoxicity of bikaverin was evaluated by MTT test on L929 fibroblast cell line. Bikaverin demonstrated no cytotoxic effect on L929 fibroblast cell line, according to cell viability calculations that showed >73% for all concentrations (1, 0.5, 0.4, 0.3, 0.2, 0.1, 0.075, 0.05, 0.025, 0.01, 0.005 and 0.001 μg/mL) examined. Bikaverin's IC50 value was determined to be 1.79±0.51 g/mL. The antimicrobial activity of the bikaverin was evaluated by using the microdilution method. Bikaverin was found to have antimicrobial effects on Methicillin resistant Staphylococcus aureus, Vancomycin resistant Enterococcus faecalis, Staphylococcus aureus, Escherichia coli, Pseudomonas aeruginosa, Klebsiella pneumoniae, Candida albicans and Candida krusei, as MIC values ranged from 1.25 -5 µg/ mL.
