Aims: This study investigated the antifungal activities of essential oils (EOs) extracted from anise ( Pimpinella anisum ) and fennel ( Foeniculum vulgare ) against indoor opportunistic fungi ( Penicillium frequentans , Aspergillus flavus , Aspergillus niger and Chaetomium globosum ) isolated from an apartment wall surfaces. The antioxidant activity of extracted EOs was examined. Methodology and results: The components of EOs were identified and quantified using gas chromatography (GC-MS). Antifungal activity, minimum inhibitory concentration (MIC) and killing potential assays of EOs were performed. EOs extracted from anise and fennel showed considerable antifungal activities against the four indoor opportunistic fungi. EO from fennel showed high antifungal activity against A. niger and C. globosum , while EO from anise showed high antifungal activity against P. frequentans and A. flavus . EOs from anise and fennel showed the same MIC values (5-8 mg/mL). EOs from anise and fennel showed high killing potential after 72 h against the indoor opportunistic fungi. The highest killing potential was against P. frequentans and the lowest killing potential was against C. globosum . Moreover, EOs from anise and fennel showed high antioxidant activities with scavenging activity after 90 min of 89.39% and 90.2%, respectively. Conclusion, significance and impact of study: EOs extracted from anise and fennel could be used as natural antifungal agents against indoor opportunistic fungi.

Aims: This study was aimed at detecting the presence and quantity of fumonisins in maize sold in different markets in southern Nigeria, thereby igniting our awareness of the dangers in their patronage. Methodology and results: The incidence of potential mycotoxin producers was determined on samples (n=60) of maize collected randomly from three different markets, each in six states in Southern Nigeria. The fungi were cultured using the direct plating method on potato dextrose agar and dichloran rose bengal chloramphenicol agar. Pure cultures (n=90) obtained were tentatively identified using cultural and morphological characteristics. Molecular identification was carried out by obtaining fungal DNA and the amplified DNA. Sequences of DNA were blasted against the nucleotide database of NCBI to identity the isolates. The fungal isolates identified belong to 10 genera, with Aspergillus and Fusarium had the highest number of occurrences, followed by Trichoderma. The highest amount of fumonisin (13.45 ppm) was produced by Fusarium verticilloides strain KN11 and the least amount of fumonisin (0.01 ppm) was produced by F. venenatum strain MNF5. Maize samples were found to contain varying degrees of fumonisin, with isolates from Cross River State having the highest percentage. Conclusion, significance and impact of study: The contamination of food by fumonisin is a severe threat to disease outbreaks worldwide. Results highlight a food safety risk that the government need to monitor and educate consumers. More emphasis should be given to the application of nanotechnology and genetic engineering in developing resistant varieties of crops to ensure the safety and quality of food for future generations.
