Developing secondary metabolites in plants with antifungal characteristics, offer alternative medications for reasonably priced and safe treatments. In the present study, methanolic, ethanolic, hexane and ethyl acetate leaves extracts of fifteen Apiaceae family plants were taken on the premise of their ethno botanical uses. The antifungal activity was assessed against significant fungal strain;Aspergillus fumigates by measuring minimum inhibitory concentration (MIC) and Zone of inhibition compared with standard drug fluconazole. Ethanol and methanol extracts of the plants were more effective than the hexane and ethyl acetate extracts against A. fumigates. Extracts of Cuminum cyminum, Pastinca sativa, Carum carvi, Dacus carota, Centella asiatica, Anthriscus cerefolium, Trachyspermum ammi, Pimpenella anisum and Apium graveolens showed relatively low inhibition effects between 3.5 to 8.5 mm. The MIC value of extracts was determined ranging between 0.8 to 0.43 μg/ml. The extract of Petroselinum crispum, Foeniculum vulgare, Ferula assaefoetida, Bunium persicum, Anethum graveolens and Coriander sativum could be considered as potential source of antifungal compounds for treating diseases in humans. Conclude remarks that these six extracts show astonishing fungicidal properties that can be used to discover drugs of very high potential.展开更多

The samples were separately treated with Aspergillus niger and Pseudomonas aeruginosa. The bioremediation kinetic efficiency for these systems was studied. At the end of the bioremediation periods, the oil and grease content of the samples decreased from 47.0 mg/L in the untreated sample to 7.0 mg/L after 20 days when inoculated with bacteria while the sample inoculated with fungi decreased to 10.0 mg/L. Post analysis when inoculated with bacteria showed a fall in the value of the biological oxygen demand (BOD) from 73.84 mg/L to 33.28 mg/L after 20 days, while, the fungi inoculated sample showed a reduction from 73.84 mg/L to 38.48 mg/L. The biodegradation process with the bacteria was consistent with the pseudo-first-order model with a rate constant of 0.0891 day<sup>-1</sup>, while the biodegradation process with the fungi was consistent with the first order reaction model with a rate constant of 0.422 day<sup>-1</sup>. The degree of degradation after the 20<sup>th</sup> day of inoculation with Pseudomonas aeruginosa was 85.11%, while with Aspergillus niger was 78.72%. Thus, the results obtained showed that, Pseudomonas aeruginosa performed better than Aspergillus niger. The bioremediation data with fungi fitted the first-order model, while that of the bacteria fitted the pseudo-first-order model. Therefore, the data obtained in this study could be applied in the design of a bioremediation system for potential application to remediation of crude oil polluted water.展开更多
