Antimicrobial and phytochemical potentials of arbuscular mycorrhizal fungi in Nigeria

Abstract

Studies were carried out on the antimicrobial effect of aqueous, ethanolic, methanolic and hexane extracts of mycorrhizal fungi; Glomus clarum and Gigaspora gigantea against selected pathogenic microorganisms using well-plate and disc-diffusion methods. The highest antibacterial inhibitory activities (10 mm) were recorded for methanolic extract of Glomus clarum against Proteus vulgaris and Klebsiella pneumoniae. Hexane extract of G. clarum produced the highest antifungal activities (20 mm) against Aspergillus flavus. Generally, the antimicrobial activity of Glomus clarum extracts was significantly higher than that of Gigaspora gigantea. The minimum inhibitory concentration (MIC) was 0.1-0.4 mL for the extracts. Shigella sonnei was resistant to all extracts. The phytochemical screening carried out for the extracts showed that all extracts contained alkaloids and anthraquinone.

Antibacterial Potential of Arbuscular Mycorrhizal Fungi - A Rewiew

“…If AM fungi have primary access to photosynthates then the higher carbon demand may inhibit pathogen growth (Nath and Meena, 2018) The different aqueous, ethanolic, methanolic and hexane extract of the mycorrhizal fungi used for the investigation of antibacterial and antifungal properties against the tested organisms using both well-plate method and disc diffusion method. The result confirms that mycorrhizal fungi show antimicrobial activities and capable of attracting industrial investment in sustainable agriculture (Fapohunda et al, 2013).…”
