This study investigated the Phytochemical and antibacterial effects of wild Ganoderma species on some foodborne bacteria. Standard tests were used to detect the quality and quantity of phytochemicals on the fruiting body of different wild Ganoderma spp as well as the Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal concentration (MBC) of the Ganoderma spp. against the test microorganisms. The result showed that saponin, alkaloids, anthroquinones, steroids, flavonoids, terpenoids, phytates, hydrogen cyanide, oxalates, and glycosides were present in the four Ganoderma samples at different concentrations. Oxalates and terpenoids were absent in Ganoderma resinaceum, Ganoderma applanarum, and Ganoderma lucidum. Cyanide recorded the highest concentration in Ganoderma lucidum while steroids showed least concentration level in Ganoderma resinaceum. The ethanolic extracts of Ganoderma spp. fruiting bodies showed antibacterial effect against Salmonella spp., Escherichiacoli, Staphylococcus aureus and Streptococcus spp. However, highest inhibitory concentration is observed against Streptococcus spp.(1.34 mg/ml) while Salmonella spp. has the lowest inhibitory concentration (0.318 mg/ml). The highest antibacterial activity was seen in the ethanolic extract of Ganoderma applanarum, against Escherichia coli (19.50 mg/mL) higher than the reference antibiotic streptomycin (MIC= 15.62 µg/mL). The MBC value for the four Ganoderma spp used showed almost uniform bactericidal (250 mg/ml) concentrations. G. lucidum ethanolic extract showed antibacterial activity against Streptococcus spp. of 16.10 mg/ml, at …
