Antimicrobial activity of ginger (Zingiber officinale) extracts against food-borne pathogenic bacteria
Ginger (Zingiber officinale) has long been used as naturopathy due to their potential antimicrobial activity against different microbial pathogens. Moreover, in many countries like Bangladesh, ginger is used in different boiled food preparations. This study was conducted to determine the antimicrobial activity of soybean oil extract of dried ginger powder, using agar diffusion assay, against 24 isolates (4 of 6 different types) of food borne pathogens including Escherichia coli, Pseudomonas aruginosa, Staphylococcus aureus, Vibrio cholerae, Klebsiella spp. and Salmonella spp. The present study showed the potent antimicrobial activity of the ginger extract against the all tested bacterial pathogens. Soybean oil extract of ginger showed highest zone of inhibition (11.67±1.53mm) against Salmonella spp. and lowest zone of inhibition (8.0±1.73mm) against Escherichia coli. Ginger extract also showed lower zone of inhibition (8.67±2.52mm) against Staphylococcus aureus compared to the Gram-negative bacteria. Soybean oil extract of ginger at boiling temperature has potential antimicrobial activity and could be used in food preparation to get the synergistic effect of soybean and ginger.
P.S Anti-dht approach would be at broader level of the PB but wont be an issue of the SBGlands are not inflamed and thus turning into harbours for germs. Possibly for Salmonella ?
