ABSTRACT
Twelve plant extracts extracted in Vidya herbs Pvt. Ltd., were studied for their antimicrobial potency against food borne pathogens viz. Emblica officinalis, Moringa oleifera, Terminalia chebula, Coffea arabica, Withania somnifera, Cinnamomum verum, Gymnema sylvestre, Morinda citrifolia, Curcuma longa, Theobroma cacoa, Mucuna pruriens and Punica granatum against food borne pathogens. E. officinalis, Morinda citrifolia, W. somnifera, M. oleifera and P. granatum have proved the best plant extracts by inhibiting all the bacterial growth evidenced by wider and clear zones of inhibition. M. oleifera inhibited S.aureus, B. licheniformis, B. megaterium and L. acidophilus at 46.66, 33.33 and 19.99mg/ml with zones of 17, 18, 17 and 17 mm, respectively. B. licheniformis was sensitive when treated with W. somnifera at 40, 20, 10 and 5 mg/100μl concentrations and inhibition zone was 24.45, 23.5, 21.7 and 19.25mm, against S. aureus, B. licheniformis, B. megaterium and L. acidophilus, respectively. E. officinalis inhibited S. aureus even at less concentration i.e. 24mg/60μl with wider zone 33mm comparable to standard. M. citrifolia was found to inhibit all the organisms with wide and clear zones. A sensitive bacterium was S. aureus with wider zone of 30.5, 20.25, 16.25 and 12 mm at 40, 20, 10 and 5 mg/100μl, respectively. SEM was performed in order to visualize the actual damage in treated fungi viz. Aspergillus niger and Aspergillus fumigatus. It is clear from the microscopic observation that the spores were totally emaciated with irregular size and shape when treated with extracts of the study. Thus, most of the plant extracts have shown the potential inhibitory activity against food pathogenic bacteria and could become promising natural antimicrobial agents with potential applications in neutraceutical/pharmaceutical industry for controlling the food borne pathogenic bacteria.
