| Abstract | ||
| Pot experiment was carried out during May 2019 at private farm in el Manyial, Cairo, Egypt. The investigation target was to find out the difference between using plant growth promoting rhizobacteria (B. cereus, Streptomyces chibaensis, B. megaterium, B. polymyxa) either individual or in combination with each other and mineral fertilization on antimicrobial activity and some phytochemical constitutes of Moringa olifera leaves. The highest values of antimicrobial activity recorded for mineral fertilization on treatment followed by mixed biofertilization treatment (GP4) (B. megaterium, B. polymyxa) against seven foodborne pathogens Escherichia coli, Salmonella typhimurium, Staphylococcus aureus, Pseudomonas aeruginosa, Aspergillus niger, Rhizopus stolonifer and Botrytis cinera, as compared with the control treatment. Biofertilization treatment (B. megaterium, B. polymyxa) recorded increasing over control in (GP10) by 160.8% and decreasing of chemical fertilization by 5.41% for polyphenol content, also, the antioxidant content shown increasing over the control (GP10) by 81.1% and decreasing of chemical fertilization (GP9) by 5.6% as well as vitamin C and A were increased with mineral and biofertilizer (GP4) treatments after 55 days. Biofertilization in (GP4) recorded increasing over control group (GP10) by 48.89%, 27.08% and 58% for vitamin A, C and chlorophyll respectively. Ethyl acetate extract was found to be most potent extract than ethanol and water against all tested microorganism. | ||
