چکیده

phoenix dactylifera a collection of flowers in each inflorescence branches grown on a diet of dates in the series are drawn oval wooden sheath. in this study, the antimicrobial properties against pathogenic bacteria phoenix dactylifera well dilution method (micro dilution) and disc diffusion and mold spoilage due to extract the disk diffusion method was studied. tarvnh extract the bacteria bacillus cereus, salmonella, or general shrshya, staphylococcus aureus, and the fungus trichoderma, aspergillus niger and aspergillus oryza produces inhibitory and germicidal effect that the greatest effect on salmonella enterica bacteria with minimum inhibitory concentrations (mic) against 5,000 minimum concentration of germicidal (mbc) against 5000, and the average diameter of the inhibition zone, mm) (5/13 that passes between the fungus and the greatest effect on trichoderma mean percentage inhibition 25/83 percent, respectively. results showed that the extract tarvnh bacterial growth can be productive and disease-causing food to prevent spoilage., so you can use it as a mix preservatives and flavors of natural food product can offer
