Abstract

nhibitory action of the aqueous (WE), acetone (AE), methyl (ME), and volatile oil (OE) Of Trigonella Foenum_Graecum seeds against some pathogenic bacteria was evaluated. Different concentration (20, 50, 80) mgml of the extract were used against gram-negative (Escherichia coli and Pseudomonas spp.) and gram positive (Bacillus subtilis and Staphylococcus aureus) bacteria. The result obtained from this study varied according to the type of extract, microorganism and the concentration used. Volatile oil extract had shown efficiency inhibiting both gram negative and positive bacteria in all concentration. So acetone, methyl and aqueous extract had shown efficiency inhibiting both gram negative and positive bacteria in 80 mgml concentration. While the last extracts had no efficiency inhibiting against study bacteria in 20mgml concentration, and they no effected at the negative bacteria in 50mgml concentrations, so the aqueous extract had no effect against positive bacteria in the same last concentration. The volatile oil extract seed was considered to be the most efficient against all tested bacteria comparing with other. Thus it was applied on preserving cooled minced beef by using different concentrations (0, 5, 15, 25, 50, 100) mgkg of meat. As a result showed low in the number of total bacteria count, total coli form count and total mold and yeast count c by using highest concentration of extracts during the storage at(2±7)oc comparing with control sample.
