The aim of the current research is to study the effect of adding green tea to the edible film prepared from the whey protein isolate on the effectiveness of microorganisms and evaluating the of antimicrobial effectiveness of these films on Iraqi soft cheese packaging during the nine days of storage as an alternative to commercial packaging. At the beginning of the study, the minimum inhibitory concentration was measured by calculate the diameter of the zone of inhibition on growth of the bacteria and it's included the group of Gram negative bacteria (Escherichia coli, Salmonella spp, Pseudomonas Aeruginosa) and the group of Gram positive bacteria (Staphylococcus Aureus, Bacillus spp) and a yeast (Candida Albican). Where the diameter of the halos formed (11, 20, 10, 7, 14, 16) respectively. The changes in the microbial numbers were also observed during the storage period. In this study, two treatments of Iraqi soft cheese were used. The first treatment of the cheese was uncoated as a control treatment (T1 treatment) & the second treatment of the cheese (T2 treatment) was coated with the film of the whey protein supported by the green tea extract.The results of the experiments were conducted to estimate the numbers of microorganisms indicate that there are significant differences in the last days of storage Between the two treatments and at a significant level of 0.05 in both the total count bacteria and total coliform bacteria and staphylococcus number, The numbers of bacteria have decreased about 1-2 Logarithmic CFU/gm, and approximately 2-3 Logarithmic CFU/gm in relation to the number of staphylococcus aureus. It was also found that there were significant differences at a significant level of 0.05 Between the T2 treatment of Iraqi soft cheese models compared to the T2 treatment for the number of sychrotrophic bacteria and the reduction in numbers was approximately 2-3 Logarithmic CFU/gm, and the number of molds and yeast decreased by 0.5-1.5 Logarithmic CFU/gm, The treatment of cheese packaging has increased the age of cheese the results of the sensory evaluation of T1 (non-coated cheese) and T2 were improved that the coated cheese was obtained a higher grades during the storage period.
The increasing efficiency of the telecommunications network in the city contributes to the increase in spatial interaction between activities (to influence and mutual influence) This study is based on the idea that the upgrading of telephone services provided to citizens are done exclusively through the growth and development of all levels of the service using advanced technologies to know the problems and appropriate solutions in short time and less cost. Thus, crystallized the objectives of the study which was built for the importance of GIS in the planning of services in general, and infrastructure services, in particular, including telephone services, which is represent a point of contact between individuals on the one hand a

The compound (1) was reacted with different aldehydes and ketones to give Schiff bases derivatives 2(a-j). The synthesized Schiff bases were cyclized by chloroacetyl chloride in the presence of triethylamine to form beta-lactam derivatives 3(a-j). The compounds were characterized by deremination melting point, FT-IR and 1H NMR. The beta-lactam derivatives were screened in vitro antibacterial against some bacterial species

Show MoreAn antibacterial and antifungal piperonal-derived compound and its Rh(III), Pd(II), Pt(IV), and Cd(II) metal complexes were synthesized and characterized by spectroscopic methods, conductivity, metal analyses and magnetic moment measurements. The nature of the complexes formed in ethanolic solution was studied following the molar ratio method. From the spectral studies, octahedral geometry was suggested for rhodium (III) and platinum (IV) complexes, while a square planer structure was suggested for palladium (II) complex and a tetrahedral geometry for cadmium (II) complex. Structural geometries of these compounds were also suggested in gas phase by using hyperchem-8 program for the molecular mechanics and semi-empirical calculations.

A new series of schiff base and aminothiadiazole derivatives of N- substituted phthalimide (I-VI) were synthesized. In this work, the intermediate 4-(1,3-dioxoisoindolin-2-yl)benzaldehyde compound (I), was formed by reaction of 4-amino benzaldehyde with phthalic anhydride in glacial acetic acid(GAA). A series of Schiff bases (IV-VI) was prepared by the reaction of benzidine with compound (I) in ethanol and presence of GAA as a catalyst to form compound (IV) which react with compound (I) and p-nitro benzyldehyde to give compound (V) and (VI) respectively.
