STUDY THE INHIBITION ACTIVITY OF PURIFIED BACTERIOCIN FROM LOCAL ISOLATION Lactococcuslactis ssp. lactisagainst SOME PATHOGENIC BACTERIAL SPECIES ISOLATED FROM CLINICAL SAMPLES: دراسة الفعالية التثبيطية للبكتريوسين المنقى من العزلة المحلية Lactococcuslactis ssp. Lactis تجاه بعض البكتريا الممرضة المعزولة من عينات سريرية

This study aimed to study the inhibition activity of purified bacteriocin produced from the local isolation Lactococcuslactis ssp. lactis against pathogenic bacteria species isolated from clinical samples in some hospitals Baghdad city. Screening of L. lactis ssp. Lactis and isolated from the intestines fish and raw milk was performed in well diffusion method. The results showed that L. lactis ssp. lactis (Lc4) was the most efficient isolate in producing the bacteriocin as well observed inhibitory activity the increased that companied with the concentration, the concentration of the twice filtrate was better in obtaining higher inhibition diameters compared to the one-fold concentration. The concentrated bacteriocin was purified using the gel filtration column and Sephacryl S-200. The results showed the high inhibitory activity of the purified bacteriocin after the purification against the positive and negative bacteria of the Gram stain under study compared to the one-fold concentration and two-fold before purification , The diameters of the inhibition zones after gel-filtering of the purified bacteriocin reached S. aureus, S. epidermidis, P. aeruginosa, E. coli, E. clocae and S. marcescens (23, 25, 26, 20, 22 and 28) Mm respectively. The carbohydrate content of purified bacteriocin from L. lactis ssp. lactis (Lc4) isolate was 6.02% with a molecular weight of 6310 Dalton. The results showed that purified bacteriocin retained its inhibitory activity at pH 2-10 and showed the highest inhibition at pH 4-6 and lost at pH 12. The purified bacteriocin was characterized by thermal stability. It retained its effectiveness when exposed to 40, 60, 80, 100°C for 30, 15, 5 minutes and 120°C for 15.5 minutes and lost 50% of its effectiveness when exposed to 120°C for 30 minutes. Results The purified bacteriocin was effectively retained when treated with enzyme pepsin and trypsin of 37°C for one hour and at pH 7.

Synthesis, Characterization, Biological Activity and Thermal Study of New Complexes [Ni II, Hg II and La III] from Mixed Ligands (Curcumin and Azo compounds type N2O2)
...Show More Authors

The compound [L] was produced in the current study through the reaction of 4-aminoacetophenon with 4-methoxyaniline in the cold, concentrated HCl with 10% NaNO2. Curcumin, several transition metal complexes (Ni (II), La (III), and Hg (II)), and compound [L] were combined in EtOH to create new complexes. UV-vis spectroscopy, FTIR, AA, TGA-DSC, conductivity, chloride content, and elemental analysis (CHNS) were used to describe the structure of produced complexes. Biological activities against fungi, S. aureus (G+), Pseudomonas (G-), E. coli (G-), and Proteus (G-) were demonstrated using complexes. Depending on the outcomes of the aforementioned methods, octahedral formulas were given as the geometrical structures for each created comp

Drawing inspiration from organic natural forms in stereoscopic sculptures (A survey according to Evo-devo science)
...Show More Authors

By reading the book (Endless Forms Most Beautiful: The New Science of Evo Devo) by Sean B. Carroll, new horizons opened up about the nature of the formation of the living organism. Although he presented the idea that the artist was influenced by the material assets of nature in his holographic art formations, the new science of Evo-Devo (Evolutionary Developmental Science) provided models worth standing on when comparing the similarity of the formation of living organisms on the one hand, and the formation of works of art with holographic organic bodies on the other. But the excitement lies in the fact that the formation of living natural organisms is often driven by subtle intelligent mechanisms that are different from the mechanisms us
