Isolation and Classification of Green Alga Stigeoclonium attenuatum and Evaluation of its Ability to Prepare Zinc Oxide Nanoflakes for Methylene Blue Photodegradation by Sunlight
...Show More Authors

           Algae have been used in different applications in various fields such as the pharmaceutical industry, environmental treatments, and biotechnology. Studies show that the preparation of nanoparticles by a green synthesis method is a promising solution to many medical and environmental issues. In the current study, the green alga Stigeoclonium attenuatum (Hazen) F.S. Collins 1909 was isolated and identified from the Al-Hillah River (Governorate of Babylon) in the middle of Iraq. The green synthesis by the aqueous extract of algae was used to prepare the nanoflakes of ZnO. Nanoflakes of ZnO are characterized by X-Ray diffraction (XRD) and scanning electron microscope (SEM) with flakes shape and dimensions ranging between 200-500 nm and thickness between 20-23 nm. And this study comprises a test of ZnO nanoflakes efficiency as a photocatalyst factor, thus experiments set of an aqueous solution of methylene blue with ZnO nanoflakes and exposed to sunlight have been conducted. The absorbance of methylene blue at 660 nm reduces over time and almost vanishes between 60-120 minutes. Consequently, it is obvious that in the presence of sunlight, pristine ZnO nanoflakes are photocatalytically active with a degradation efficiency of 97%. Furthermore, the antibacterial activity of ZnO nanoflakes that were prepared by aqueous extract of algae was evaluated against some resistant strains of bacteria Escherichia coli, Klebsiella pneumoniae, Staphylococcus aureus, and Streptococcus sp. and the antibacterial activity of NPs rises as concentration increases 50, 100, and 150 μg/ml.

Isolation and antimicrobial resistance of Staphylococcus spp., enteric bacteria and Pseudomonas spp. associated with respiratory tract infections of sheep
...Show More Authors

Sheep are considered as an important part of livestock in the worldwide, particularly in Iraq, as they provide meat, milk, leather, wool, and manure. The present study aim is isolation and identification of staphylococci, enteric bacteria and Pseudomonas spp. Totally, 115 samples were collected from sheep (100 samples were collected from the nasal cavity of local sheep suffering from respiratory infections, and 15 samples were collected from apparently healthy local sheep). All the samples were collected from seven flocks located in Abu Ghraib and Al-Radwaniyah, Baghdad governorate, Iraq. The samples were taken during the period from October 2020 to February 2021. Staphylococcus spp., Pseudomonas spp., and enteric bacteria were detected fi

Isolation and Diagnosis of Aerobic Bacteria from Patients with Respiratory Tract Infection and Partial Characterization of Their Plasmid Profile
...Show More Authors

   In this study, the bacteria from sputum specimens of patients with respiratory tract infections were isolated in   IbnSina Teaching Hospital, Mosul city, Iraq.  The bacteria  were subjected to phenotypic and biochemical tests necessary for identification. Twenty five isolates of six different bacterial species were obtained, they are : Staphylococcus aureus, Streptococcus pneumonia, Moraxella cattarhalis, Escherichia coli, Klebsiella pnuemoniae and Pseudomona saeruginosa with ratios (64%, 12%, 8%, 8%, 4% and 4% ) respectively. The sensitivity and resistance of these isolates to 12 antibiotic were studied, where the Gentamycin appear to be more effective on most of the isolates while all the isolates showe

...Show More Authors

Capparis spinosa is one of the oldest genera grown in Iraqi land with worldwide traditional medicinal uses beside the culinary uses. These uses were own to the presence of many phytochemical including flavonoids, polyphenols. Among the reported polyphenolic acids are caffeic, chlorogenic and ferulic acids with well-known powerful antioxidant properties.

Novel Sorbent of Sand Coated with Humic Acid-Iron Oxide Nanoparticles for Elimination of Copper and Cadmium Ions from Contaminated Water
...Show More Authors

Nanoparticles of humic acid and iron oxide were impregnated on the inert sand to produce sorbent for treating groundwater contained of cadmium and copper ions by technology of permeable reactive barrier (PRB). Sewage sludge was the source of the humic acid to prepare the coated sand by humic acid—iron oxide (CSHAIO) sorbent; so, this work is consistent with sustainable development. For 10 mg/L metal concentration, batch tests at speed of 200 rpm signified that the removal efficiencies are greater than 90% at sorbent dosage 0.25 g/ 50 mL, pH 6 and contact time 1 h. The kinetic data was well described by the Pseudo first-order model indicating that physicosorption is the predominant mechanism. The maximum adsorption capacities (qmax) were c
