The current study involves the effect of zeta potential and magnetic field on the physical properties (electrical conductivity, total dissolved solid, contact angel and surface tension) so as the absorbance by (UV-Visible) on the water in order to compared with them. Also, the use three magnetic devices with different intensities (1000, 2500, 5000) Gauss and zeta rod (ZRS-R) with constant voltage (30±) Kv. The operation system in zeta rod depended on re-cycling the water and sampling during (30, 60, 90) min, but in magnetic treatments were used the water directly after magnetized it. The physical tests showed a clear improvement in the properties of water especially in the surface tension and contact angel about 10% of the original value to the zeta rod treatment and 15% for magnetic treatment in the intensity 5000 Gauss also the results showed the increasing in absorbance, TDS, CON comparing with untreated water. The obvious improvement of the water physical properties approve that magnetic treatment is more effective about7% than zeta rod, especially in the high intensities.

The present study was conducted to investigate the biological degradation of Zearalenone using by Iraqi probiotic 2% (w/v) and yeast filtrate of Saccharomyces boulardii using one of the mammalian system (white mouse ) which had an active influence in removing or reduction of toxic effects of mycotoxin Zearalenone on liver and kidney tissues of males white mice that extracted from fungal isolate Fusarium graminearum produced Zearalenone at concentration (2 mg / kg body weight) . As observed a clear improvement in liver and kidney tissues for group of mice that fed contaminated diet by Fusarium graminearum produced Zearalenone with Iraqi probiotic and yeast filtrate compared with positive control ( group of mice fed contaminated diet by Fusarium graminearum produced Zearalenone ) that caused the histological changes in liver and kidney tissues ,which represented by congestion vascular with necrosis and degeneration in hepatic cells in addition to reduction in glycoprotein granules. While, the histological changes in kidney tissue included congestion vascular and degeneration in distal and proximal tubules. The results of liver enzymes showed significant differences in positive group for three enzymes ALS , ALT and ALP reached ( 15.66, 14.66, 25.66 ) IU/ L respectively, compared with negative control (group of mice did not fed contaminated diet by Fusarium graminearum produced Zearalenone ) which reached for three enzymes ALS , ALT and ALP (15.66,22.00,13.33) IU/ L respectively. However, the results of the interaction between mice fed contaminated diet by Fusarium graminearum produced Zearalenone with Iraqi probiotic and yeast filtrate were shown significant increasing for ALS, ALT, ALP enzymes in addition to urea concentrations in kidney tissue compared with positive control.

The present study has been carried out during the period from January till September 2014. Samples of Rotifera were collected monthly from 5 stations located inside Tigris River at Baghdad city. The maximum recorded density was 40000 Ind/m3 which observed in April at station 5, whereas the minimum density was 450 Ind/m3 at station 1 in January 2014. There were identified 87 species of Rotifera belonged to 29 genera.The results of relative abundance index showed that the species of Rotifera: Keratella quadrata, K. cochlearis, Philodina roseola and Polyarthra ssp. were more abundant in all chosen stations at Tigris River.

Different electrical power were used (1.5, 3, 4.5, 6, 9 and 12 Volts) for removing algal bio mass by using power supply. Algal caused some problems to electrical power stations when cooling it by using river water. The best result appeared at 12, 9, 6 volts which reached to 100% after 30, 45, 75 min respectively. On the other hand the cell wall didn

Silver nanoparticles (Ag-NPs) were extracellular biosynthesized using the mold Fusarium graminaerum that isolated from poultry feed, the fungal isolates were inoculated in a broth medium incubated in a shaker incubator at 25 C0for 8 days, metal nanoparticles were synthesized by treating mycelia (1%w/v) with (1mM, 0.5Mm) of metals oxide solution and incubated in a shaker incubator at 25

The effects of zeta potential on drinking water tanks were studied to find a suitable and cheap method to conserve the water specification biologically by preventing the growth of biofilm inside the inner surfaces of the tanks without any additives. Three plastic tanks were used (1 m3 each); the first one is feed tank, the second is control tank and the third is connected with zeta rod (ZRS-R) that gives constant voltage (30

The present study was to evaluate the histological and biochemical toxic effects of Patulin mycotoxin on liver and kidney tissues of males white mice that extracted from the fungal isolate Penicillium expansum at concentration (3.5 mg / kg body weight) given single and repeated doses of Patulin orally administration and the second aspect of this study using of Iraqi probiotic (local product) as detoxifying agent of Patulin. Mice were divided into four groups five mice for each group, taking into consideration liver and kidney weights. Groups of mice were treated as follows. T1: given the toxin once and sacrificed after two days. T2: given the toxin twice for one week. T3: given the toxin twice a week for two weeks. T4: The last group was treated by Patulin for five days orally with addition Iraqi probiotic (2 %) w/ v in drinking water for fifteen days. Each treated group has its corresponding control which received 1% Dimethyl Sulphoxide (DMSO). The results of the treatment of mice males Patulin of 3.5 mg / kg, in three groups (T1,T2,T3) had caused histological changes in the liver tissue represented by degeneration and necrosis in hepatocytes and had increased with increasing of repeated doses of toxin especially at T3 group that it revealed histological changes represented by congestion of central vein with inflammatory cells in their lumen, lymphocytes infiltration and hemorrhage especially near portal space . The results of liver enzymes showed significant decrease in (Aspartate Aminotransferase) AST, (Alanine Aminotransferase) ALT in treated mice with Patulin (repeated doses) which were involved T2 and T3 group compared with the other groups , while the results of enzymatic activity of (Alkaline phosphatase) ALP showed non-significant decrease in all groups . No obvious significant difference in the concentration of Creatinine in all groups, while urea concentration recorded significant decrease in T2 and T3 groups as compared with T1 and T4 groups. Patulin exhibits Histopathological changes coincided with biochemical changes observed in experiments on male mice and the effect of Patulin depended on time of exposure. The other part of the present study was to investigate the biological degradation of Patulin represented by T4 group using by Iraqi probiotic 2% (w/v) which had an active influence to protect the liver and kidney tissues from the toxic effect of Patulin.
