Selenium is an essential trace mineral that prevents the formation of pro oxidative free radicals. The role the selenium plays in the protection of hemoglobin against peroxidation is very well documented and researched. In order to perform this study, a number of 20 3-weeks-old broiler chickens of the Cobb breed were analyzed. The individuals were distributed into two even lots. The batching of...

Selenium is an essential trace element that occurs in nature, in both inorganic and organic forms. This element participates in numerous biochemical processes, including antioxidant potential, but the mechanism of its anti-cancer action is still not well known. It should be noted that the anti-cancer properties of selenium depends on its chemical form, therapeutic doses, and the tumor type. Hig...

Aflatoxin B1 (AFB1), among other aflatoxins of the aflatoxin family, is the most carcinogenic and hazardous mycotoxin to animals and human beings with very high potency leading to aflatoxicosis. Selenium is an essential trace mineral possessing powerful antioxidant functions. Selenium is widely reported as an effective antioxidant against aflatoxicosis. By preventing oxidative liver damage, sup...

The bioconversion of selenium in the form sodium selenite (Na2 SeO3 ) (SeIV) or selenate SeO4 (SeVI) to organic by Lactobacillus casei (L. casei) was investigated vitro. MRS media supplemented with 1, 2, 5, 10 20 ppm Se, inoculated 2% starter culture about 105 cfu/ ml L. and then incubated up 24 hrs at 37o C. Increasing “Se(IV)” concentrations markedly reduced bacterial growth compared “Se(VI)”...

Three mixtures were used for wet digestions: nitric and sulphuric acids, 30 per cent. hydrogen peroxide and sulphuric acid, and selenium and sulphuric acid. In the nitric acid digestion 3 ml. of conceintrated sulphuric acid was used for each gram of dry plant material, a total of 50 inl. of concentrated nitric acid was added in four portions, the mixture being evaporated to white fumes and cool...

In the San Joaquin Valley, selenium concentrations in agricultural waste water have become a serious concern as an environmental pollutant causing birth defects and death in birds, small mammals, and fish. One method of lowering the concentration of selenium in the agriculture discharge is to use biological treatment. A pilot treatment system was developed at Panoche Drainage District using loc...
