Experimental eradication of heavy metal ions via bacteriocin TXJ for Lactobacillus salivarius strain from greek yogurt

Pollution in general is constantly increasing being polluted by environmental pollution with heavy metals that may be located in air, soil, water, or even food. In spite of being bacteria in general are harmful to humans, they are sometimes considered very valuable and safety, especially in biological treatment like probiotic bacteria group. Lactobacillus salivarius one of the maximum essential sorts of microorganism which are harmless to human and that may be play very capability position to cast off and removal heavy metals in different media. The main object in this study is extract bacteriocin TXJ for  Lactobacillus salivarius isolated from Greek yogurt, which performs very important function by experimentally in biological reaction to the different heavy metal ions and reduce their concentrations and hopefully to using in the near future for treatment and reduce the pollution in the environment. This project there were used three various concentrations 20, 40, 60 PPM for five main heavy metals (Cu, Cd, Pb, Cr and Zn), which were added to extracted bacteriocin. Atomic absorption technique was used for determine the levels of heavy metal. Furthermore, the experiment was recorded based on the comparison for before and after adding bacteriocin protein at the lab.&nbsp
