Our works can be used in agriculture, medical, food productions and industries. Also the media have been modified to increase the production of polyglutamic acid more than the commercial media. The product of polyglutamic acid has been purified and tested for its solubility in different solvents and exposed to irradiation in order to enhance its ability to use as hydro gel especially in agriculture.

The presence of Helicobacter pylori in sewage water was confirmed, thus there is a reservoir for H. pylori outside of the human stomach. In aquatic environment, this bacterium transforms from the characteristic bacillary form to coccal or cocco-bacilli form, which is non culturable. However, Culturing this bacterium for the first time by the use of MDCS method took place. Here is a similarity between H. pylori found in sewage and those obtained from clinical biopsy and drinking water as indicated by RFLP technique raising the possibility for a fecal-oral route of transmission

Three genera of bacteria(Deinococcus radiodurans, Shewanella oneidensis, and Bacillus thuringiensis)have been isolated from soils in Basra- Iraq. These bacteria showed high tolerance for Pb and Cd with the possibility of being exploited in bioremediation in two routes, bioaccumulation and biosorption.The three types of bacteria have biosorption ability exceeding their bioaccumulation ability. In bioaccumulation experiments, TEM has been decisive in showing these bacteria of differed abilities to accumulation Pb and Cd. Appling of the advanced tools of FTIR and XRD has been crucial for...
