background: phosphorus is an indispensable element for the growth of animals and plants. there are several environmental problems related to phosphate; therefore, the technical and economic methods of removing phosphate are of great importance. this study evaluated the efficiency of polyaniline/ni0.5zn0.5fe2o4 magnetic nanocomposite in removing phosphate from aqueous environments. methods: the ...

the sources of groundwater pollution such as, industrial effluents, sewage and extensive farming have lead to agrochemical pollution. mathematical modeling helps to analyze the existing situation, allows forecasting, and to evaluate the effects of changes in the surrounding water quality. the present research has been focused mainly towards understanding the various processes affecting the tran...

abstracta pot study was conducted in order to evaluate the effect of plant growth promoting rhizobia (pgpr) on canola growth and ionic composition under salt stress conditions, was conducted as factorial in randomized complete block design with three replications. salinity in four levels of 0, 3, 6 &9 ds/m were evaluated with mixture of salts nacl & mgcl2. canola seeds were inoculated with sele...

Newly laid eggs of many insect species store maternal ecdysteroids as physiologically inactive phosphoric esters. In the silkworm Bombyx mori, we previously reported the presence of a specific enzyme, called ecdysteroid-phosphate phosphatase (EPPase), which catalyzes the dephosphorylation of ecdysteroid-phosphates to increase the amount of free ecdysteroids during early embryonic development. I...

Long-chain polyprenols and polyprenyl-phosphates are ubiquitous and essential components of cellular membranes throughout all domains of life. Polyprenyl-phosphates, which include undecaprenyl-phosphate in bacteria and the dolichyl-phosphates in archaea and eukaryotes, serve as specific membrane-bound carriers in glycan biosynthetic pathways responsible for the production of cellular structures...
