The recycling of electronic scrap is an important subject not only from environmental aspect but also for recovering metal resources such as copper. In this work, the microbial extraction copper and other metals (Cu, Ni, Co, Fe Al) present in depopulated shredded printed circuit board (PCB) elaborated. Bacterial strains A. ferrooxidans, thiooxidans a fungal strain, niger are used along with PCB...

fabrication of ultrafine grained materials by imposing severe plastic deformation for improvement of mechanical and physical properties of metals has been the focus of many researches over the past few years. in this process, a sheet is subjected to repetitive shear deformation conditions by utilizing asymmetrically grooved and flat dies through alternate pressing. in this study, a 2mm thick co...

Abstract Three mixed ligand complexes of sulphamethoxazole and citric acid have been synthesized using Mn(II), Fe(III) Ni(II) chlorides. The were characterized by elemental analysis, melting point, conductivity test, magnetic measurement, UV-Visible infrared spectroscopy. spectra data revealed that the ligands act as bidentate, in which coordinate through C=O carboxyl oxygen hydroxyl groups, wh...

Improvement of deformability for Mg-based composite materials with a dispersion of Ti particles has been considered in terms of the strain transfer through the interface, but is not fully understood during the deformation of ductile Ti particles. Mg-based composites composed of pure Mg and pure Ti plates was investigated to clarify the strain transfer through theMg/Ti interface using crystallog...

Identification and typing of spoilage and pathogenic microorganisms have become major objectives over the past decade in microbiology. In food, strain typing is necessary to ensure food safety and for linking cases of foodborne infections to suspected items. Recent advances in molecular biology have resulted in the development of numerous DNA-based methods for discrimination among bacterial str...

Strain PA-1 (S. Barik, W.J. Brulla, and M.P. Bryant, Appl. Environ. Microbiol. 50:304-310, 1985) is an anaerobic, gram-negative rod that in pure culture decarboxylates succinate to propionate and that grows syntrophically as an acetogen with the H2 utilizer Methanospirillum hungatei if glucose, pyruvate, aspartate, or fumarate is provided. In pure culture, strain PA-1 grows optimally in a mediu...

Development of MMRS (modified MRS Agar) culture medium; the absolute vegetarian culture medium containing plant seed powder in place of beef extract for the growth of probiotics. Vegetarian probiotic foods by definition must be free from all animal-derived ingredients. This research provides an alternative efficacious, cost effective vegetal culture medium. The culture medium developed in prese...
