Heterologous production and characterization of bacterial nickel/cobalt permeases.

Dissolution of Nickel and Cobalt from Iron-Rich Laterite Ores Using Different Organic Acids

Due to the decreasing production of nickel and cobalt from sulfide sources, the Ni and Co extraction from the oxide ores (laterites) have become more prevalent. In this research work, the effects of calcination prior to leaching, acid concentration, percent solid, pH, and stirring speed on the nickel and cobalt recoveries from an iron-rich laterite ore sample were investigated using diffe...

COMPARATIVE CHARACTERIZATION OF PORINS FROM SALMONELLA TYPHIO-901 AND SALMONELLA TYPHIMURIUM RA-30

Porins from Salmonella typhi 0-901 and Salmonella typhimurium Ra-30 were characterized and compared. The elution profile of porins from these salmonella species on Sepharose-48 and HPLC appear to be very similar. The findings were confirmed by the electrophoretic pattern which showed three types of porins, i.e. OmpC, OmpD and OmpF in both species. These porins appear to be similar, if not ...

Characterization of the Inducible Nickel and Cobalt

Chronic and acute effects of nickel and cobalt on chlorophyll a and carotenoids of marine micro algae Nannochloropsis oculata

Algae are among the aquatic organisms that are severely exposed to increasing levels of pollutants, which are becoming a concern in marine ecosystems. Heavy metals are among the compounds for which their increase in high levels causes problems in the structure of algae communities in aquatic ecosystems. In this study, the effect of different concentrations of Nickel (1.5, 3, 4, 6, 8, 12, 15 mg/...

Synthesis and characterization of Co3(Po4)2 and Ni3(Po4)2 composite membranes based on PVC: A Comparative electrochemical studies through aqueous electrolyte solutions

The mechanical stability is an important phenomenon which governs many applications based properties of membranes. The inorganic materials of membrane may have been synthesized by qualitative the novel sol-gel or co-precipitation methods of material synthesis. The mMembranes of cobalt (CP) and nickel (NP) composites have been was designed by mixing of the polyvinyl chloride (PVC) with cobalt ph...
