Nitrification at Low pH by Aggregated Chemolithotrophic Bacteria.
A study was performed to gain insight into the mechanism of acid-tolerant, chemolithotrophic nitrification. Microorganisms that nitrified at pH 4 were enriched from two Dutch acid soils. Nitrate production in the enrichment cultures was indicated to be of a chemolithoautotrophic nature as it was (i) completely inhibited by acetylene at a concentration as low as 1 mumol/liter and (ii) strongly r...

متن کاملStudy of serum copper concentration in adult males working at Shahid Bahonar copper complex
In order to measure serum copper concentration, 163 adult males working at different units of copper plant from a total population of 671, were selected by simple random sampling. Eighty three subjects working at melting foundry, 49 in extrugen- rolling and 31 at administrative service untils. Eighty four adult male natives of Kerman and it's suburbs were randomly choosen as control group, seru...
متن کاملELECTROCHEMICAL BEHAVIOUR OF AISI 304 STAINLESS STEEL IN SULFURIC SOLUTION: EFFECTS OF ACID CONCENTRATION
The effects of H2SO4 concentration on the electrochemical behaviour of passive films formed on AISI 304 stainless steel were investigated using by potentiodynamic polarization, Mott–Schottky analysis and electrochemical impedance spectroscopy (EIS). Potentiodynamic polarization indicated that the corrosion potentials were found to shift towards negative direction with an increase in solution co...
متن کاملElectrochemistry of high concentration copper chloride complexes.
High concentrations of copper chloride solutions (in the molar range) are used in several industrial applications. In this work, we investigated the species distribution of copper chloride complexes and how to measure the copper concentration precisely at high concentrations using electrochemical methods, by including migrational effects. The latter, in fact, can be useful in determining the na...
