Removal of mercury from chloralkali electrolysis wastewater by a mercury-resistant Pseudomonas putida strain

Article Abstract:

Microbial mercury removal using a mercury-resistant Pseudomonas putida strain, Spi3, is a potential biological treatment for chloralkali electrolysis wastewater. Treatment of actual chloralkali electrolysis factory effluents with a mercury-resistant P. putida strain isolated from polluted river sediments has been studied using a stepwise approach. Chloralkali wastewater from several plants in Europe was studied so that a system could be tailored to each condition. NaCl was the most common copollutant and interferes with mercuric reductase activity.

Effect of oxygen on formation and structure of Azotobacter vinelandii alginate and its role in protecting nitrogenase

Article Abstract:

Research reveals in Azotobacter vinelandii nitrogenase protection is mediated by alginate. Results demonstrate depending on the oxygen tension in the culture medium, alginate composition varies and an alginate capsule on the cell surface functions as a barrier for oxygen diffusion into the cell.

Structure and species composition of mercury-reducing biofilms

Article Abstract:

Analysis of the bacterial strains in the mercury-reducing biofilms from packed-bed bioreactors indicate that majority of them show mercury resistance. Thermogradient gel electrophoresis data reveal that the biofilms contain cultivable effluent bacteria.
