Arsenite oxidase also functions as an antimonite oxidase.
Arsenic and antimony are toxic metalloids and are considered priority environmental pollutants by the U.S. Environmental Protection Agency. Significant advances have been made in understanding microbe-arsenic interactions and how they influence arsenic redox speciation in the environment. However, even the most basic features of how and why a microorganism detects and reacts to antimony remain ...
متن کاملApplication of internal standard method in recombinant luminescent bacteria test.
Mercury and its organic compounds have been of severe concern worldwide due to their damage to the ecosystem and human health. The development of effective and affordable technology to monitor and signal the presence of bioavailable mercury is an urgent need. The Mer gene is a mercury-responsive resistant gene, and a mercury-sensing recombinant luminescent bacterium using the Mer gene was const...
متن کاملAnalysis of bioavailable phenols from natural samples by recombinant luminescent bacterial sensors.
A whole-cell recombinant bacterial sensor for the detection of phenolic compounds was constructed and used for the analysis of bioavailable phenols in natural samples. The sensor Pseudomonas fluorescens OS8(pDNdmpRlux) contains luxCDABE operon as a reporter under the control of phenol-inducible Po promoter from Pseudomonas sp. CF600. Expression of lux genes from the Po promoter, and thus the pr...
متن کاملA suite of recombinant luminescent bacterial strains for the quantification of bioavailable heavy metals and toxicity testing
BACKGROUND Recombinant whole-cell sensors have already proven useful in the assessment of the bioavailability of environmental pollutants like heavy metals and organic compounds. In this work 19 recombinant bacterial strains representing various Gram-positive (Staphylococcus aureus and Bacillus subtilis) and Gram-negative (Escherichia coli, Pseudomonas fluorescens) bacteria were constructed to ...
