Isolation of arsenic-tolerant bacteria from arsenic-contaminated soil [PDF]

Songklanakarin Journal of Science and Technology (SJST), 2008
The disposal of toxic heavy metals such as arsenic posed high risk to the environment. Arsenite [As(III)], a reduced form of arsenic, is more toxic and mobile than arsenate [As(V)].

Arsenite Induced Disruption of Mitosis

, 2018
Arsenite is a known carcinogen that causes skin, bladder, and liver cancer. However, the mechanism of carcinogenesis is unknown. Arsenite (AsO2 - ) delays entry into mitosis by activation of the G2 checkpoint.

Protein Film Voltammetry of Arsenite Oxidase from the Chemolithoautotrophic Arsenite-Oxidizing Bacterium NT-26^†

, 2016
The chemolithoautotrophic bacterium NT-26 (isolated from a gold mine in the Northern Territory of Australia) is unusual in that it acquires energy by oxidizing arsenite to arsenate while most other arsenic-oxidizing organisms perform this reaction as ...

Cultivating efficiency: high-throughput growth analysis of anaerobic bacteria in compact microplate readers

Microbiology Spectrum
Anaerobic microbes play crucial roles in environmental processes, industry, and human health. Traditional methods for monitoring the growth of anaerobes, including plate counts or subsampling broth cultures for optical density measurements, are time and ...

Expression of the arsenite oxidation regulatory operon in Rhizobium sp. str. NT‐26 is under the control of two promoters that respond to different environmental cues

MicrobiologyOpen, 2018
Rhizobium sp. str. NT‐26 is a Gram‐negative facultative chemolithoautotrophic arsenite oxidizer that has been used as a model organism to study various aspects of arsenite oxidation including the regulation of arsenite oxidation.
