Previously, we found that arsenite (AsIII) oxidation could improve the generation of ATP/NADH to support the growth of Agrobacterium tumefaciens GW4. In this study, we found that aioE is induced by AsIII and located in the arsenic island near the AsIII oxidase genes aioBA and co-transcripted with the arsenic resistant genes arsR1-arsC1-arsC2-acr3-1. AioE(More)
A Gram-staining-negative, rod-shaped, motile by gliding and facultative anaerobic bacterial strain, YS-25T, was isolated from a sludge of a manganese mine. Phylogenetic analysis based on 16S rRNA gene sequences revealed that strain YS-25T formed a single branch within the strains of the family Sphingobacteriaceae and showed low similarities to Pedobacter(More)
A Gram-stain-positive, strictly aerobic, non-motile and rod-shaped bacterial strain, designated YS-17T, was isolated from soil in the Lengshuijiang antimony mine, Hunan Province, China. Comparative 16S rRNA gene sequencing analysis clustered it with Flavihumibacter strains, and strain YS-17T was most closely related to Flavihumibacter cheonanensis WS16T(More)
Some arsenite [As(III)]-oxidizing bacteria exhibit positive chemotaxis towards As(III), however, the related As(III) chemoreceptor and regulatory mechanism remain unknown. The As(III)-oxidizing bacterium Agrobacterium tumefaciens GW4 displays positive chemotaxis towards 0.5-2 mM As(III). Genomic analyses revealed a putative chemoreceptor-encoding gene, mcp,(More)
