[Isolation, identification and characterization of a broad-spectrum azo-reducing Citrobacter strain AzoR-2].

A broad-spectrum azo-reducing bacterial strain, AzoR-2, was isolated from a active-sludge of textile-printing wastewater treatment plant and the strain was identified and characterized. This strain was identified as Citrobacter sp. according to its morphological, physiobiochemical characteristics and analysis of its 16S rDNA and beta-lactamase gene sequence.
