title: A rapid colony screening method for the detection of arsenate-reducing bacteria.
abstract: A rapid and simple method has been developed for the detection of arsenate reducing bacteria based on the presence of arsenite [As (III)], the end product of anaerobic arsenate [As (V)] respiration. Confirmation of As (III) product is made by the reduction of starch-iodine complex. The method can be used over a large pH range (5.5-9.0) and can easily be determined at arsenite concentration as low as 0.025 mM. Major advantages of this technique are that a large number of samples can be analyzed easily at a time.
