Possible bioremediation of arsenic toxicity by isolating indigenous bacteria from the middle Gangetic plain of Bihar, India.

ABSTRACT: In middle Gangetic plain, high arsenic concentration is present in water, which causes a significant health risk. Total 48 morphologically distinct arsenite resistant bacteria were isolated from middle Gangetic plain. The minimum inhibitory concentration (MIC) values of arsenite varied widely in the range 1-15 mM of the isolates. On the basis of their MIC, two isolates, AK1 (KY569423) and AK9 (KY569424) were selected. The analysis of the 16S rRNA gene sequence of selected isolates revealed that they are belong to the genus Pseudomonas. The AgNO₃ test based microplate method revealed that isolates, AK1 and AK9, have potential in transformation of arsenic species. Further, the presence of aoxR, aoxB and aoxC genes in the both isolated strain AK1 and AK9 was co
