Minimum Inhibitory Concentration (MIC)
MIC of the 16 most potential bacteria ranged from 500 -1100 mgL1 for arsenate (V) and 100-600 mgL1 for arsenite (III). Out of 16 arsenic tolerating bacteria, NR5 exhibited maximum tolerance i.e. 1100 mgL-1 against As (V) followed by NR1, MB1, MA7 and MA8 (1000 mgL-1) (Table 2). As (III) tolerance of NR5, NR1 and MB 1 was recorded as 400mgL-1 followed by MA7 (200 mgL-1).
