Isolation and identification of high fluoride resistant bacteria from water samples of Dindigul district, Tamil Nadu, South India.

ABSTRACT: Fluoride (F ^- ) pollution is one of the major issues in India and worldwide. Water samples were collected, and analyse the physicochemical characteristics. From the results, acceptable limit pH ranges, low and high electrical conductivity (EC) values, high-level of TDS (total dissolved solids) and chloride (Cl^-) values, less than desirable and higher than permissible F ^- concentrations (4.7 and 11 ppm) were found. At first, ninety-three colonies were screened using rapid hicoliform agar plates. After that, sixty-six F ^- resistant colonies were picked up from 50  mM NaF (Sodium fluoride) containing LB agar plates. Finally, eight isolates were showing a high degree of F ^- resistance (200--300 mM NaF) and selec
