The most probable number (MPN) of total coliforms bacteria were determined by multiple tube fermentation technique. Separate sets of 10 tubes of Lauryl Tryptose Broth (LTB) were prepared and inoculated each set of 10 tubes of double strength LTB with 10 ml of the water sample. These LTB tubes along with inverted Durham tubes were incubated at 35 ± 0.5°C for 24 and 48±2 h after inoculation. Tubes were examined for gas production at the end of 24/48 h incubation. Gas production was measured by gas displacement in the inverted vial and also effervescence produced when the tube was gently shaken. Positive tubes with gas formation and turbidity were sub-cultured into BGB (Brilliant Green Lactose Bile broth and E.C. Broth having 10ml broth with inverted Durham tubes by means of 3 mm loop). All BGB tubes were incubated at 35 ± 0.5°C for 48±2 h and E.C. Broth tubes at 44.5±.01°C for 24±6 h and examined for gas production. Total coliforms and fecal coliforms were calculated from MPN tables.
