For FPase activity, 50 mg of Whatman no. 1 filter paper was used as a substrate. Crude culture filtrate was used as an enzyme sample diluted in 0.05 M sodium citrate buffer (pH 4.8). The reaction mixture contained 0.5 ml of culture filtrate, 1.0 ml of 0.05M sodium citrate buffer (pH4.8) and substrate was incubated at 50°C for 60 min for enzymatic reaction. After incubation, 3 ml of DNS was added and heated for 5 min in a boiling water to obtain a colored reaction mixture. In enzyme blank, enzyme sample was added after DNS. Absorbance of the solution was measured at 540 nm using UV-VIS spectro-photometer.
