REMOVAL OF DYES IN TEXTILE EFFLUENT USING BITTER GOURD, POTATO AND BRINJAL ENZYMES

In this study an effort has been made to use per oxidases enzyme of bitter gourd (momordica charantia) and plant polyphenol oxidases enzymes of potato (solanum tuberosum) and brinjal (solanum melongena) for the treatment of various important dyes used in textile industries. Potato, brinjal and bitter gourd is a commonly available plant in India. The primary objective of this study is to evaluate the efficacy of peroxidase and poly phenol oxidases enzymes in the degradation of dyes present in textile effluents under various experimental conditions like pH, Time intervals and Enzyme concentration on the basis of the one-factor-at-a-time (OFAT) method. And also evaluated the physico-chemical parameters of effluent after addition of enzyme extract. The maximum decolourisation of bitter gourd, potato and brinjal enzyme activity was achieved at pH 6.0, 10.0 and 3.0 with 4, 2 and 3 hrs of incubation and with an enzyme concentration of 0.8,0.6 and 1 ml. The maximum decolourisation percentage obtained by potato enzyme extract is 95% and hence this study results demonstrate that, among these three enzyme extracts the potato (Solanum Tuberosum) poly phenol oxidase enzyme is an effective biocatalyst for the treatment of effluents with dyes from textile industries and also most of the physico-chemical parameters values has also been reduced after addition of this enzyme extract.
