EVALUATION OF ALKALINE PECTIN LYASE OF PSEUDOMONAS SP.FOR TEXTILE INDUSTRY EFFLUENT MANAGEMENTRITU SAHARAN AND KANTI PRAKASH SHARMAAbstract Pectin is a heteropolysaccharide present in plant cell wall. It provides mechanical strength to the plants and acts as a barrier for plant pathogens. Pectin imposes various problems to textile industries related with finishing and dyeing process. Pectin removal by traditional methods utilizes strong acid and alkali which generates toxic effects on the ecosystem. An alternative way to remove pectin is the use of biological methods which are comparatively safe to the environment.These methods are dependent upon the use of enzymes involved in pectin degradation. In the present study, alkaline pectin lyase of Pseudomonas sp. was isolated from diseased leaves of Cyamopsistetragonobola. The enzyme was found suitable for bio scouring of cotton fabric as it resulted in reduction of COD and BOD values of textile effluent. To the best of our knowledge this the first report of Pseudomonasâs pectin lyase application towards bio scouring of cotton fiber.
