Decolorization of irgalite dye by immobilized Pseuodomonas putida on activated carbon, prepared from agriculture waste

Abstract

A carbon sorbent derived from an agriculture waste, mustard straw was applied to study the removal of irgalite dye from aqueous solution. Comparative study on adsorption and simultaneous adsorption and biodegradation (+) of irgalite dye using Pseuodomonas putida (MTCC 1194) with activated carbon prepared from mustard straw showed removal of 83.3% higher SAB, with respect to adsorption (70%). For biodegradation of irgalite by P. putida at shake flask level Haldane's growth model fitted the best.

Key words: activated carbon, Pseudomonas putida, adsorption.
