چکیده

halophilic and halotolerant microorganisms are good candidates for decolorization of azo dyeswhich are routinely used in the dyeing process in textile industries. in this paper, theoptimization of biological decolorization of synthetic dye solutions containing remazol black bby the previously isolated halophilic bacterium halomonas sp. d2 is investigated. in a primaryinvestigation using a one-factor–at-a-time method, temperature, initial ph of the solution, andconcentrations of glucose, yeast extract, and sodium chloride were chosen for optimizing dyeremoval using the taguchi method. based on the statistical analysis of the results, the mostsignificant parameter by far was the yeast extract concentration which accounted for 72.67% ofthe total effect, followed by ph (11.84%) and the nacl concentration (8.90%). the optimizedconditions for dye removal were predicted to be a temperature of 35°c, an initial ph of 10,glucose concentration of 1% (w/v), yeast extract concentration of 1% (w/v), and sodiumchloride of 10% (w/v). under these conditions, 95% decolorization was achieved in confirmingexperiments.

Study of decolorization variety by electrocoagulation process in the removal of Dye solution containing Remazol Yellow G: optimization of effective parameters using the Taguchi method

The Taguchi method was applied as an experimental design to determine optimum conditions for colour removal from azo dyes solutions containing remazol yellow G by electrocoagulation (EC) using iron and steel electrodes as anode and cathode, respectively. An orthogonal array (OA9) experimental design that allows to investigation the simultaneous variations of four parameters (initial remazol ye...

Screening, identification and optimization of a yeast strain, Candida palmioleophila JKS4, capable of azo dye decolorization

BACKGROUND AND OBJECTIVES Synthetic dyes are recalcitrant to degradation and toxic to different organisms. Decolorization of textile wastewaters is one of the major concerns since last decades. Physical-chemical treatments are very expensive and frequently producing large amounts of toxic wastes. Biological treatments can be more convenient. In the present study, an attempt has been made for de...
