Effect of Various Carbon and Nitrogen Sources on Decolorization of Textile Dyes by Pseudomonas taiwanensis Strain TNZ3

The co-substrate is a crucial component in the bio-decolorization process that helps bacteria to grow and carry out their fundamental functions. Different types of textile dyes with diverse chemical structures are frequently employed industry, most them resistant biodegradation because xenobiotic nature. Due low carbon content dyes, particularly azo co-metabolic conditions required for decolorization process. Hence, current study was aimed determine which striking nitrogen sources preferred generating decolorize following dyes: Disperse Yellow-3, Malachite Green, Basic Red-18, Reactive Blue-4. were used isolate, screen, evaluate different bacterial strains dye degradation. A potential strain Pseudomonas taiwanensis TNZ3 identified based on 16s rDNA sequence selected further study. It found presence yeast, peptone, NH4Cl, sucrose, glucose, fructose, maltose, galactose, lactose, starch contaminated media effectively enhanced degradation rate by TNZ3. In medium inoculated TNZ3, sucrose yeast peptone extracts induced greatest among sources. all maximum occurs at 1.5% extract supplementation. results made it abundantly clear various as co-substrates played effective role
