Case Study

Bacterial decolorization and degradation of the dye Reactive Red 180

Wang, Hui, et al. International Biodeterioration & Biodegradation 63.4 (2009): 395-399.

A strain CK3 was isolated from activated sludge collected from a textile mill and showed significant decolorization ability for the reactive textile dye Reactive Red 180. Phenotypic characteristics and phylogenetic analysis of 16S rDNA sequences indicated that the strain belonged to the genus Citrobacter. The bacterial isolate CK3 showed strong decolorization ability for various reactive textile dyes. Anaerobic conditions of 4 g glucose, pH=7.0 and 32°C were considered to be the optimal decolorization conditions. Citrobacter CK3 grew well in high concentrations of dye (200 mg/l) with a decolorization degree of about 95% within 36 h and could tolerate dyes up to 1000 mg/l. UV-visible spectrophotometer analysis and colorless bacterial cells indicated that Citrobacter CK3 exhibited decolorization activity through biodegradation rather than inactive surface adsorption.
Aliquots (10 g) of the collected activated sludge were inoculated into 100 mL of modified M9 liquid medium (NaHPO3, KHPO3, NH4Cl, NaCl, MgSO4, CaCl4, glucose, VB and Reactive Red 180, pH 7.0), then incubated at 32°C under static conditions for 5 days and then transferred to fresh liquid medium. This process was repeated about five times until the medium was decolorized. The samples were then serially diluted tenfold and aliquots of 100 mL of each dilution were spread on modified M9 agar plates containing 50 mg/I Reactive Red 180. After incubation at 32°C for 24 h, morphologically different colonies were streaked on M9 agar for purification before inoculation into liquid medium to check their decolorization ability. The strain with the strongest decolorization ability was isolated and named CK3, and stored in LB medium containing 10% glycerol at 70°C.

Catalytic mineralization of reactive red 180

Kuriechen, Selma K., et al. Chemical Engineering Journal 174.2-3 (2011): 530-538.

The photocatalytic degradation of reactive red 180 (RR180), a monoazo textile dye, was studied using titanium dioxide (TiO2) aqueous suspension under visible light irradiation. The photocatalytic degradation was monitored by measuring the decolorization rate and the reduction in total organic carbon content during the reaction. The effects of catalyst concentration, substrate concentration, solution pH, and the addition of electron acceptors, potassium peroxodisulfate and potassium peroxymonosulfate on the photocatalytic degradation of RR180 prepared by colloidal titanium dioxide were also studied. The photocatalytic degradation rate was found to be dependent on the ratio of TiO2 to dye. The addition of peroxidase to the TiO2-RR180 system increased the degradation rate by about 10 times and was found to be promising for the degradation of reactive red 180 compared to other electron acceptors. About 80% of the dye was mineralized within 5 h by visible light photocatalytic degradation in the presence of TiO2 and oxone.
A known amount of reactive red 180 dye was dissolved in 70 mL of double distilled water in a photoreactor. Similarly, a known amount of photocatalyst (i.e., TiO2) was then added to the dye solution followed by the addition of the oxidant. The aqueous suspension was mixed continuously for 45 min in the dark before starting the irradiation to ensure adsorption/desorption equilibrium. Under this condition, the dye concentration in the bulk solution (measured by the absorbance of the dye at ε = 542 nm; ε = 19,466 Mcm) was used as the initial concentration (C) for further kinetic analysis of the photodegradation process. During the irradiation process, 5 mL aliquots were removed at appropriate time intervals and immediately removed the photocatalyst by centrifugation and syringe filter filtration. The concentration obtained at a certain irradiation time (t) is denoted as C. The decrease in dye concentration was determined using a UV-visible spectrophotometer by tracking the absorbance of the transparent dye solution at its temperature. Since no changes in shape and peak position and no new peaks were observed in the absorption spectrum of RR180 during the degradation process, the absorbance is proportional to the concentration of the dye.

Decolorization of Reactive Red 180 dye and dye wastewater containing Reactive Red 180 was studied

Raja, R., et al. International Journal of Research and Analytical Reviews 6.2 (2019): 818-825.

The degradation of Reactive Red 180 dye and dye wastewater containing Reactive Red 180 dye was studied using H2O2 solar assisted photodegradation process. The photodegradation process was carried out in a 250 ml conical flask with side arm with dye solution of 100 mg/l containing 50% H2O irradiated with solar light in the lux intensity range of 60000-90000 lux. 100% decolorization was achieved in RR-180 dye and 75% diluted wastewater containing RR180 with a decolorization of 96.18%. The best results were achieved in undiluted effluent containing RR-180 under the optimum reaction conditions. Complete decolorization of RR-180 dye and effluent containing RR-180 requires an optimum pH of 7 and H2O2 concentration of 700 mM. Therefore, H2O2/sunlight proved to be a more suitable decolorization method for the azo dye Reactive Red-180.
Experiments were performed on dye solutions containing 100 mg/l Reactive Red 180. 110 ml of 50% concentration was used in a volume of 3 ml. The dye solution was placed in a 250 ml conical flask with a side arm along with 3 ml 50% H2O2 and irradiated with sunlight. The light intensity was fixed in the range of 60000-90000 lux and its intensity was measured using an illuminometer. The illumination intensity was measured in the range of 200-200000 lux using an illuminometer. Decolorization was demonstrated by measuring the absorbance of the decolorized dye solution at time intervals of 1 or 1.5 hours using a colorimeter.

Decolorization study of reactive red 180 by laccase

Cristóvão, Raquel O., et al. Book of Abstracts of the 10th International Chemical Conference and Biological Engineering Conference-CHEMPOR 2008.

A three-level Box-Behnken factorial design with three factors and response surface methodology were used to remove commercial reactive red 180 using laccase. A mathematical model was developed to investigate the effects of temperature, pH, enzyme concentration and their interactions on decolorization. Enzyme concentration and pH and their interactions were the main factors affecting decolorization. Dye degradation was independent of temperature. The model estimated that the highest decolorization (> 92%) was obtained at pH 7.5 and 85 Ul. This prediction was experimentally validated with a dye color removal of 93 ± 1.5% at 540 nm.
To study the decolorization of reactive textile dyes, reactive red 180 was incubated in a 25 ml conical flask with stirring for one day. The dye degradation conditions were: laccase concentration (24, 48 and 96 Ul), temperature (25, 35 and 45 °C) and pH (6, 7 and 8). The pH of the dye solution was adjusted with 50 mM phosphate buffer. Dye decolorization was determined by monitoring the decrease in the absorbance peak at the wavelength of maximum absorbance of Reactive Red 180 (540 nm) (Peak) or by calculating the total area across the entire visible spectrum (Area). All experiments were performed using a UV-Vis spectrophotometer.
