“…They reported removal of NH 3 was affected by the presence of azo dye (acid black 1) in a sequencing batch reactor. Besides that, the azo dye also affects the ammonium oxidizing bacteria (Topaç et al, 2009). The increasing trend of NH 3 -N in effluent may due to the conversion of azo bond in MO to NH 3 -N. Gavril et al (2007) suggested that the biodegradation of azo bond in Amaranth by white-rot fungus Trametes versicolor may either transformed to N 2 or NH 3 or incorporated into biomass.…”

“…Azo dyes are mutagenic and carcinogenic which impacts on man and the environment (Alves de Lima et al, 2007;Topaç et al, 2009). The most common drawbacks listed out in physical and chemical treatments of azo dyes are unable to completely remove, causing secondary pollutant and economically unfeasible.…”

BACKGROUND: Calcination significantly increased the adsorption performance of alunite for Acid Red 88. RESULTS: The adsorption properties of calcined alunite for Acid Red 88 were investigated. pH, adsorbent dosage, contact time and ionic strength were found to influence the adsorption. Temperature did not significantly affect the process. Kinetic data obey a pseudo‐second‐order model, while intraparticle diffusion is not the only rate‐limiting step. The Langmuir isotherm well described the equilibrium data. The monolayer adsorption capacity of calcined alunite was found to be 832.81 mg g−1. It was successfully used for the removal of dye in continuous mode at a flow rate of 4.0 mL min−1. Co‐anions affected the adsorption capacity of calcined alunite but the presence of other organic compounds in the same medium did not significantly change the adsorption performance. Reusability studies showed that the calcined alunite can be reused four times. Electrostatic interaction, ion‐exchange and complexation were found to be effective mechanisms for the adsorption of Acid Red 88 by calcined alunite. CONCLUSION: This study demonstrated that calcined alunite has excellent adsorption performance and might be a very good adsorbent for Acid Red 88 as an abundant, economical and practical material. © 2012 Society of Chemical Industry

“…Topaç et al (2009) reported that the existence of sulfanilic acid > 8 -1 mg kg dry soil could decrease the number of several bacteria. On the other hand, C. indologenes were more resistant to sulphanilic acid and may be able use this compound as C, N, and energy sources.…”

Previous work showed that Enterococcus faecalis ID6017 and Chryseobacterium indologenes ID6016 were able to decolorize the orange II qualitatively. In that experiment, E. faecalis could decolorize orange II more rapidly than C. indologenes. The objective of this study was to examine the decolorization of orange II by mixed culture and the growth of both bacterial species on orange II containing medium. The experiment was done in 500 mL sterilized Erlenmeyer flasks containing 285 mL growth media with 80 mg L-1 orange II. Five different treatments were performed in this project, i.e. medium was inoculated with (i) 15 mL of sterile aquadest, (ii) 15 mL of C. indologenes, (iii) 15 mL of E. faecalis, (iv) 7.5 mL of C. indologenes and 7.5 mL of E. faecalis, and (v) 7.5 mL of E. faecalis until decolorization occured , followed by inoculation with 7.5 mL of C. indologenes. Bacterial growth (total cells number), orange II, glucose, and suphanilic acid, as intermediate product of orange II decolorization, concentrations were measured every 2 h.The maximum decolorization of orange II was observed in the medium inoculated with a mixed culture of E. faecalis and C. indologenes. Decolorization of orange II occurred of growth and gave final concentration of sulphanilic acid of 7.06 mg L-1. During culture both species grow in equilibrium in terms of population
