Reuse of waste beer yeast sludge for biosorptive decolorization of reactive blue 49 from aqueous solution

Abstract

Reactive blue 49 was removed from aqueous solution by biosorption using powder waste sludge composed of Saccharomyces cerevisiae from the beer-brewing industry. The effect of initial pH, temperature and the biosorption thermodynamics, equilibrium, kinetics was investigated in this study. It was found that the biosorption capacity was at maximum at initial pH 3, that the effect of temperature on biosorption of reactive blue 49 was only slight in relation to the large biosorption capacity (25°C, 361 mg g(-1)) according as the biosorption capacity decreased only 43 mg g(-1) at the temperature increased from 25 to 50°C. The biosorption was spontaneous, exothermic in nature and the dye molecules movements decreased slightly in random at the solid/liquid interface during the biosorption of dye on biosorbents. The biosorption equilibrium data could be described by Freundich isotherm model. The biosorption rates were found to be consistent with a pseudo-second-order kinetics model. The functional group interaction analysis between waste beer yeast sludge and reactive blue 49 by the aid of Fourier transform infrared (abbr. FTIR) spectroscopy indicated that amino components involved in protein participated in the biosorption process, which may be achieved by the mutual electrostatic adsorption process between the positively charged amino groups in waste beer yeast sludge with negatively charged sulfonic groups in reactive blue 49.

“…Recently, studies focused on microbial biomass as treatment by microorganisms is eco-friendly and cost effective [4,7]. Several bacteria [2,[8][9][10][11], yeast [12][13][14][15][16], algae [1,4,[17][18][19] and fungi [6,[20][21][22][23][24][25][26][27][28][29] have been used for dye removal from waste water and reported as potential bioadsorbents/biodegraders for toxic compounds. A summary of the most recent studies on reactive dye removal that performed with various microorganisms was presented in Table 1.…”

Biosorption of anionic textile dyes from aqueous solution by yeast slurry from brewery

“…Reduction of light penetration, which is essential for photosynthesis, difficult oxygen transfer, and alteration of aesthetic characteristics are some impacts from the disposal of colored waste into aquatic ecosystems (Juang et Adsorption is an efficient and economic process to remove pollutants from the wastewater. Activated carbon is the principal material used in the adsorption process but its high cost and problem with regeneration limit its application on a large scale (Malik, 2004;Chevalier et al, 2007;Wang and Guo, 2011). On the order hand, adsorption by biological material provides an alternative way for the bioadsorptive decolorization.…”

“…Consequently, waste beer yeast is produced in large quantities at low-cost, which makes it an interesting target for the examination of its dye biosorption potential. This waste has already been used efficiently to remove heavy metals like cooper, lead, chromium, nickel, zinc, cadmium, manganese, aluminum, and uranium (Riordam et al (Wang and Guo, 2011). However, bioadsorption studies on textile dyes using waste beer yeast may be unsatisfactory, mainly when it is found a high chemical diversity of dyes and application of waste beer yeast in form of slurry.…”
