Synergic treatment for monosodium glutamate wastewater by Saccharomyces cerevisiae and Coriolus versicolor

摘要

Biodegradation and decolorization of monosodium glutamate wastewater were carried out by using an acidophilus yeast strain of Saccharomyces cerevisiae and Coriolus versicolor. For the yeast treatment, the highest COD removal and reducing sugar removal efficiency were 76.6% and 80.2%, respectively. The color removal was only 2%. For C. versicolor treatment, the highest COD removal, color removal and reducing sugar removal efficiencies were 78.7%, 56.5% and 90.9%, respectively. The synergic treatment process, in which the yeast and C versicolor were successively applied,exhibited great advantage over the individual process. (c) 2006 Elsevier Ltd. All rights reserved.
