Özet

Azo dyes are one of the biggest class of the colorants and their removal from wastewater is still a problematic issue. Bioremoval presents an inexpensive and efficient alternative to conventional removal techniques and efficacy of the process can be increased significantly with supplementation of certain chemicals, such as polymers or surfactants. In this context, the effect of the surfactant sodium dodecyl sulfate on the bioremoval of Cu (II) by the yeast Kluyveromyces marxianus was investigated and found as 83% from the medium containing 25 mg/L Cu (II) and bioremoval yield was increased to 98% when the medium contained 0.1 mmol/L sodium dodecyl sulfate. The optimum conditions for Cu (II) bioremoval were observed in the presence of 25 mg/L initial Cu (II) and 0.1 mmol/L SDS at pH 6 when the agitation speed was 100 rpm and temperature was 30 degrees C. This study showed that surfactant aiding provides a remarkable strategy for Cu (II) bioremoval by K. marxianus.
