Preliminary Studies On Biodecolorization Of Reactive Red 35 By Pseudomonas Aeruginosa Arsks20
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 8
Abstract
Pseudomonas aeruginosa ARSKS20, an antibiotics sensitive strain could decolorize Reactive Red 35(RR35) dye up to 95% with 8.27 mg l-1 h-1 at 40°C, pH 8, under static condition at 100 mg l-1 concentration. Yeast extract at 5 g l-1concentation and with 5% inoculum volume was proved as an optimum for dye decolorization. It can tolerate 50 g l-1 NaCl concentration and decolorized 90% RR35. Pseudomonas aeruginosa ARSKS20 could efficiently decolorized RR35 (100 mg l-1) up to twelve repeated dosing without supplementation of new nutrients. HPLC analysis confirmed the biodegradation of RR35. The Less toxic nature of the dye degraded products was observed by microbial toxicity assay of agricultural important bacteria.
