Investigation of reactive dye turquise blue HFG removal with lysinibacillus fusiformis B26 and detection of metabolites

Abstract

In this study, thermophilic bacterial strain from thermal region in Pamukkale (Denizli) displaying decolorization capability was isolated. Lysinibacillus fusiformis B26 exhibited capability decolorization and degradation of Turquise Blue HFG (an initial concentration of 50 mg/I, starch, peptone from casein) within 34 h at temperature 50 °C and pH 7.5. Biosorption capacity obtained from L. fusiformis B26 was 2.97%. GC-MS and FT-IR results indicate that one remarkable metabolite (diethyl phthalate) was detected at the end of degradation process. Consequently, Turquise Blue HFG textile dye was biotransformed by Lysinibacillus fusiformis B26. © by PSP.
