This bacterium, which was isolated from Lake Akkaya, (Nigde, Turkey), was able to completely degrade and mineralize the dye under anaerobic conditions with 100% efficiency. The degradation efficiency of this strain, in the presence and absence of a co-substrate was investigated. The biodegradation of the dye was monitored by UV-visible, (FTIR) spectroscopy and HPLC. From these analyses, a complete mineralization of the toxic aromatic ring system of the reactive red 195 dye was observed.eninfo:eu-repo/semantics/openAccessBiodegradationdecolorisationbiomineralisationazo dyereactive red 195Rhodopseudomonas palustrisArticle6112012610.5897/AJMR11.1059WOS:000306316000018N/A
