Abstract

Textile industry is one of the major causes of the contaminator of environment. It produces enormous amounts of diverse complex chemical substances as a part of vacant materials that includes dye in the form of wastewater throughout various stages of textile processing. These dyes produces the obvious aesthetic belongings to ecosystem by affecting on the photosynthetic ability of plants and are also toxic to the aquatic flaura and fauna when released in water system and thus ultimately get into food chain. In the present research study, Pseudomonas sp. GYH-1 was isolated and identified by 16s rRNA sequencing and phylogenetic relationship as a potent candidate to remove textile dye Golden Yellow HER from polluted soil and water samples. The physico-chemical activities of this isolate revealed maximum decolorization at 37°C at pH range 6.0–8.0 within 24 hours. The FT-IR and GC-MS analysis reports confirmed that complex dye was degraded into simple products. Further phytotoxicity and Microbial toxicity studies revealed that the byproducts formed after dye degradation were non-toxic to Jawar and Mung beans and other Microorganisms. Thus it can be concluded that Pseudomonas sp. GYH-1 may be used effectively for the removal of Golden Yellow HER from textile dye stuff waste.
