BIODEGRADATION OF METHYLENE BLUE BY BACTERIA STRAINS ISOLATED FROM CONTAMINATED SOIL

Methylene blue is one of the textile dyes that are commonly used in coloring industry. The discharge wastewater containing residual substances into environment can lead to environmental pollution. Thus, bioremediation be a solution reduce dye pollution by using bacterial strains. In present study, two strains with ability degrade methylene were isolated from contaminated soil. Both bacteria further evaluated for decolorization percentage and effect abiotic parameters on growth. incubated mineral salt medium added eight days static aerobic conditions. degradation was examined UV-VIS spectrophotometer at 665 nm. identified as Klebsiella pneumoniae strain UMTFA1 (EK) Pseudomonas aeruginosa UMTFA2 (EP) 16s rRNA sequencing. biodegradation study showed capable 10.52% 11.65% after 8 incubation, respectively. may provide basis biotreatment dye-contaminated soils.
