Abstract :
New bacteria that was provided from contaminated soils surrounding the coal, aluminum, salt mines and wetland separated, synthesized and characterized. The achievements show that this soils and waters have five disposed bacteria consist of Microbacterium SP, Micrococcaceae Bacterium, Planomicrobium SP, Brevndimonas Aurantiaca and Halomonas SP. Secondly, the result of the potential of removal activity study of new bacteria, with respect to basic blue 41 and disperse red 177 dyes are presented. So, in the batch system the influence of pH, bacteria dosage, temperature, dyes initial concentration and time was investigated. Finally, the study of removal mechanism show that the biodegradation is the governing mechanism. So, we can confirmed that these natural and locally available bacteria showed a great efficiency for the removal of dyes from the aqueous solution without any unsafe byproduct, also can be utilized for other water pollutants.
