Abstract
In this study heavy metals tolerance of bacterial isolates from efuent of metal processing industries was carried out. The microbiological analysis total of 6 industrial efuents samples were collected from various industries, and total of 42 isolates were obtained among these isolates were screed for heavy metals tolerance/resistance, among them one isolate SR6a (Achromobactor) was resistant to Cu at higher concentration (2000ppm) and considered as potential heavy metal resistance isolate. The some isolates such SR3f (Bacillus), SR4g (Achromobactor), SR5c (Bacillus), and SR3a (Pseudomonas) were multi heavy metal resistance ones. All these isolates from metal industrial efuents showed the heavy metal resistance against Copper, Nickel, Cadmium, Zinc and Mercury. the isolate SR6a identied as Achromobactor sp. was able to tolerate the heavy metal up to 3000 ppm concentration and can be very useful for the application in the environmental bioremediation.
