Abstract :

To decolourize congo red dye by soil bacterial isolates, Ecoli and streptococcus species. Soil sample collected from dyeing unit, Collectorate, Indore District, Madhya Pradesh for screening Congo red dye degrading bacterial isolates. Two bacterial isolates IS–1 and IS– 2 screened based on their ability to decolorize the Congo red , 1S–1 decolorized up to 94% followed by IS–2 with 91%. Both isolates were identified as IS–1 is E.coli species and IS–2 is streptococci species after microscopic and biochemical characteristics. Phytotoxicity test performed on two crop plants Vigna radiata and Cicer Arietinum for 10days. With phytotoxicity test, found that dye is toxic to the growth of agricultural crops, can treat polluted dye soil through micro–organisms, identified as a cost effective and environment friendly.
