A STUDY OF BIODEGRADATION OF PAPER WASTES BY USING BACTERIA ISOLATED FROM THE SOILDHUHA MAHDI JABIR AND MUSTAFA MAHDI JABIRAbstract Ten soil samples have been collected randomly from local agriculture soils in Diwaniya city then the dilution 10-5 celtured in nutrient agar after mixing with 1 g of paper wastes after 90 days incubation at 35° C the resulted bacteria hydrolysis the paper and gave a zone of clearance about 13 -3 mm then the growing bacteria have been cultured alone on carboxymethylcellulose (CMC )agar .after incubation period and biochemical test there were three genus of bacteria recognized Pseudomonas florescence, E.coli and Bacillus subtillus. The study also observed that Pseudomonas florescence gave the highest diameter of zone of clearance 15 mm while E. coli gave the lowest zone of clearance, 5 mm.
