    Abstract: Free living nitrogen fixing bacteria are those that lives freely on rhizosphere of a young growing plant or those living in a close association with root of plants (Rhizobacteria) but not symbiotically. In most tropical soil, Nitrogen and other essential nutrients element are the most limiting nutrients which deficiencies could lead to slow growth ... Show More

    Abstract: This study evaluates cellulose degrading bacteria isolates from paper mill dumpsites and their cellulolytic activity. Forty-one cellulose-degrading bacteria (CDB) were isolated from soil samples from seven different paper and pulp mill dump sites using enrichment method. The isolates were identified based on Morphology and Biochemical characterizat... Show More
