Abstract
Five species of bacterial genera namely Pseudonionas, Micrococcus, Bacillus, Serratia and Proteus sp. and five species of fungi namely Aspergillus niger, Trichoderma liarzianurn, Myrothecitun roridilin, Curoularia luizata and Fusarium oxysporurn were isolated from the agricultural crop residues in the field soil by the conventional serial dilution plate technique. Cellulolytic activity of these organisms were determined by viscometric method and loss in dry weight of filter paper disc method. Among the five bacterial genera, Pseudonionas and Serratia sp. showed more cellulolytic activity than other bacteria whereas T'. harizianum and C. lunata showed more percentage loss in dry weight of the filter paper. All the ten species are cellulose degrading organisms with varying potentiality and the results are discussed.
