%X Cellulolytic activities of bacterial and fungal isolates obtained from poultry droppings were determined using the ability of each isolate to produce clear zones on Carboxyl Methyl Cellulose Agar plates. The bacterial isolates were Klebsiella, Streptococcus, Celulomonas, Escherichia coli and Micrococus species. The cellulolytic counts ranged from 5.02 x 104 + 3.42 to 7.20 x 109 + 6.12 cfu/g. The cellulolytic activities of the bacterial isolates ranged from 0.04 to 0.26 iu/m with Cellulomonas having the highest cellulose activity. The fungal isolates were Aspergillus niger, Mucor mucedo, Trichoderma sp. and Penicllium chrysogenum with cellulose activities of 0.24 + 0.021 0.19 + 0.031, 0.23 + 0.05 and 0.23 + 0.028iu/ml respectively. All the isolates were able to degrade the sawdust to varying extent. The percentage degradation was highest with Micrococcus sp. (78.20%) and least with Trichoderma sp. (65.83%). The study shows that is a potential source of cellulolytic microorganisms which could be employed in the degradation of sawdust.
