An attempt was made to isolate and study the cellulolytic microorganisms from
the soil under two deciduous (Tcctona grandis L. f. and Lagerstroeinia speciosa L.) and
two evergreen (Eucalyptus camaldulensis Dehnh. and Acacia auricul’iformis A. Cunn.
ex Benth.) forest plantations, and the relation of these organisms with the soil
nutrient of the forest (N, P, K and carbon) has been observed. Among the isolates,
finally selected 11 isolates comprised of one bacterial strain (Cellulonionas sp.), five
strains of Streptomyces and five fungalstrains (Aspergill usflavus, A. nigcr,A.ochraceous,
Trichodernia lignorum, T. glaucum). Cellulolytic activity of these strains has been
reported.
