The count of cultivable microorganisms (bacteria and fungi), cellulolytic microorganisms and endomycorrhizas present in litter forest (property Puente de Tierra) in the Guerrero’s moor, Colombia was made. The most frequently isolated microorganisms belonged to the Staphylococcus, Bacillus, Pseudomonas, Micrococcus, Penicillium and Rhodotorula genus and Cladosporium sp., which is a cellulolytic microorganism, was isolated in carboxymethyl cellulose agar. In addition eight morphotypes of endomycorrhizas were found, species of Glomus and Acaulospora predominated among them. This study contributes with the knowledge of the cultivable microorganisms of litter that have been little explored in moor ecosystems.
