HOLGUIN CASTANO, VILMA AMPARO  y  MORA-DELGADO, JAIRO. MICROBIAL DYNAMICS IN COMMERCIAL VERMICOMPOSTS WITH AND WITHOUT TRICHODERMA SPP. FUNGUS INOCULATION. Luna Azul [online]. 2009, n.29, pp.18-24. ISSN 1909-2474.

In tThis paper, presents the results are presented onof the growthefectiveness of the Trichoderma fungus in a inoculation in a commercial vermicompost, in comparison with the fungus from a vermicompostand without inoculation. In a three-phase laboratory process (cultivation, isolation and inoculation of fungal strains), three different commercial vermicompost, prepared from coffee pulp, have beenwere used, coming from three different commercial vermicomposts. The results of experiments carried out in the Post-Harvest Laboratory of the Universidad de Costa Rica, don’t show any increase or decrease of the Trichoderma population after inoculation. The experiment was carried out in the Post -harvest Laboratory of University of Costa Rica. It was developed following three phases, using three commercial vermicompost prepared with broza of coffee. Results showed no differences in Trichoderma population as product of inoculation of it into the compost.
