Abstract(s)

Trichoderma has been related to the mycoparasitism process due to an extraordinary range of cell-wall degrading enzymes (CWDE): chitinases, β-1,3 and β-1,6 glucanases, celulases and proteases. However, the role of lipases and carboxylesterases in this process is less known, although lipids were up to 3% of fungal CW (Feofilova, 2010). According to Silva et al. (2009) and Lopes et al. (2012), in experiments involving T. reesei and Pythium ultimum, it seems that lipases are implicated in mycoparasitism and are secreted in a phytopathogen-dependent manner, as they, like most of the CWDE already described, are inducible by substrate. One of the purposes of this work was to find if the lipolytic enzymes of T. harzianum were alike homologous enzymes of other Trichoderma species. Here we present our contribution to the knowledge of T. harzianum T34 lipolytic enzymes (EC 3.1.1).
