ABSTRACT
Trichoderma (teleomorph Hypocrea, Hypocreales, Ascomycota, Dikarya) species are among the most common mitosporic fungi recovered in cultivation-based surveys of soil samples. They have also been isolated from an innumerable diversity of natural and articial substrata, thus illustrating a high opportunistic potential and adaptability to various ecological conditions [1,2]. Some are applied in biotechnology due to their abilities to (1) produce enzymes such as cellulases and hemicellulases for conversion of plant biomass into soluble sugars used for biorenery processes [3,4], (2) combat phytopathogenic fungi [5] and nematodes [6,7], and (3) stimulate plant defenses against plant pathogens [2,5]. Thus they are of considerable importance to mankind.
