“…Strains have been exploited for production of enzymes and antibiotics, bioremediation of xenobiotic substances, and as biological control agents against plant pathogenic fungi and nematodes. Some species of Trichoderma can form intimate associations with plant roots, providing an endemic level of biological control or stimulating plant growth by producing soluble forms of mineral nutrients and growth-promoting metabolites (Altomare et al, 1999;Esposito and Da Silva, 1998;Katayama and Matsumura, 1993;Koenig et al, 1994;Sharon et al, 2001;Sivasithamparam and Ghissalberti, 1998;Yedidia et al, 2000).…”
