In this study, a transgenic strain of Trichoderma atroviride was characterized. The transgenic strain contains an endochitinase gene (ThEn-42) driven by the cellulase promoter cbh1 of T. reesei for overexpression of ThEn-42. The culture filtrates of the transformant and the parental strain grown in eight different media were evaluated for chitinase and antifungal enzyme production based on activity gels, protein profiles, and antifungal activities. Results demonstrated that chitinases are important components and synergistic interactions play a key role in the antagonistic action of T. atroviride. Moreover, altering medium nutrient concentration and composition led to enhanced production of antifungal enzymes, a potential strategy for mass production. Two of the culture filtrates contained almost pure endochitinase, and could be excellent commercial sources for this enzyme. Several culture filtrates were highly antifungal. Two filtrates were so effective in biocontrol of a fungal pathogen, Penicillium digitatum, that they not only inhibited spore germination but destroyed the spores completely when 20 \u00B5l of culture filtrate (corresponding to approximately 104 \u00B5g of total protein) was applied in a total volume of 150 \u00B5l (approximately 0.7 mg protein ml-1)." ; prodottidellaricerca:prodottoDi istituto:CDS064 , modulo:ID5881 ; pubblicazioni:autoreCNR unitaDiPersonaleEsterno:ID6644 . @prefix parolechiave: . prodotto:ID41130 parolechiave:insiemeDiParoleChiave . ns11:ID426985 pubblicazioni:rivistaDi prodotto:ID41130 . parolechiave:insiemeDiParoleChiaveDi prodotto:ID41130 .
