Identification And Characterization

Bananas are important crops in developing countries with tropical climate. In Mexico, the banana production has increased, and it must be guaranteed. The Panama disease, caused by the fungus Fusarium oxysporum f.sp. cubense threatens the current banana production, for what is necessary to implement methods to protect this crop. Fungi from genus Trichoderma are natural residents of the rhizosphere. This genus comprises mycoparasite species used to control diseases caused by phytopathogenic fungi, and also benefit plant development. In this report, we present data of the identification and characterization of the novel strain Trichoderma harzianum M110 that displays antagonism and biocontrol potential in laboratory conditions. Exploration of the rhizosphere and the endophytic microbial communities might help to identify microbes adapted to banana plants that can be incorporated in organic biological control formulations that ensure production of Fusarium-free plants and healthy fruits with export quality.

Inhibitor Analysis

The presence of protein in the culture medium induced secretion of proteases in the studied filamentous fungi species. Comparative analysis of extracellular proteases expressed in vivo by saprotrophic (Trichoderma harzianum, Penicillium terlikowskii) and pathogenic (Alternaria alternata, Botrytis cinerea, Ulocladium botrytis) filamentous fungi species has been carried out. All isolated enzymes were classified as serine proteases on the basis of inhibitor analysis data. According to substrate specificity and the effect of some inhibitors it is proposed that enzymes from T. harzianum and P. terlikowskii are subtilisin-like proteases and enzymes from A. alternata, B. cinerea, U. botrytis are trypsin-like proteases. This fact is, apparently, one of the main characteristic properties of saprophytic and phytopathogenic fungi species. Participation of extracellular fungal proteases in pathogenesis is discussed.

Mycoparasitic Fungus

Trichoderma harzianum is a well-known mycoparasitic fungus that has been used as biocontrol agent of many phytopathogenic fungi. One of the effort to improve the ability of wild strain of T. harzianum in its antagonistic activity is by exposed them in gamma ray iradiation. In this experiment wild strain of T. harzianum iradiated gamma ray of Cobalt-60 (0.25 kGy, 0.5 kGy, 0.75 kGy, and 1 kGy), then assess the effect of the iradiation on its growth, the antagonistic activity and chitinase activity toward Fusarium oxysporum. Results showed that iradiation of gamma ray 0.25–1 kGy has no effect on the growth of T. harzianum and its antagonistic activity, but it significantly influence the chitinase activity. Probably the fungi have repaired the damage of DNA caused by iradiation, so that the growth and even the enzymatic function has no longer affected.
