TL;DR: SEM and TEM micrographs show that the mycoparasite degraded walls of sclerotial cells and the attacked cells lost their cytoplasmic contents, and it is assumed that T. harzianum utilizes sclerOTial cell contents thus enabling it to sporulate intensively on the sclerotsial surface and inside the digested cells.
Abstract: The ability of Trichoderma harzianum isolate 203 to attack the soil-borne plant pathogen Sclerotium rolfsii is apparently connected with the production by the isolates of chitinase and β-(1,3)-glucanase inside the attacked sclerotia during parasitism. SEM and TEM micrographs show that the mycoparasite degraded walls of sclerotial cells and the attacked cells lost their cytoplasmic contents. It is assumed that T. harzianum utilizes sclerotial cell contents thus enabling it to sporulate intensively on the sclerotial surface and inside the digested cells.

TL;DR: In this paper, the authors evaluated the interactions between four AMF (Glomus intraradices, Glomus mosseae, glomus claroideum, and Glus constrictum) and Trichodermaharzianum for their effects on melon plant growth and biocontrol of Fusarium wilt in seedling nurseries.
Abstract: BACKGROUND: Biological control through the use ofTrichoderma spp. and arbuscular mycorrhizal fungi (AMF) could contribute to a reduction of the inputs of environmentally damaging agrochemical products. The objective of this study was to evaluate the interactions between four AMF (Glomus intraradices, Glomus mosseae, Glomus claroideum and Glomus constrictum )a nd Trichodermaharzianum for their effects on melon plant growth and biocontrol of Fusarium wilt in seedling nurseries. RESULTS: AMF colonisation decreased fresh plant weight, which was unaffected by the presence of T. harzianum. Dual inoculation resulted in a decrease in fresh weight compared with AMF-inoculated plants, except for G. intraradices .A MF colonisation level varied with the AM endophyte and was increased by T. harzianum ,e xcept inG. mosseae-inoculated plants. Negative effects of AMF on T. harzianum colony-forming units were found, except with G. intraradices. AMF alone were less effective than T.harzianum in suppressing disease development. Combined inoculation resulted in a general synergistic effect on disease control. CONCLUSION: Selection of the appropriate AMF species and its combination with T. harzianum were significant both in the formation and effectiveness of AM symbiosis and the reduction of Fusarium wilt incidence in melon plants. The combination of G.intraradices andT.harzianum provided better results than any other tested. c � 2009 Society of Chemical Industry

TL;DR: In this paper, the growth of several agriculturally and industrially important fungi on cranberry pomace substrate through solid-state fermentation was investigated. And the authors concluded that bioconversion of cranberry processing waste by industrial beneficial fungi through solid state fermentation was feasible.

TL;DR: When the mycoparasitic, biocontrol fungus Trichoderma harzianum was allowed to grow on nylon fibers treated with concanavalin A or Sclerotium rolfsii lectin, it coiled around the nylon fibers and produced hooks in a pattern similar to that observed with the real host hyphae.
Abstract: When the mycoparasitic, biocontrol fungus Trichoderma harzianum was allowed to grow on nylon fibers treated with concanavalin A or Sclerotium rolfsii lectin, it coiled around the nylon fibers and produced hooks in a pattern similar to that observed with the real host hyphae. The incidence of interaction between T. harzianum and S. rolfsii lectin-treated fibers was significantly higher than that of the controls (untreated or blocked activated fibers). These findings provide direct evidence for the role of lectins in mycoparasitism.

TL;DR: In vitro assays indicated that Pe-AFP1 was able of inhibiting the development of the filamentous fungi Trichoderma harzianum, Fusarium oxysporum, and Aspergillus fumigatus, but not of Rhyzoctonia solani, Paracoccidioides brasiliensis and Candida albicans.
