Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...

Root rot disease of Cuminum cyminum caused by Fusarium solani is one the most destructive diseases threatening cumin production. The present study investigates biocontrol potential some endophytes against F. and their effect on induction defense-related enzymes in a greenhouse. results herein presented illustrate strong three (out twelve) endophytes. During vitro assay, isolates demonstrated my...

O uso de fungos pertencentes ao gênero Trichoderma tem grande importância para a agricultura, promovendo crescimento vegetativo e radicular, assim como também o acréscimo clorofila da área foliar resultando no incremento produtivo. A melancieira, que é uma hortaliça-fruto relevância comércio brasileiro, bastante explorada em áreas semiáridas, com irregularidade chuvas escassez água boa qualidad...

A laminarinase [endo-(1,3)-beta-d-glucanase] has been purified from Trichoderma longibrachiatum cultivated with d-glucose as the growth substrate. The enzyme was found to hydrolyze laminarin to oligosaccharides varying in size from glucose to pentaose and to lesser amounts of larger oligosaccharides. The enzyme was unable to cleave laminaribiose but hydrolyzed triose to laminaribiose and glucos...

From the culture broth of the filamentous fungus Trichoderma parceramosum, strain CBS 936.69, a mixture of polypeptide antibiotics (pepaibiotics), named trichobrachin (TB), was isolated. Three major groups designated TB I, TB II, and TB III could be separated and isolated by preparative TLC on silica gel. Individual peptides of these three groups were sequenced by on-line LC/ESI-MS(n). The mixt...
