Transcriptional regulation of the Trichoderma longibrachiatum egl1 gene

Transformants of Trichoderma longibrachiatum Overexpressing the beta-1,4-Endoglucanase Gene egl1 Show Enhanced Biocontrol of Pythium ultimum on Cucumber.

ABSTRACT Nine transformants of Trichoderma longibrachiatum with extra copies of the egl1 gene were studied for mitotic stability, endoglucanase production, and biocontrol activity against Pythium ultimum on cucumber seedlings. The transformants showed a significantly higher level of expression of the egl1 gene in comparison to the wild type under both inducing and noninducing growth conditions....

Nucleotide sequence of a Trichoderma longibrachiatum DNA fragment encoding the 5.8S rRNA gene.

Trichoderma longibrachiatum IMI061758 possesses a powerful cellulose enzyme complex composed by different cellobiohydrolase, endoglucanase and /3-glucosidase activities. Recently we have cloned the T. longibrachiatum egll gene encoding a /S-{l,4)-endoglucanase activity (1). From an industrial point of view, we are interested in the design of strains which have an increased egll gene dosage. To ...

Development of permeable reactive biobarrier for the removal of PAHs by Trichoderma longibrachiatum.

In this work, the formation of permeable reactive biobarriers (PRBBs) using Trichoderma longibrachiatum over nylon sponge as bioreactive medium for removal of polycyclic aromatic hydrocarbons (PAHs) was studied. Colony formation was pretested without PAH presence by inoculation of fungus into nylon sponge. The fungus formed a large quantity of strongly adhesive biofilm among nylon sponge. After...

Molecular phylogeny and species delimitation in the section Longibrachiatum of Trichoderma

The phylogenetically most derived group of the genus Trichoderma - section Longibrachiatum, includes some of the most intensively studied species, such as the industrial cellulase producer T. reesei (teleomorph Hypocrea jecorina), or the facultative opportunistic human pathogens T. longibrachiatum and H. orientalis. At the same time, the phylogeny of this clade is only poorly understood. Here w...
