Trichoderma reesei is a biotechnically important filamentous fungus used commercially in enzyme production. T. reesei is also one of the best known cellulolytic organisms, producing readily and in large quantities a complete set of extracellular cellulases for the degradation of crystalline cellulose. In addition to T. reesei, a wide variety of other bacteria and fungi also produce cellulolytic...

Different mixed cultures of Trichoderma reesei and a yeast were cultivated on beet pulp (BP)-containing medium. T. reesei and Kluyveromyces marxianus offered a combination that gave high SCP yields (51%) and efficiently converted BP into proteins (39.4%). The yeast extract in the basal medium could be substituted and the BP level multiplicated from 2 to 4% upon using mixed culture of T. reesei ...

BACKGROUND Trichoderma reesei, a mitosporic green mould, was recognized during the WW II based on a single isolate from the Solomon Islands and since then used in industry for production of cellulases. It is believed to be an anamorph (asexual stage) of the common pantropical ascomycete Hypocrea jecorina. METHODOLOGY/PRINCIPAL FINDINGS We combined molecular evolutionary analysis and multiple ...

Two genes involved in protein secretion, encoding the Rab protein YPT1/YPTA and the general fusion factor NSFI/NSFA, were characterized from two filamentous fungi, Trichoderma reesei and Aspergillus niger var. awamori. The isolated genes showed a high level of conservation with their Saccharomyces cerevisiae and mammalian counterparts, and T. reesei ypt1 was shown to complement yeast Ypt1p depl...

This study aimed to explore the effects of Trichoderma reesei FS10-C on the phytoremediation of Cd-contaminated soil by the hyperaccumulator Sedum plumbizincicola and on soil fertility. The Cd tolerance of T. reesei FS10-C was characterized and then a pot experiment was conducted to investigate the growth and Cd uptake of S. plumbizincicola with the addition of inoculation agents in the presenc...

Sexual development is regulated by a complex regulatory mechanism in fungi. For Trichoderma reesei, the light response pathway was shown to impact sexual development, particularly through the photoreceptor ENVOY. Moreover, T. reesei communicates chemically with a potential mating partner in its vicinity, a response which is mediated by the velvet family protein VEL1 and its impact on secondary ...

The mesophilic filamentous fungus Trichoderma reesei (teleomorph Hypocrea jecorina) has become a major cell factory in the enzyme industry, and the benchmark organism for production of cellulases, especially for biomass conversion. The strain was originally isolated during the second World War from US Army tent canvas in the Solomon Islands and initially identified as Trichoderma viride. The is...

BACKGROUND Trichoderma reesei is a widely used industrial strain for cellulase production, but its low yield of β-glucosidase has prevented its industrial value. In the hydrolysis process of cellulolytic residues by T. reesei, a disaccharide known as cellobiose is produced and accumulates, which inhibits further cellulases production. This problem can be solved by adding β-glucosidase, which hy...

Cellulase production was evaluated in two reference strains (T. reesei Rut-C30 and T. reesei QM9414), two strains isolated from a sugarcane cultivation area (Trichoderma sp. IPT778 and T. harzianum rifai IPT821) and one strain isolated in a program for biodiversity preservation in São Paulo state (Myceliophthora thermophila M77). Solid state cultures were performed using sugarcane bagasse (C), ...

The putative methyltransferase LaeA is a global regulator that affects the expression of multiple secondary metabolite gene clusters in several fungi, and it can modify heterochromatin structure in Aspergillus nidulans. We have recently shown that the LaeA ortholog of Trichoderma reesei (LAE1), a fungus that is an industrial producer of cellulase and hemicellulase enzymes, regulates the express...
