TL;DR: Results from non-volatile assay indicated that irrespective of concentration, culture filtrate of T. viride (TvL) was found to be most effective; recorded lowest radial growth and highest per cent inhibition followed by T. harzianum 14 (Th14) and T. longibrachiatum (Tl2).
Abstract: To evaluate the effect of Trichoderma spp. on radial growth of Sclerotium rolfsii, three species of Trichoderma viz., Trichoderma viride, Trichoderma harzianum and Trichoderma longibrachiatum were selected. The results from this experiment revealed that T. viride (TvL), T. harzianum 4 (Th 4) and T. harzianum 14 (Th14) isolates were found effective and showed lowest radial growth of 3.50 cm and highest per cent inhibition (56.25%) of S. rolfsii but were statistically on par with each other. The highest radial growth (4.23 cm) and lowest per cent inhibition (47.1%) were recorded with T. longibrachiatum (Tl2). Results from non-volatile assay indicated that irrespective of concentration, culture filtrate of T. viride (TvL) was found to be most effective; recorded lowest radial growth and highest per cent inhibition followed by T. harzianum 14 (Th14) and T. harzianum 4 (Th4).

TL;DR: It was shown that Trichoderma longibrachiatum was less competitive than Fusarium oxysporum after their simultaneous inoculation but inhibited the phytopathogen growth in the case of earlier introduction.
Abstract: The autoregulation of conidium germination in phytopathogenic micromycetes of the genera Fusarium, Botrytis, and Bipolaris was studied. It was shown that Trichoderma longibrachiatum was less competitive than Fusarium oxysporum after their simultaneous inoculation but inhibited the phytopathogen growth in the case of earlier introduction. In the latter case, no autoinhibition of the germination of F. oxysporum conidia occurred; moreover, a cooperative effect was observed, i.e., the number of germinated F. oxysporum conidia increased with an increase in their density.

TL;DR: The increased synthesis of lytic enzymes (proteases, β-1,3-glucanases) correlated with increased glucose concentration in the feeding medium and this effect potentiated at 34°C of cultivation.
Abstract: Continuous cultivation of Trichoderma reesei M-7 mutant was performed at different temperatures (26, 30 and 34°C) with 1% lactose or glucose alone or a total of 1% mixtures of both sugars at different ratio. The secretion of individual enzymes was affected by the ratio of cellulase inducer (lactose) to the repressor (glucose). The ratio of enzyme secretions was additionally modified by the temperature of cultivations. An insignificant increase of nonspecific activity of cellulases (FPU) and significant increase of aryl-β-glucosidase activity were observed at 26°C with lactose/glucose ratio of 3:1 and 1:1. However, when cultivated both at 30 or 32°C, the cellulolytic activities (FPU) increased significantly in the presence of 1% glucose alone. The activity of xylanases increased significantly (about 8-fold) with lactose/glucose ratio of 1:1 at 30°C. The increased synthesis of lytic enzymes (proteases, β-1,3-glucanases) correlated with increased glucose concentration in the feeding medium and this effect potentiated at 34°C of cultivation. Cette etude examine les facteurs affectant la composition des secretions d'un complexe enzymatique extracellulaire par un mutant Trichoderma reesei M-7. La secretion des enzymes individuelles est influencee par le taux de l'inducteur de la cellulase (lactose) sur le represseur (glucose). Le ratio des secretions enzymatiques est modifie en plus par la temperature des cultures.

TL;DR: In this article, a sugarcane filtered mud fermentation agent was described, which comprises bacillus subtilis, aspergillus oryzae, saccharomycetes and trichoderma longibrachiatum.
Abstract: The invention discloses a sugarcane filtered mud fermentation agent and a sugarcane filtered mud fermentation method. The sugarcane filtered mud fermentation agent comprises bacillus subtilis, aspergillus oryzae, saccharomycetes and trichoderma longibrachiatum, wherein the mass ratio of the bacillus subtilis, the aspergillus oryzae, the saccharomycetes and the trichoderma longibrachiatum is (14-16):(9-11):(4-6):(4-6). According to the sugarcane filtered mud fermentation agent, a plurality of strains are combined at a proper ratio, so that the temperature is raised quickly, the high-temperature time is long, the fermentation time is short and fermentation is conducted completely.

TL;DR: Observations showed that the properties of the investigated fungus are those which characterize other Trichoderma species as well.
Abstract: Physiological properties of the fungus Trichoderma longibrachiatum Rifai and its pathogenicity for maize seedling and young maize plants
In the 1977–1980 period Trichoderma longibrachiatum was found to make 1.7 % of the maize seed mycoflora in Slovenia/Yugoslavia. Its mycelium growth was investigated on complex as well as on defined substrates with regard to spore formation, light induction (which is indispensable for spore formation), temperature requirements, relative humidity and different C- and N-sources. These observations showed that the properties of the investigated fungus are those which characterize other Trichoderma species as well.
