TL;DR: The study demonstrated a significant effect of xylanases from T. longibrachiatum, the presence of which evoked a 27-45% increase in the effectiveness of polysaccharides hydrolysis compared to the enzymatic complexes without their addition.

TL;DR: In this article, three different Trichoderma species (T. harzianum, T. viride, and T. longibrachiatum) were examined on five different culture media includings Potato Dextrose Agar, Waksman agar, Agar-agar, Czepak's agar and Corn Meal agar.
Abstract: Mycelial growth, conidal production and biomass yield of three different Trichoderma species (T. harzianum, T. viride, T. longibrachiatum) were examined on five different culture media includings Potato Dextrose Agar, Waksman agar, Agar-agar, Czepak’s agar and Corn Meal agar. The medium had a significant effect on growth rate and population of the three Trichoderma species. Potato Dextrose Agar was the best medium in terms of growth spore production and biomass yield. Trichoderma harzianum outclassed the three in terms of mycelial growth biomass yield and spore production. In-vitro, species of Trichoderma strongly antagonised six different seed borne pathogenic fungi viz. Fusarium moniliforme, Fusarium oxysporum, Rhizoctonia solani, Fusarium solani, Botryodiplodia theobromae and Alternaria alternata in dual culture assay. Trichoderma harzianum gave maximum inhibition of mycelia growth of all pathogenic fungi.

TL;DR: Six long‐chain peptaibols, 1 – 6, were identified from agar cultures of a marine‐derived Trichoderma longibrachiatum Rifai strain isolated from blue mussels, and three new sequences were identified and were calledLongibrachins A‐0, A‐II‐a, and A‐IV‐b.
Abstract: Six long-chain peptaibols, 1 - 6, were identified from agar cultures of a marine-derived Trichoderma longibrachiatum Rifai strain (MMS151) isolated from blue mussels. The structure elucidation was carried out using electrospray ionization ion trap mass spectrometry (ESI-IT-MS) and GC/EI-MS. The long-chain peptaibols exhibited the general building scheme Ac-Aib-Ala-Aib-Ala-Aib-XXX-Gln-Aib-Vxx-Aib-Gly-XXX-Aib-Pro-Vxx-Aib-XXX-Gln-Gln-Pheol and were similar or identical to recurrent 20-residue peptaibols produced by Trichoderma spp. Three new sequences were identified and were called longibrachins A-0, A-II-a, and A-IV-b. The isolated peptaibols were assayed for cytotoxic, antibacterial, and antifungal activities, and acute toxicity on Dipteran larvae.

TL;DR: A well-documented case of otitis externa due to Trichoderma longibrachiatum is reported, confirmed by direct sequencing of a fragment coding for the ribosomal DNA, to illustrate the wide spectrum of fungal pathogens isolated in otomycosis.
Abstract: Fungi are occasional pathogens in otitis externa, mainly in chronic infections [1]. Aspergillus spp., the main pathogens of otomycosis, are responsible for 54–80% of cases [2, 3]. We report here a well-documented case of otitis externa due to Trichoderma longibrachiatum. The identification was confirmed by direct sequencing of a fragment coding for the ribosomal DNA. This case and other reports in the literature illustrate the wide spectrum of fungal pathogens isolated in otomycosis and the growing importance of molecular biology in the field of identification in medical mycology.
