Aspergillus niger van Tieghem, Aspergillus tamarii Kita, and Aspergillus flavus Link ex Fries utilized the methylthio moiety of 2,4-bis(isopropylamino) -6-methyl-mercapto-s-triazine (prometryne) as a sulfur nutrient source. Other soil fungal isolates not affected by prometryne concentrations to 1 mg/ml culture included: Aspergillus oryzae (Ahlburg) Cohn, Curvularia lunata (Wakker) Boedijn, Tric...

The present study explored the neuroprotective effect of Coeloglossum viride var. bracteatum extract (CE) against oxidative stress in rat cortical neurons. The results demonstrated that administration of CE inhibited hydrogen peroxide-induced neurotoxicity tested by MTT, LDH release, and TUNEL assays. We further found that CE inhibited the activation of caspase-3 (Csp3) induced by hydrogen pero...

The use of Trichoderma isolates with efficient antagonistic activity represents a potentially effective and alternative disease management strategy to replace health hazardous chemical control. In this context, twenty isolates were obtained from tomato rhizosphere and evaluated by their antagonistic activity against four fungal pathogens (Fusarium oxysporum f. sp. lycopersici, Alternaria altern...

Trichoderma spp. are fungi that occur worldwide. Recent studies show that they are not only parasites of fungal plant pathogens but also can produce antibiotics. In addition, certain strains can induce systemic and localized resistance to several plant pathogens. Moreover, some strains may enhance plant growth and development. The potential of Trichoderma species used as biological agents of pl...

2-Methyl-8-quinolinol and sixteen 5-, 7-, and 5,7-substituted derivatives with fluoro, chloro, bromo, iodo, nitro, and amino substituents were tested for in vitro antifungal activity against five fungi, Aspergillus niger, A. oryzae, Trichoderma viride, Myrothecium verrucaria, and Trichophyton mentagrophytes. The 5,7-dichloro and 5,7-dibromo derivatives were the most fungitoxic of the compounds ...

Aspergillus parasiticus RCMB 002001 (2) producing four types of aflatoxins B1, B2, G1, and G2 was used in this study as an aflatoxin-producer. Penicillium griseofulvum, P. urticae, Paecilomyces lilacinus, Trichoderma viride, Candida utilis, Saccharomyces cerevisiae as well as a non-toxigenic strain of Aspergillus flavus were found to be able to exhibit growth on aflatoxin B1-containing medium u...

Among the single treatments tested under in vivo addition of well decomposed FYM 20 tons per hectare as soil amendment recorded minimum wilt incidence of 3.75, 24.76 and 48.25 % at flowering, fruit formation and ripening stages of chilli crop, respectively, with 61.31 q ha fruit yield as compared to check (42.50 q ha). Dual application of Trichoderma viride 0.16 t ha + FYM 20 t ha recorded mini...

The aim of the study was to assess the cellulolytic activity of a strain of Trichoderma viride in the presence of three lignocellulosic substrates, i.e. wheat, barley, and maize straw, in different temperatures (25 °C, 30 °C and 35 °C). Research related to the biosynthesis of enzymes was conducted using the deep method, whereas enzyme activity was assessed on solid media with added carboxymethy...

Ability of Cr (VI) biosorption with immobilized Trichoderma viride biomass and cell free Ca-alginate beads was studied in the present study. Biosorption efficiency in the powdered fungal biomass entrapped in polymeric matric of calcium alginate compared with cell free calcium alginate beads. Effect of pH, initial metal ion concentration, time and biomass dose on the Cr (VI) removal by immobiliz...

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...
