T-2 toxin production by Fusarium tricinctum on solid substrate.
A method has been developed to produce and purify gram quantities of T-2 toxin [4beta, 15-diacetoxy-8alpha-(3-methylbutyryloxy)-12, 13-epoxytrichothec-9-en-3alpha-ol], a mycotoxin elaborated by a strain of Fusarium tricinctum isolated from toxic corn. After growing for 3 weeks at 15 C on 1,200 g of white corn grits, F. tricinctum NRRL 3299 elaborated at least 9.0 g of T-2 toxin, and 2.3 g of cr...
متن کاملBiosynthesis of radiolabeled T-2 toxin by Fusarium tricinctum.
Incubation of Fusarium tricinctum NRRL 3299 on a solid rice medium in the presence of [1-14C]sodium acetate, [2-3H]mevalonic acid, [2-14C]mevalonic acid, or [5-3H]mevalonic acid yielded preparations of radiolabeled T-2 toxin with specific activities of 1.008, 1.64, 0.656, and 7.35 muCi/mmol, respectively.
متن کاملMetabolism of HT-2 Toxin and T-2 Toxin in Oats
The Fusarium mycotoxins HT-2 toxin (HT2) and T-2 toxin (T2) are frequent contaminants in oats. These toxins, but also their plant metabolites, may contribute to toxicological effects. This work describes the use of 13C-assisted liquid chromatography-high-resolution mass spectrometry for the first comprehensive study on the biotransformation of HT2 and T2 in oats. Using this approach, 16 HT2 and...
متن کاملPhylogenetic analyses and toxigenic profiles of Fusarium equiseti and Fusarium acuminatum isolated from cereals from Southern Europe.
Fusarium equiseti and Fusarium acuminatum are toxigenic species that contaminate cereal crops from diverse climatic regions. They are common in Spanish cereals. The information available on their phylogenetics and toxigenic profiles is, however, insufficient to assist risk evaluation. In this work, phylogenetic analyses were performed using partial sequences of the translation elongation factor...
متن کاملMycotoxin production by Fusarium oxysporum and Fusarium sporotrichioides isolated from Baccharis spp. from Brazil.
Fusarium oxysporum isolated from roots of and soil around Baccharis species from Brazil produced the trichothecenes T-2 toxin, HT-2 toxin, diacetoxyscirpenol, and 3'-OH T-2 (TC-1), whereas Fusarium sporotrichioides from the same source produced T-2 toxin, HT-2 toxin, acetyl T-2, neosolaniol, TC-1, 3'-OH HT-2 (TC-3), iso-T-2, T-2 triol, T-2 tetraol, and the nontrichothecenes moniliformin and fus...
