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 کاملFusarium tricinctum T-2 Toxin Inhibits Auxin-promoted Elongation in Soybean Hypocotyl.
T-2 toxin, a mycotoxin produced by Fusarium tricinctum, inhibited elongation of excised hypocotyl sections of Glycine max var. Hawkeye 63. Auxin-promoted elongation was inhibited more severely than was control elongation, and a 1 hour preincubation of 5 mum toxin prevented the induction of a faster rate of elongation by auxin. While the inhibition of elongation by cytokinin was similar to that ...
متن کاملOptimization of enniatin production by solid-phase fermentation of Fusarium tricinctum.
Enniatins are cyclic depsipeptides produced by fungi of the genus Fusarium that are of interest due to their pronounced biological activities; especially enniatins A, A1, B, and B1 possess anticarcinogenic and anti-HIV properties. In the present study, F. tricinctum was grown on seven solid media and in one liquid growth medium with or without addition of peptone or of amino acid precursors in ...
متن کاملBiological assays for two mycotoxins produced by Fusarium tricinctum.
A survey was made to detect microorganisms useful for assaying butenolide [4-acetamido-4-hydroxy-2-butenoic acid gamma-lactone] and T-2 toxin [4beta, 15-diacetoxy-8alpha-(3-methylbutyryloxy)-12,13-epoxytricothec -9-en-3alpha-ol]. These mycotoxins produced by strains of Fusarium tricinctum have been implicated in mycotoxicosis of livestock. Although butenolide proved to be a very weak antibiotic...
