title: Trichothecenes produced by Stachybotrys atra from Eastern Europe.
abstract: A total of 17 isolates of Stachybotrys atra isolated from various parts of Hungary and Czechoslovakia were grown on rice, and the toxin production of each isolate was analyzed by high-performance liquid chromatography. Of the 17 isolates, 14 produced macrocyclic trichothecenes (satratoxins F, G, and H, roridin E, and verrucarin J) as well as trichoverrols A and B. Most isolates produced satratoxins G and H in higher quantities than the other trichothecenes. The yield (in milligrams) of trichothecenes produced by one isolate grown on 800 g of rice was as follows: roridin E, 12; satratoxin F, 10; satratoxin G, 75; satratoxin H, 100; trichoverrol A, 15; and trichoverrol B, 30.
