چکیده
Crude extracts of filtrates of cultures of Fusarium sambucinum NRRL 13495 were acetylated or hydrolyzed. After chromatography on cartridge columns of silica gel and recrystallization three times from mixtures of ethyl acetate and hexane, 3,4,15-triacetoxyscirpenol (435 +/- 10 mg/liter of filtrate; mean +/- standard error [n = 3]) and the parent alcohol scirpentriol were isolated (261 +/- 29 mg/liter of filtrate; mean +/- standard error [n = 3]) in 68 and 53% yield for a 130- and 14-fold improvement, respectively, over prior reports.

Preparation of 4,15-diacetoxyscirpenol from cultures of Fusarium sambucinum NRRL 13495.
Filtrates of Fusarium sambucinum NRRL 13495 grown in a stagnant culture for 9 days contained up to 458 +/- 60 (mean +/- standard error; n = 3) mg of 4,15-diacetoxyscirpenol per liter depending on culture conditions. Extraction with ethyl acetate, chromatography on a column of silica gel, and crystallization from mixtures of ethyl acetate and hexane provided pure material in 96% yield.
متن کاملRegulation of Trichodiene Synthase in Fusarium sporotrichioides and Gibberella pulicaris (Fusarium sambucinum).
The regulation of trichodiene synthase (TS) and its relationship to trichothecene biosynthesis was investigated in Fusarium sporotrichioides NRRL 3299 and Gibberella pulicaris R-6380. Cultures were analyzed for the presence of TS activity, trichothecenes, and immunodetectable TS polypeptide over a time period of 144 h. Enzyme activity increased from barely detectable to maximum levels over a pe...
متن کاملThe arbuscular mycorrhizal fungus, Glomus irregulare, controls the mycotoxin production of Fusarium sambucinum in the pathogenesis of potato.
Trichothecenes are an important family of mycotoxins produced by several species of the genus Fusarium. These fungi cause serious disease on infected plants and postharvest storage of crops, and the toxins can cause health problems for humans and animals. Unfortunately, there are few methods for controlling mycotoxin production by fungal pathogens, and most rely on chemicals, creating therefore...
متن کاملProduction of volatile sesquiterpenes by Fusarium sambucinum strains with different abilities to synthesize trichothecenes.
Twenty-five strains of Fusarium sambucinum grown on wheat kernels were examined for trichothecene production and the synthesis of volatile sesquiterpenes. The volatiles were purged with air and collected on Tenax traps. Adsorbed compounds were eluted from the traps and injected into a gas chromatograph coupled with a mass spectrometer. Ten strains isolated from potato tubers produced high amoun...
متن کاملSolid Phase Microbial Fermentation of Anabolic Steroid, Dihydrotestosterone with Ascomycete Fungus Fusarium Oxysporum
Objective: Microbial catalysis is used in the commercial production of many bioactive steroids. Solid phase microbial fermentation of anabolic steroid, dihydrotestosterone (DHT, 1), was carried out with ascomycete fungal strain Fusarium oxysporum (NRRL-1392). Methods: Sabouraud-4% glucose-agar was used to cultivate the fungal cultures as solid phase medium. Substrate 1 was incubated with Fusari...
