Trichothecenes produced by Stachybotrys atra from Eastern Europe
Applied and Environmental Microbiology
|May 1, 1986
Summary
Seventeen Stachybotrys atra isolates were analyzed for toxin production. Most isolates produced macrocyclic trichothecenes, with satratoxins G and H being the most abundant toxins.
Area of Science:
- Mycology
- Environmental Science
- Toxicology
Background:
- Stachybotrys atra is a fungus known for producing mycotoxins.
- Understanding the toxin profiles of different isolates is crucial for risk assessment.
Purpose of the Study:
- To analyze the toxin production of Stachybotrys atra isolates from Hungary and Czechoslovakia.
- To identify and quantify the specific mycotoxins produced by these isolates.
Main Methods:
- Seventeen Stachybotrys atra isolates were cultured on rice.
- Toxin production was analyzed using high-performance liquid chromatography (HPLC).
Main Results:
- Fourteen out of 17 isolates produced macrocyclic trichothecenes (satratoxins F, G, H; roridin E; verrucarin J) and trichoverrols A and B.
- Satratoxins G and H were the most frequently produced toxins in higher quantities.
- Specific yields were quantified, e.g., satratoxin H (100 mg) and satratoxin G (75 mg) per isolate.
Conclusions:
- Stachybotrys atra isolates from the studied regions commonly produce a range of potent mycotoxins.
- The dominance of satratoxins G and H in production highlights their significance in the toxicological profile of these isolates.
