Abstract
|
|
|
These studies were carried out to detect the presence of mycotoxin producing fungi and detoxification of toxins in various kinds of poultry feedstuffs in Korea.
The experimental were divided into two parts: first the mycologic and second the toxicologic study.
The results of experiment were summarized as follows:
From the 54 various samples, 349 strains of fungi were isolated. In 336 of 349 strains, there were possible to identify in 8 genera. Among the identified strains, the predominant genera were Penicillium sp.(24.9%), Aspergillus sp.(22.9%) and Alternaria sp.(20.6%).
In cytotoxicity test in Hela cells, 12 strains showed toxic effect among the 16 strains which were producing toxin-like substances.
In the detoxification study with ultraviolet irradiation, all of the experimental toxic substances were denatured by the ultraviolet irradiation of 24 hours.
