Abstract

内容記述

[Synopsis] Barley is mainly produced in four provinces, Chonbuk, Chonnam, Kyungbuk, and Kyungnam, and corn is produced in the Kangwon province. The natural occurrence of Fusarium mycotoxins was surveyed during the last 10 years. Several trichothecenes and zearalenone were detected in cereals. Among these, deoxynivalenol (DON) and nivalenol (NIV) were the major trichothecenes in barley, whereas DON and 15-acetyl-DON were the major trichothecenes in corn. There was a remarkable difference in trichothecene production of F. graminearum isolates from barley compared to those from corn. The difference chemotypes in F. graminearum isolates from barley and corn supported that the natural occurrence of trichothcenes in the two cereals. There appears to be an uneven geographic distribution of NIV chemotypes in that the majorities are found in the southern provinces of Korea. During the screening of fumonisins produced by Fusarium species, one F oxysporum (MRC 7546) produced the C series of fumonisins as its major toxins. We obtained substantial amounts of the C series of fumonisins from wheat cultures of the isolate for chemical and toxicological studies. Fortyfour samples of visibly moldy corncobs were collected after harvest in the Kangwon province and surveyed the C series of fumonisins in moldy corn samples. Of the 44 moldy corn samples, 32 were contaminated with both the B and C series of fumonisins and 6 were contaminated with only B series of fumonisins. The level of the C series of fumonisins was approximately 10％ of those of the B series of fumonisins. A total of 104 F. moniliforme isolates were obtained from the moldy corn samples and examined for production of the B and C series of fumonisins. Among these isolates, 93 (82 ％) isolates produced both the B and C series of fumonisins. Most isolates of F. moniliforme produced the B series of fumonsins as their major toxins along with the C series of fumonisins as their minor components. Although the C series of fumonisins have not been tested as cancer initiators, they are potential carcinogens because the C series of fumonisins, like the B series, have a free amino group and their structures are similar to the B series of fumonisins except for the terminal methyl group.
