Survey and control of the occurrence of mycotoxins from postharvest cereals. 1. Mycotoxins produced by Penicillium isolates from corn and wheat.

A total of 26 and 55 fungal isolates were collected from maize and wheat samples, respectively, from different markets in the Korea Republic. The number of Penicillium isolates were 9 from maize and 33 from wheat. The Penicillium species isolated from maize were P. chrysogenum (3 isolates) and P. oxalicum (6 isolates), and from wheat were P. aurantiogriseum (16 isolates), P. citrinum (1 isolate), P. commun (4 isolates), P. griseofulvum (1 isolate), P. verrucosum (7 isolates) and P. viridicatum (4 isolates). The production of major mycotoxins in the yeast extract sucrose medium cultures of Penicillium isolates was analysed. Penicillium cultures were extracted with chloroform and purified by TLC and HPLC. Of 9 isolates of Penicillium from maize, 2 isolates of P. chrysogenum produced patulin, 1 isolate produced patulin and citrinin, 2 isolates of P. oxalicum produced penicillic acid and 4 isolates produced penicillic acid and griseofulvin. Of the 33 isolates of Penicillium from wheat, 6 isolates of

 P. aurantiogriseum produced patulin, 8 isolates produced penicillic acid, 1 isolate produced patulin and penicillic acid, 1 isolate of P. citrinum produced citrinin and patulin, 2 isolates of P. commun produced brefeldin A and patulin, 1 isolate of P. griseofulvum produced brefeldin A, griseofulvin and patulin. Five isolates of P. verrucosum produced patulin, 1 isolate produced penicillic acid, and 3 isolates of P. viridicatum produced penicillic acid.
