The effect of zinc and phytic acid on the incorporation of 1-14C-acetate into aflatoxin by resting mycelia of Aspergillus parasiticus
Description
The effect of zinc and phytic acid on [1-14C]-acetate incorporation into aflatoxins by resting mycelium was studied. When different levels of ZnSO4 were used to study its effect on the incorporation of [1-14C]-acetate into aflatoxins, it was found that the specific radioactivity incorporation into aflatoxins was maximum at the level of 10 mM-ZnSO4. At this concentration the change in the specific radioactivities of aflatoxins B1 + B2 and aflatoxins G1 + G2 were +74.61% and +29.66%, respectively. On the other hand, phytic acid had an inhibitory effect on the incorporation of [1-14C]-acetate. These observations have been correlated in order to find out why soyabean is unable to produce aflatoxins by Aspergillus parasiticus. (orig.)
Abstract (German)
Die Wirkung des Zinks und der Phytinsaeure auf den Einbau von 1-14C-Acetat in Aflatoxine durch ruhendes Mycel wurde studiert. Wenn verschiedene Mengen von ZnSO4 angewendet wurden, um deren Einfluss auf den Einbau von 1-14C-Acetat in Aflatoxine zu studieren, so wurde gefunden, dass die spezifische Radioaktivitaet bei einem Maximum von 10 mmol-ZnSO4 lag. Bei diesen Konzentrationen waren die Verbindungen in der spezifischen Radioaktivitaet der Aflatoxine B1 und B2 bzw. G1 und G2 74,61 bzw. 29,66%. Andererseits hatte die Phytinsaeure einen hemmenden Einfluss auf den Einbau von 1-14C-Acetat. Diese Beobachtungen stimmen mit der Tatsache ueberein, dass Aspergillus parasiticus auf Sojabohnen als Naehrboden unfaehig ist, Aflatoxine zu produzieren. (orig.)Additional details
