Abstract

In this study, minerals required for the growth and aflatoxin production of A. flavus were determined. Then, the effectiveness of some chelating agents such as citric acid, phytic acid and ethylenediaminetetraacetic acid (EDTA) in preventing mold growth and toxin production was investigated in a fig-based medium and in two synthetic media, called Czapek-dox agar (CZA) and potato dextrose agar (PDA). A. flavus did not grow in CZA without sodium nitrate during 6-day incubation at 30 °C. The absence of the other components (magnesium sulfate, iron sulfate, potassium chloride and potassium phosphate) did not significantly (p>0.05) affect the growth of the mold. However, the mold produced significantly (p

Özet

Bu çalışmada, A. flavus küfünün gelişmesi ve aflatoksin üretmesi içinihtiyaç duyduğu mineral maddeler tespit edilmiştir. Daha sonra, sitrikasit, fitik asit, etilendiamintetraasetik asit (EDTA) gibi bazı şelatajanlarının; incir-bazlı bir ortam, Czapek-dox agar (CZA) ve patatesdekstroz agar (PDA) besiyerlerinde küfün gelişmesi ve toksin üretmesiniönlemedeki etkinliği araştırılmıştır. Sodyum nitrat içermeyen CZAbesiyerinde 30 °C’deki 6 günlük inkübasyon süresince A. flavus küfününhiç gelişmediği saptanmıştır. Diğer bileşenlerin (magnezyum sülfat,demir sülfat, potasyum klorür ve potasyum fosfatın) besiyerindebulunmaması, küfün gelişimini istatistiksel olarak anlamlı bir şekildeetkilememiştir (p>0.05). Ancak magnezyum sülfat ve demir sülfatiçermeyen besiyerlerinde istatistiksel olarak anlamlı düzeyde yüksekmiktarlarda aflatoksin üretimi gözlenmiştir (p
