摘要

黄曲霉毒素（AF）和玉米赤霉烯酮（ZEN）是各种食品和饲料中最主要的真菌毒素。因此，本研究旨在评估酿酒酵母菌株的抗真菌活性，并研究它们在体外去除黄曲霉毒素B1（AFB1）和玉米赤霉烯酮（ZEN）的能力。数据显示，与酿酒酵母NRRL Y-1089相比，酿酒酵母NRLL Y-12633显示出更高的抗真菌活性。另一方面，酿酒酵母悬浮液表现出比酿酒酵母上清液更高的抗真菌活性。关于AFB1的去除，结果表明，在30分钟后，酿酒酵母NRRL Y-1089在5.0µg/mL的浓度下表现出更高的去除AFB1的能力，还原率达到87.20%，而酿酒酵母NRRLY-12633去除了21.00%。酿酒酵母NRRL Y-12633成功地去除了浓度为5.0µg/mL的ZEN 94.80%，而酿酒酵母NRRLY-1089去除了ZEN 91.80%。结果还表明，AFB1的去除率随着培养时间的增加而增加，而ZEN的去除率则随着培养时间的增加而降低。因此，酿酒酵母菌株可以作为添加剂降低食品和饲料中真菌毒素的浓度。

The Efficiency of Saccharomyces Cerevisiae as an Antifungal and Antimycotoxigenic Agent

Aflatoxins (AFs) and zearalenone (ZEN) are the most predominant mycotoxins in various food and feed. Therefore, this study aimed to estimate the antifungal activity of Saccharomyces cerevisiae strains and to study their ability to remove aflatoxin B1 (AFB1) and zearalenone (ZEN) in vitro. Data revealed that S. cerevisiae NRLL Y-12633 showed higher antifungal activity compared to S. cerevisiae NRRL Y-1089. On the other hand, S. cerevisiae suspension exhibited higher antifungal activity than S. cerevisiae supernatant. Concerning the removal of AFB1, results indicated that after 30 min. S. cerevisiae NRRL Y-1089 displayed a higher ability to remove AFB1 at a concentration of 5.0 µg/mL with a percentage of reduction reaching 87.20% than S. cerevisiae NRRL Y-12633, which removed 21.00%. As for the removal of ZEN, results showed that after 30 min. S. cerevisiae NRRL Y-12633 successfully removed ZEN at a concentration of 5.0 µg/mL by 94.80%, whereas S. cerevisiae NRRL Y-1089 removed ZEN by 91.80%. Results also indicated that the removal of AFB1 increased by increasing the incubation time, whereas the removal of ZEN decreased by increasing the incubation time. Therefore, it could be concluded that S. cerevisiae strains could be applied as an additive to decrease the concentration of mycotoxins in food and feed.

期刊介绍： Biointerface Research in Applied Chemistry is an international and interdisciplinary research journal that focuses on all aspects of nanoscience, bioscience and applied chemistry. Submissions are solicited in all topical areas, ranging from basic aspects of the science materials to practical applications of such materials. With 6 issues per year, the first one published on the 15th of February of 2011, Biointerface Research in Applied Chemistry is an open-access journal, making all research results freely available online. The aim is to publish original papers, short communications as well as review papers highlighting interdisciplinary research, the potential applications of the molecules and materials in the bio-field. Our aim is to encourage scientists to publish their experimental and theoretical results in as much detail as possible.
