Abstract

Three models based on sigmoidal plotting were tested for their ability to describe zearalenone adsorption on Saccharomyces cerevisiae cell walls in vitro. All three models closely fitted the experimental data, but Hill's equation gave the most accurate parameters, and provided information on the physical and chemical mechanisms involved in the adsorption of mycotoxin on yeast cell walls.

摘要

测试了基于S形曲线绘制的三种模型描述玉米赤霉烯酮在体外对酿酒酵母细胞壁吸附作用的能力。所有这三种模型都与实验数据紧密拟合，但希尔方程给出了最准确的参数，并提供了有关霉菌毒素在酵母细胞壁上吸附所涉及的物理和化学机制的信息。
