Abstract

At 20 degrees C, aflatoxin B1, at a sublethal dose, decreases the activity of alkaline phosphatase (EC 3.1.3.1), alpha-glucosidase (EC 3.2.1.20), esterase (EC 3.1.1.1), chymotrypsin (EC 3.4.21.1), leucine aminopeptidase (EC 3.4.11.1), and phosphoamidase (EC 3.9.1.1) biosynthesis in Bacillus thuringiensis (Berliner). In contrast, at 41 degrees C no significant decrease was observed. At this temperature, the mycotoxin is not destroyed or metabolized and bacterial cells are resistant to the toxin.

摘要

在20摄氏度时，亚致死剂量的黄曲霉毒素B1会降低苏云金芽孢杆菌（Berliner）中碱性磷酸酶（EC 3.1.3.1）、α-葡萄糖苷酶（EC 3.2.1.20）、酯酶（EC 3.1.1.1）、胰凝乳蛋白酶（EC 3.4.21.1）、亮氨酸氨肽酶（EC 3.4.11.1）和磷酸酰胺酶（EC 3.9.1.1）的生物合成。相比之下，在41摄氏度时未观察到显著下降。在此温度下，霉菌毒素不会被破坏或代谢，细菌细胞对该毒素具有抗性。
