Abstract
Penicillium expansum strains grown on Capek-Dox liquid medium excreted patulin to the medium. Its amount increased until day 12, then smaller amounts of the toxin were observed. Maximum patulin excretion took place at 25 degrees C, pH 6, although at 5 degrees C, pH 3 the presence of this mycotoxin was also observed. The highest amount of patulin produced was observed in medium containing fructose.
摘要
在卡氏-多克斯液体培养基上生长的扩展青霉菌株会向培养基中分泌展青霉素。其分泌量在第12天前不断增加，之后观察到毒素分泌量减少。展青霉素的最大分泌量出现在25摄氏度、pH值为6的条件下，不过在5摄氏度、pH值为3的条件下也观察到了这种霉菌毒素的存在。在含有果糖的培养基中观察到展青霉素的产量最高。
