Twenty-six strains of Penicillium islandicum Sopp were tested for production of a chlorine-containing peptide (Cl-peptide), which is a hepatotoxin. Highest levels of the mycotoxin were produced in a modification of Wickerham medium. The mycotoxin was isolated by adsorption on charcoal and, after washing the charcoal with acetone-water (1:1), was eluted into n-butanol. Further purification was accomplished by gel filtration. Maximum yields were 10 to 20 mg of toxin per liter of culture filtrate.
对26株冰岛青霉进行了测试,以检测其含氯肽(Cl-肽)的产生情况,该含氯肽是一种肝毒素。在改良的威克汉姆培养基中,该霉菌毒素的产量最高。通过吸附在木炭上分离出霉菌毒素,用丙酮-水(1:1)洗涤木炭后,将其洗脱到正丁醇中。通过凝胶过滤进一步纯化。每升培养滤液的最大产量为10至20毫克毒素。
