A total of 123 isolates of Cladosporium spp., Exophiala spp., Fonsecaea spp., Lecythophora hoffmannii, Phaeoannellomyces werneckii, Phialophora spp., Wangiella dermatitidis, and Xylohypha bantiana were tested for proteolytic activity by using 26 different formulations of gelatin, milk, casein, and Loeffler media. Other physiological properties examined included hydrolysis of tyrosine and xanthine, sodium nitrate utilization in Czapek Dox agar, and thermotolerance. Isolates of Exophiala jeanselmei, Fonsecaea compacta, Fonsecaea pedrosoi, W. dermatitidis, and X. bantiana lacked proteolytic activity. Proteolytic activity was variable among the remaining species, depending on the type of medium used. Thermotolerance had value in distinguishing some taxa.
总共对123株枝孢属、外瓶霉属、瓶霉属、霍夫曼离蠕孢、威尼克氏裴氏瓶霉、瓶梗霉属、皮炎万吉拉霉和班氏木丝霉进行了测试,采用26种不同配方的明胶、牛奶、酪蛋白和吕氏培养基检测其蛋白水解活性。检测的其他生理特性包括酪氨酸和黄嘌呤的水解、察氏琼脂中硝酸钠的利用以及耐热性。琼氏外瓶霉、紧密瓶霉、裴氏瓶霉、皮炎万吉拉霉和班氏木丝霉的分离株缺乏蛋白水解活性。其余物种的蛋白水解活性各不相同,这取决于所用培养基的类型。耐热性在区分一些分类群方面具有价值。
