摘要:

SummaryThe dominant mold obtained from the Wensleydale cheese is not identical withP. roqueforti.There is at least one marked difference in the structure of the colonies on potato agar. TheP. roquefortiproduces large white areas of closely interwoven mycelium. These have never been noticed in the case of the Wensleydale strain.The reactions on some of the constituents of the media used are different. This difference is usually more a question of degree of growth or rate of change than a direct positive or negative result. These differences may be briefly summed up as follows:1.The Wensleydale strain produces a slight degree of acidity in whey-peptone-litmus-gelatin, whileP. roquefortidoes not.2.The digestion of the casein of milk which has been inoculated withP. roquefortiis four times as rapid as is the case when milk is inoculated with the Wensleydale mold.3.The Wensleydale strain grows less freely than doesP. roquefortion synthetic medium containing saccharose, galactose, levulose, and dextrose, respectively.4.The Wensleydale strain grows more freely on synthetic media containing casein and peptone respectively than doesP. roqueforti.Thanks are tendered to the Departments of Botany and Dairying of the Iowa State College, U. S. A., and to the Department of Dairying of the University of British Columbia, Canada, for facilities granted and assistance given.
