Abstract
Methods of plating are described for the estimation of infecting organisms in large samples of pressed baker's yeast. These include the use of 12-in. diam. assay frames as giant petri dishes, on which 1–10 g. of yeast can be plated. Two new media, based on xylose and succinic acid, are used for the estimation of Oospora lactis which is a common contaminant, and the medium containing succinic acid is also useful for tracing wild yeast infections. Succinate broth has shown promise for the estimation of O. lactis in samples of yeast greater than 100 g.Keywords
