[Moulds of bakery dusts (author's transl)].
A total of 260 samples from bakery dusts were investigated. The samples were taken in the great part with the sedimentation-method. A large concentration of moulds was found in the meal-room. The fungal flora was here charcterized by species of Rhizopus nigricans, Mucor and Circinella. With a new volumetric sampler a total quantity of 8 680 fungus spores of particles in 1 m3 was registrated. By a re-examination we found 4473. In the baker's rooms besides moulds (Aspergillus, Penicillium etc.) the yeasts (Saccharomyces cerevisiae, Candida krusei) dominated. With the swab-method it was possible to found reservoirs of Aspergillus flavus, Aspergillus ochraceus, and Aspergillus niger. In the small bakeries the fungus Endomycopsis burtonii (Trichosporon variable) was most isolated.
