. Pharmaceutical bacteriology. Bacteriology; Disinfection and disinfectants. CHAPTER XIII YEASTS AND MOLDS The organisms commonly designated as yeasts and molds, though not belonging to the bacteria (Schizomycetes), are of the greatest importance in^human economy and play a most active part in life. Some of them are most beneficent while others are very injurious to health. The yeast organisms (Saccharomyces) cause the alcoholic fermentations in saccharine.

This^mould is found on stale bread, damp leather, gloves, etc. solutions. Many of the mold group cause skin and other diseases. They all belong to the plant division fungi. The more important species may be grouped under three orders, as follows: I. Phycomycetes. (Zygomycetes-.) Zygospore formation. 1. Mucor corymhifer. 2. Mucor mucedo. Both are found in tissue infections. 294.
