1 Answer - Sort by: Date | Rating

    A yeast is a micro-organism and a part of the kingdom Fungi. They are eukaryotic, and reproduce asexually, by budding and also by binary fission. Most of the yeasts are single-celled, i.e., unicellular, though there are some multicellular species as well. Yeasts,as mentioned earlier, are micro-organisms, and are about 3 to 7 microns in diameter. Some yeasts grow to approximately 40 μm in diameter.

    Yeasts do not require light for growth. They grow using organic compounds, and are also termed chemo-organotrophs.

    Yeasts have a lot of good uses. Since they grow in organic compounds, they are used in the fermentation process, to bake bread, manufacture beer, etc.

    However, yeasts can also cause infections in people, as well as spoil good food. Yeasts can spoil food by growing on the food surface and releasing metabolic products that alter the physical, chemical, as well as sensory properties of food.

    Maintaining a medium to high PH environment is a good way to ensure that yeast growth does not happen.
