Bacteria, yeasts, and mold are microorganisms associated with foods. The individual microorganism cannot be seen without the aid of a microscope. The size of these microorganisms are measured in microns (1 micron is 1/1000 of a millimeter or U25,40A of an inch).hen enough salt or sugar is added to a food, the water activity will be lowered to a level that will prevent microorganisms from growing. 1  In general, bacterial glowth is inhibited by the addition of 5-15% salt. 2  To inhibit mold growth, 65-70% sugar must be added.
In general, there are five types of microbes: 1  cellulolytic bacteria: digest fiber. 2  proteolytic bacteria: break down protein. 3  lactic acid-producing bacteria: digest starch. 4  protozoa: produce volatile fatty acids. 5  fungi/yeasts: break down fiber. 6  other bacteria: produce B-vitamins.he products of forage digestion are volatile fatty acids, which horses use for energy. Humans have some microbes that should stay in balance as well, although they pale in number and function compared to those of herbivores.
