Bacterial culture from a trainer. Scanning electron micrograph (SEM) of Corynebacteria. Corynebacteria are Gram-positive rod-shaped bacteria that are widely found in nature. Bacteria flourish in warm, moist places, and feet with more than 250, 000 sweat glands are a perfect home. As our feet get hot, they perspire. The sweat evaporates and cools them down, but by wearing shoes and socks, the liquid has nowhere to go, creating a perfect environment for microbes. The actual odor is a by-product of the bacterial metabolic processes. They ingest various salts and minerals, and excrete waste products. The main waste product that causes foot odor is isovaleric acid, which is a fatty acid, with a penetrating smell. Magnification: x2600 when printed at 10 centimetres wide. | |
