Tennis elbow symptoms usually begin gradually. The main symptom is pain, which may begin with a dull aching or soreness on the outer part of the elbow that goes away within 24 hours after an activity. As time goes on, it may take longer for the pain to go away.
When an energy substrate is available, often a simple carbohydrate, and often under anaerobic (lack of oxygen) conditions, fermentation will proceed. Many microorganisms use fermentation as an energy producing pathway. These may include molds, fungi, and bacteria. No, food can not ferment on its own. Fermentation is always a biological process. We often think of food spoilage or fermentation as being spontaneous. But this is due to the fact that we can not see the very small (micro) organisms doing the activity.
Industrial fermentation is the intentional use of fermentation by microorganisms such as bacteria and fungi to make products useful to humans.Fermented products have applications as food as well as in general industry. Some commodity chemicals, such as acetic acid, citric acid, and ethanol are made by fermentation.n the process of sewage treatment, sewage is digested by enzymes secreted by bacteria. Solid organic matters are broken down into harmless, soluble substances and carbon dioxide. Liquids that result are disinfected to remove pathogens before being discharged into rivers or the sea or can be used as liquid fertilizers.
