👉 The term "fermentum" is a Latin word that means "to ferment," which in turn refers to the process of converting one substance into another. It can also refer to the act of producing or producing something by using other substances, such as sugars or starches, for example. In this context, "fermentum" could be used to describe the chemical reaction between certain substances (usually sugars) and oxygen in a fermentation vessel to produce alcohol or carbon dioxide gas.
