👉 Closterosporia is a genus of bacteria that belongs to the family Streptococci, which are known for their ability to infect and cause diseases in humans and other animals. They are characterized by their large numbers of cells, often found in the gut or through external colonization. Clostridiums are particularly well-known for their role in the fermentation process, as they produce lactic acid, a byproduct of this process that can be used to make cheese and yogurt.
