Why does a bacterial yard appear?
Why does a bacterial yard appear? Bacterial yard is a term utilized by microbiologists to explain the look of bacterial nests when all the private nests on a Petri meal agar plate combine to form a field or mat of germs.
What triggers a bacterial nest to form? As the germs take in the nutrients, they start to grow and increase. This produces thousands to millions to billions of cells that start to accumulate, ending up being noticeable to the naked eye. This stack of cells stems from one cell and is called a bacterial nest.
