This is important in the medical field because identification of unknown bacteria can help treat a patient by knowing the contributing source of a disease. Also, knowledge of different bacteria helped others make antibiotics that are used today. Bacillus cereus, a commonly occurring pathogen which can survive in remarkably hostile conditions, is typically found in soil.

A known Gram positive coccus bacteria will be used alongside an isolated Gram positive unknown bacteria for comparison to aid in the ability to identify the isolated organism to the genus level.

There are many reasons for identifying an unknown bacterium. Some reasons to identify an unknown bacterium could help one determine if the unknown could cause illness in living things or help make antibiotics to kill bacteria that can cause some illnesses.
