Gram Positive Bacteria
Gram Positive Bacteria are a type of bacteria that have a unique cell wall structure due to the presence of a high number of peptidoglycan molecules. This feature can be identified under a microscope by a process known as Gram staining, which results in a characteristic purple colour. Gram Positive Bacteria are key players in many naturally occurring, beneficial microorganisms in the environment, such as lactic acid-producing probiotics and soil microbes for plant growth. They are also known to cause diseases in humans, such as strep throat, pneumonia and food poisoning. Due to their importance in health and disease, Gram Positive Bacteria are a major research focus and understanding their structure will help us to better understand their role in the environment.
