There are many types of bacteria that can be found in all environments. Each bacteria has a different morphology which includes shape, texture and pigment production. These bacteria also have different dietary requirements, which are important in being able to identify a microorganism. Microorganisms are a diverse group containing all bacteria, a single-celled prokaryotic organism found in all types of environments, a single-celled archaea microorganism that lacks nuclei, and almost all microorganisms are protozoa, a single-celled eukaryotic organism. By identifying the causative agent of a bacteria in an individual, an antibiotic can be developed to prevent health problems. Microorganisms are also used to make certain food products for human consumption. An example would be the production of yogurt. It contains probiotics which help, among other things, to fight against digestive abnormalities. Probiotics are microorganisms consumed to provide health benefits to the body. Probiotics work by replacing disrupted microbes with microbes useful for digestion. With the methods that have been...
