Maldi-tof can be used to identify bacteria directly from positive blood culture bottles after extracting bacterial proteins alternatively, organisms growing on culture media can be identified in minutes because the pre-processing steps required to extract the bacterial proteins are not required. Additionally, because bacteria are microorganisms, visual identification is not always possible, and is never easy genetic testing is possible for some well-known bacteria, but it is expensive and time consuming. To introduce and demonstrate various steps involved in the identification of a bacterial unknowns from a mixed culture of organism. Identification of a unknown bacterium essay sample although bacteria is microscopic in size, it is largely important in the healthcare field, environmental work, food preparation, as well as many other industries.

Identify the unknown bacterium using biochemical tests and various methods that had been learned from previous the microbiology laboratory class identifying the unknown bacterium was determined by separating and differentiating possible bacteria based on specific biochemical characteristics. Unknown b, bacillus subtilis, was first gram-stained to determine the shape of the bacterium once it was determined that it was a rod-shaped bacterium, only two possible options were left: bacillus subtilis and bacillus cereus. Unknowns - 1 identification of unknowns in this exercise, you will draw upon many of your new skills to identify unknown bacteria you will be given three bacterial cultures and asked to identify each to the level of genus.

The importance of identifying unknown bacteria is very important for one reason, bacteria does not stay in the same form, it's mutating all the time i believe, if doctors need to treat some bacteria with antibiotics, they need to identify first, what type of bacteria they dealing with. A bacterium with thicker cell walls is known as gram positive bacteria because it retains the first stain and does not absorb the second one, while a gram negative bacterium has a thinner cell wall and absorbs both. Describe how staining and biochemical tests are used to identify bacteria explain how serological tests and phage typing can be used to identify an unknown bacterium. Second, utilizing those techniques allowed for the identification of two unknown bacteria this aspect was crucial for many reasons within the medical field, knowing what bacterium a patient has been infected with could mean the difference between life and death.
