With this endospore staining procedure, endospores will stain green while vegetative bacteria will stain red . Observe the demonstration slide of Bacillus anthracis . With this staining procedure, the vegetative bacteria stain blue and the endospores are colorless. Observe the demonstration slide of Clostridium tetani . With this staining procedure, the vegetative bacteria stain blue and the endospores are colorless.
Most motile bacteria propel themselves by special organelles termed flagella .
The rotation of the inner disk causes the flagellum to act much like a propeller. Bacterial motility constitutes unicellular behavior. In other words, motile bacteria are capable of a behavior called taxis. Taxis is a motile response to an environmental stimulus and functions to keep bacteria in an optimum environment. The arrangement of the flagella about the bacterium is of use in classification and identification.
