Bacteria Classification by Gram Staining
The Shape was noted as Bacilli (Rod-like) shaped cells; a gram variable shape, distinct in either Gram Negative or Gram positive bacteria.
The final colour of the cells were stained pink by the Safranin showing the de-coloration of the crystal violet proving the bacteria is of the gram negative class.
Under oil immersion the cells became more sparse and under the high powered lens of the microscope spores could be seen, as little bubbles, in the cells. This tells us that the bacteria was in its terminal state.
The presence of spores in the bacteria at its terminal state tells us that the bacteria could be an old culture. Old bacteria cultures which are gram positive tend to de-colour, yet more slowly than gram negative bacteria. The speed of de-coloration was not inspected very clearly thus no further conclusion could be reached, yet it is possible that this an old culture of Bacilli shaped Gram Positive bacteria.
