Unknown Bacteria Lab Report Sample

Unknown Bacteria Lab Report Paper The two streak plates made from the mixture of unknown bacteria showed two different colony morphologies. Colonies of Bacteria A were translucent in color, circular in form, with entire margins and a smooth surface. Colonies of Bacteria B were cream colored, irregular in form, with undulate margins and an ambulate surface. Two different morphologies allowed Gram stains to be performed on each of the bacterium. Gram staining of Bacteria A revealed pink, rod-shaped cells signifying that the bacterium was Gram-negative and rod-shaped. Next, an oxides test was performed to eliminate one or more of the bacterium choices. P. Organisms was eliminated as the identity of the bacterium when the oxides test results were negative. An EMBED plate of the bacteria was examined to identify whether the bacterium was S. Typhoid or E. Coli. The growth on the EMBED plate was shiny and metallic green, meaning that it was positive for lactose fermentation. S. Typhoid exhibits intermediate lactose fermentation with pink or purple growth on an EMBED plate, so it was eliminated as the possible identity of Bacteria A. To confirm the identity of Bacteria A as E. Coli, an Underwrote test inoculated with Bacteria A was observed. The Bibcock confirmed the identity of Bacteria A as E. Coli. Gram staining of Bacteria B revealed purple, rod-shaped cells signifying that the bacterium was Gram-positive and rod-shaped. The shape of the bacterium eliminated Cisco-shaped S. Erasures and S. Epidermises as possibilities for the identity of Bacteria B. Next, an endoscope stain of the bacteria was examined to identify whether the bacterium produced spores or not.
