  When reading your results from identifying a Bacillus species, you see that your BEA has turned black throughout the tube.  How would you interpret your result?

You isolate two Bacillus species, Bacillus subtilis and Bacillus megaterium. B. subtilis is positive for the BEA test, and B. megaterium is negative.  Name 1 ingredient in the BEA that allowed you to differentiate between species.

What 2 antigens are present on the surface of a Staphylococcus aureus bacterium that facilitate the Rapid testing of this organism?  Note: 2 answers required

What are the 2 genes found on the pGREEN plasmid used for transformation? Note: 2 answers required  

What enzyme is necessary for the breakdown of the substrate in this media?

In order to accurately interpret your water micro results, what 2 observations must be made?  

Match the ingredients on the left with the correct media on the right.

List a piece of media used since the last practical in which there are NO pH or color indicators (prior to inoculation).
