This experiment was successful in showing the wide variety of organisms found in biofilms that form on a toothbrush. Using selective and differential agar plates, a total of 9 different colony morphologies were observed from the same source of inoculum. This clearly shows that a variety of organisms can be present in a biofilm simultaneously. If the toothbrush had been put in the saline immediately after being used by my lab partner, I would expect the number of colonies to increase significantly. I think that due to the toothbrush drying out between the time it was used and the time it was put in the saline, the number of microorganisms available to be captured from it decreased. Despite this, this experiment clearly shows the bacterial diversity present in our mouths and on biofilms on our toothbrushes.

Stating a sentence or two on the background of your experiment could be helpful . Also, I'm pretty sure you should write out nine rather than 9. 

It just jumps into the middle of something with no rprior context or intorduction.  Towards the end of the paragraph the flow also getss choppy, but overall well written

I do not think in scientific writing you're are supposed to use statements such as "clearly shows" I think you would just write "shows"
