Daisy Mora October 17, 2017 MIC 201 L Daniel Miller MIC 201 Lab #2 Discussion In Part 1 of lab 2, we exposed 7 TGY and 1 SGA plate to 8 different types of bacteria sources. In the first TGY plate, we observed it was exposed to air, had 4 colonies that varied in shades of off-white and yellow, colony shape was circular and clustered near each other. Our second TGY plate was exposed to soil but due to an unforeseen error, we were given sterile soil. As discussed in class the soil was borrowed from the Botany Department where they autoclave their soil to avoid having contaminated plants. The third TGY plate was exposed to the bacteria under Dan’s shoe. The 70 colonies on this plate were a distorted circular shape, colored light yellow and ranged in size. I found the highest number of colonies in the TGY plate that was swabbed with the bottom of Dan’s shoe. Based on the morphology, Dan’s shoe had the biggest microbial diversity. The last four plates were sectioned off into quadrants. The fourth plate was exposed to human hair. In my quadrant, I observed 1 colony that ran the length of the hair and
