Moving Forward

Hello everyone, hope you all had a great week so far. Well as my title states, I moved forward in my project to diluting the yogurt before putting it on a TSA plate. With eleven products to dilute and plate I decided to split the products into three group; two groups of four and one group of three. I diluted and plated the first group of four products on Tuesday the 4th and the second group of three products on Wednesday the 5th. Out of the first group, only one plate had growth on it (I am looking for Lactobacillus or Streptococcus) the other three had nothing. From the second group the same thing happened only one plate had growth and the other two had nothing. The two plates that had growth were the Fry’s buttermilk and the Mountain High plain regular yogurt. However, the two plates had too much growth to count so I will be re-doing them next week with a lower amount on the plates. As for the plates that had nothing I will also re-doing them but this time I will be changing the dilution to a lower solution. Next week will be a busy week full of re-dos and finishing diluting and plating the products I did not get to this week.

The two top pictures are of all the equipment I used to dilute and plate. The bottom two pictures are of the plates that had growth. Second to last picture is the Fry's buttermilk and the last picture is the Mountain High plain regular yogurt.
