A Mistake & A Tea Streak/ Broth
Class: Thursday, September 12, 2013
Our second trial of the potentially antibacterial air sample, it turns out, was not able to be verified. Yet. Dr. Pathakamuri informed us that our streaks on the agar plate were too far apart for any antibacterial activity to occur or be observed. We know this because if there were any antibacterial activity, the streak that would have been inhibited, would not have grown at all.
Our plan of action is to try again, for the third time: in this trial, we streaked the bacteria closer to each other on the plate, to allow for interaction.
In the meantime, Juliet has quite the interesting cup of tea. She likes to grow her own natural cultures...in her dorm room. Juliet let the bottom of her hibiscus tea sit in her room for about a week, and she made an exciting observation - black growth occurred on the surface, as well as red, fuzzy sediment. She brought it into class, and we decided to do a streak plate as well as a broth culture of the growth, out of microbiologic interest (is that even a word?)! We stored the tea streak plate and broth culture in room temperature incubator.
