9/1 Lab

On 9/1 lab, I gram stained from plates for the second time. These samples were unknown, so to ensure accuracy, another lab partner helped with the inoculating and staining. I redid my slides and stains twice, because my first round was very much user-error. First, I was waiting for the sample to dry on the slide, and went to heat fix it too soon, so some of the water, I'm assuming with some of the sample in it, slide out of the wax circle I had drawn. I then heat fixed a different sample, after waiting longer for them to dry, and I held it over the flame for too long, resulting in a piece of the slide breaking off. I was still able to gram stain it, but the sample was grey/black under the microscope.

After redoing the slides and gram stains, there was a bit of color in my samples. Unfortunately, there was not much, but this is the most colorful out of all of my samples.

    The gram stains were a pain to do, I had barley any color on mine and I couldn't see what was positive. Then looking under the microscope it was almost impossible to see what I was looking at. I eventually figured it out, but boy was it a process to do

3/24 Lab

3/24/18 was my first day in the STEM lab and in a biology lab, so sorry if this post is a bit confusing or does not make sense because my concept of biology is fairly weak. In this picture, it shows a putative lactonase sample. On line 2, there was no DNA; it was clean. On lines 3 and 4, it shows the bands seen at approximately 800 bpm, and in line 5 there was no band present. In this lab, I learned a lot about the micro-pipets and which ones to use during specific steps of this process. I am still very new to all of this, so hopefully my future posts will be more understandable.

10/16 + 10/19 Lab

10/16 was another day of filling a well plate with acetic acid. 10/19, my lab partner and I filled three new wells plates with our 3 salts and our D. Gobi, just like our original two plates were, with an added combination this time (AB+AC+BC). Each plate had 2 salts in that combination.

9/21-9/22 Lab

During this lab weekend, my lab partner, Baylee, and I began planning out our biofilm experiment with Chad, one of the peer mentors in this STEM lab. After researching much about biofilm and effects that can vary the growth or reduction of biofilm, my lab partner and I decided testing the effect of salt concentration on biofilm would gather information that may not already be out there. For this experiment, we will be using D. Gobi, and testing salts MgCl ₂,  MnCl ₂ , and NaCl.
