This week I made great progress in my unknown and unknown
contaminant research. I concluded the msa test on both my microbe and the
contaminant and found that they are different bacteria. I did notice that the
unknown given to me fully turned the msa agar to yellow showing that it was
positive for acid. However the unknown contaminant did not have the same
results and did not show signs of acid fermentation. My unknown is defiantly Staphylococcus
aureus and needs no further testing. The contaminant found on my original
streak plate showed negative for acid in the msa test and needs to go through a
tsi and lactose test. I believe the bacteria that contaminated my sample is Staphylococcus
epidermidis but I will not know for sure until next week. As for my research
project I have found the materials needed to complete the research and I hope
to start setting up the experiment next week. Getting a control group of seeds
planted is my first step then adding endophytes in different amounts will to
each plant will show how the plant microbiome can have an effect on the overall
health and production of the plant.
