pH Sensors
Possessing the ability to monitor the brewing process of kombucha without disturbing the microenvironment and using a very visible color reporter would allow for greater insights as to how the populations of organisms and pH may change due to competition amongst other bacteria and yeast in the beverage and SCOBY of the kombucha. The byproducts produced by the kombucha as it brews causes the tea to become more acidic, leading to our team searching for pH sensitive promoters, and for ways to implement these into kombucha.
Though an acidic sensor was what was required for our kombucha analysis, the identification of sensors in other areas of the pH spectrum were explored as well. Three sequences were identified, the CadC operon for the acidic range, CpxA-CpxR complex for the neutral range, and the P-atp2 promoter from the BioBrick Registry (BBa_K1675021) for the basic range.

Project Achievements
You can also include a list of bullet points (and links) of the successes and failures you have had over your summer. It is a quick reference page for the judges to see what you achieved during your summer.
- A list of linked bullet points of the successful results during your project
- A list of linked bullet points of the unsuccessful results during your project. This is about being scientifically honest. If you worked on an area for a long time with no success, tell us so we know where you put your effort.
