Some bacteria acquire resistance to antibiotics by gaining genes that code for drug efflux pumps. These efflux pumps are proteins that move the drug from the inside of the cell to the outside before it is able to disrupt cellular processes. Explain the process used by a bacterium to produce these efflux pumps.

You are studying bacteria in a lab setting. You want to know if your bacterium is able to use citrate as a carbon source and ammonium as a nitrogen source. To complete this test you use citrate agar, which contains 5g NaCl, 2g Sodium citrate, 1g Ammonium dihydrogen phosphate, 1g diphosphate, 15g Agag, and 0.08g bromothymol blue. Bromothymol blue is a pH indicator. If a bacterium is able to grow and use the citrate and ammonium salts the pH increases and the media turns blue. How is this media described?
