7 . 1 3 F a l l 2 0 0 8 P a g e | 1 Characterization of phenazines in Pseudomonas Concept P. aerugenosa produces a number of small molecules known as phenazines. They are often redox active, and can be detected through spectroscopic analysis. Protocols Run through these protocols with wild type PA14, the melanin overproducing mutant Δ hmgA and Big Blue to establish the assay methods before starting with the CF isolate library. All of these strains can be found in the lab’s strain collection. See the stellar site for the list of strains and ask a TA to help you get these strains from the lab stock. LB Media Liquid LB: 25 g Difco LB /liter deionized water. Autoclave for 35 min on fluid cycle. Plates: add 15 g bacto agar to 1 liter liquid LB before autoclaving. Let cool to ~50 o C, then pour.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
