Experiments

For [B]

• The following inductions were done in 50 mL Glu M9 with [aTc]=10 ng/mL (10*50=0.5 ug == 50 uL of 10 ug/mL aTc)

pT LuxI.C: 2 flasks - 1 ul/mL == 50 uL
                  - 0.1 ul/mL == 5 uL

• pL.LuxR.Y.pR.C and K12z1 were inoculated in LB.

• The required OD flask (0.205) was filtered.

• Seven dilutions for pL.Lux.R.YpR.C with 1:1 (AI supernatant:new 2xM9) were made in two sets along with -ve control: K12z1; AI+new M9 med;(500 uM IPTG) (2 tubes).

• Also 1 dilution of new M9 medium with pLLuxR.YpRC was made (two sets).

For [A]

• Seven dilutions of AI medium for pLLuxR.YpRC were made with 50 old:50 new 2xM9 along with -ve control: K12Z1 (1000 uM IPTG).

• One dilution (500 uM) of K12Z1 medium for pLLuxR.YpRC with 50 old:50 new 2xM9 was made.

• One dilution (500 uM) of new M9 medium for pLLuxR.YpRC was made.

For [C,D]

• Inoculated pT.LuxI.C in LB.

Microcopy

• pT.LuxI.C that was growing in the flask before filtering was imaged.

• pL.cfp imaging done.

• Open Loop samples [A] imaging done.
