1. Grow MG1655 in Arabinose overnight in advance. 2. Mix 19.8 mL of M9 medium, with 0.2 mL of cells - denote as MA (MG1655 grown on Arabinose, diluted 1:100 with M9). 3. Prepare a row in a 96 plate: 1. Put 150 uL of 20% Arabinose in the first well 2. Put 100 uL of MA in all of the other 11 wells in the row 1. For i = 1..11 1. Pick up 50 uL (third) out of well i 2. Insert into well i+1 and mix 4. Fill every well in a new 96 plate with 145 uL of MA 5. Move 7.5 uL of the row in plate 1 into each row in plate 2 (i.e. dilute the arabinosewith MA by 1:20) Now we get, 1% (~ 20% / 20) Arabinose inside 150 uL of MA for the first column, 0.333% in the second column, 0.1111% in the third, and so on... 6. Add 100 uL of Oil in each well. 7. Grow in 37 degrees and measure the OD during 24 hours (300 times).
