Applications of BBa_K1413002

We prepared a protocol test to evaluate our Biosensor: E.coli (DH5apha) was grown overnight in M9 medium at 37 °C and then diluted 100-fold to an OD of 0.01 in fresh M9 medium containing Chloramphenicol in 96-well plates. After 6 hours’ of culture at 37 °C, each culture (200 μL) was centrifuged at 2500 r.p.m. for 15 minutes and was suspended in 200 μL of fresh M9 medium containing phenol of different concentrations Then the fluorescence intensity of cultures was measured by microplate reader (TECAN).

TECAN measurement of fluorescence during 11h growth, 37 C°, M9 media (0,4% glucose). The values were obtained by substracting raw Fluorescence values of bacteria exposed to phenol by fluorescence of media (M9) then dividing by corresponding OD600.
