Sensynova Framework (Psicose Detector + Connector 1A (complete) - dCell)
The part BBa_K2205023 was designed as a detector unit of the Sensynova multicellular framework for biosensors development (Figure 1) as a collaboration with the Evry Paris-Saclay 2017 team.
This part was made to test the modularity of the system by replacing the IPTG detector module of the Sensynova platform with the psicose biosensor created by the Evry Paris-Saclay 2017 team.
This part consists of the Evry psicose biosensor controlling the production of part BBa_K2205008, our connector 1.
This system works through the repression of the psicose sensitive synthetic promoter except in the presence of psicose, freeing up the promoter and subsequently activating the transcription of connector 1 and therefore triggering the following modules of the platform.
A preliminary qualitative assay was carried out as an initial test for this construct. Co-cultures of Psicose detector, processor unit and sfGFP reporter(BBa_K2205015) were inoculated and grown overnight in LB+chloramphenicol (12,5ng/ul).
The day after the cultures were diluted at OD600: 0,1 and mixed together to obtain co-cultures with ratio 1:1:13 (detector:processor:reporter). The samples were supplemented with 33.22 mM Psicose to induce the expression of quorum sensing molecules and eventually achieve the reporter visualisation (Figures 3).
