Conclusion : 
L150 doesn't success, measured size match with the promoter size only, 
 we will check the size of L101 by screening and if it doesn't match with the good size (1827pb) 
 we will try again the ligation : rbs-TetR (S03879) with GFP tripart (E0840).
L151 is ok we have to put a strong promoter before the part rbs-lasR-double terminator :GREAT !

Remarks: 

    L143 and L144 did not work once again. Maybe there is a problem with the digestion,  
 because the primers  used present only two nucleotides after the restriction sites. what we should  
do is cutting pfliL with xbaI and SpeI. As the vector will autoligate, we should use a phosphatase

    For L147 and its control (T4), we do not observe any red fluorescence. It means that the digestion work well, 
because if it was not digested, the strong promoter J23100 should  express mRFP!  
 We will repeat all the ligation anyway.
