<p>Sequencing data showed that Metionine-γ-lyase was inserted correctly together with Bba_b0034 (RBS), pfrI + B_0034 transformants were grown in 10 ml LB containing antibiotic and miniprepped. Plasmids were digested with EcoRI & SpeI. This was done because insert could enter in 2 ways, need to check for the correct insert.  Correct insert would give us 2132 bp and 566 bp, the incorrect insert will give us 5675 bp and 23 bp. Ran it with 1 kb NEB ladder.</p>

<p>Grew <i>E. coli</i> containing SEVA plasmid 256, 581 and 434 in LB medium with correct antibiotic. Miniprepped them the day after.  Want to create SEVA plasmid that has pBBR1 ori, lacIq-Ptrc promoter and km or tet resistance. SEVA plasmids were digest with PacI and SpeI in order to get the cargo out, want to change the cargo and insert the correct cargo which is the lacIq-Ptrc (in SEVA 434) to backbones from 256 (Km resistant)0 and 581 (tet resistant). For SEVA 256 and 581 alkaline phosphatase was added in the digestion mixture. <br/></p>

Also repeated 2,4-DAPG growth experiment in 100ml with 1L erlenmeyers. This time with:</p>

<p>Sampled 40 ml at t=24h and t=48h. Extracted and concentrated with ethylacetate. <br/>

In addition grew wild <i>P. putida</i> KT2440 on 20μg/ml Kanamycin to see if a lower antibiotic was possible, and there was no growth in 20μg/ml Kanamycin so it is possible to select <i>P. putida</i> with 20μg/ml Kanamycin.<br/>

Grew in duplo’s the following on LB agar plates in order to get 2,4-DAPG production with +/- anitibiotic and 1mM IPTG. </p><br/>

Directed mutagenesis of Chitinase in pSEVA254 performed 3 times with different annealing temperatures (60°C, 50°C and 70°C) and different times of elongation (30 seconds per kb - 50 seconds per kb). None of them worked.</p>
