Laboratory Notes
☞☟ Week1 (May 16–May 22)
In order to make sure the efficiency of our "consumer", we should first knock out the luxS gene in our engineering bacteria GR286(a simplified strain of Bacillus amyloliquefaciens LL3). We used a markerless gene replacement method to knock out the luxS gene.
Construction of targeting vector : the upstream and downstream of luxS gene were combined by over-lapping PCR and ligated into plasmid pKSU.
pKSU-ΔluxS was transformed into GR286, and positive clones were selected.

The transformants were cultured at 42oC with chloramphenicol to select single-crossover clones.

☞☟ Week2 (May 23–May 29)
The single-crossover strains were then cultured in LB medium and passaged every 12 hours for 4 generations.
The last generation was cultured in medium with 5-fluorouracil to select double-crossover clones. Regretfully, we didn't get the double-crossover clones.

☞☟ Week3 (May 30–Jun 05)
Transformants were cultured at 42oC with chloramphenicol again and the single-crossover clones were selected successfully.

The single-crossover strains were then cultured in LB medium and passaged every 12 hours for 4 generations.
The last generation was cultured in medium with 5-fluorouracil to select double-crossover clones. We finally obtained our aimed strain—GR286ΔluxS.

☞☟ Week4 (Jun 06–Jun 12)
The GR286ΔluxS strain was cultured and made competent for future use.
The lsrACDB gene from Bacillus thuringiensis was cloned and ligated to T-vector.

After restriction enzyme digestion verification, the positive clones were then sequenced. Unfortunately, the sequencing result showed some mutations inside the target gene.

The gene cloning process was repeated but there were still some mutations.
We finally decided to request the gene company to synthesize the lsrACDB gene.

A strong promoter C2 was cloned from former kit and luxS gene was cloned from GR286.

The plasmid was transformed into GR286 by electroporation.[Failed]
☞☟ Week7 (Jun 27–Jul 03)
This week, we tried to use different voltages to transform the plasmid. Sadly, all of these attempts rendered negative results.
We considered whether the luxS gene is toxic for GR286, and the bacteria tends to reject the gene when a strong promoter is inserted upstream of it. So, we planned to use inducible promoter to reconstruct our expression vector.
The plasmid pWH1520 contains a strong xylA promoter originating from Bacillus megaterium, and transcription initiated by this promoter is xylose-inducible. Also, the gene of interest carries its own ribosome binding sequence (RBS) and translation initiation codon. Based on these points, we redesigned primers.

☞☟ Week10 (Jul 18–Jul 24)
We have received the product of synthetic lsrACDB gene. We first used restriction-ligation method to ligate lsrACDB to plasmid pWH1520, but we failed to select positive after several tries.

Considering that the lsrACDB gene is a large fragment (4500bp), we used ClonExpress technique to clone the gene again to improve the efficiency of ligation. The lsrACDB sequence was divided into two parts and they were cloned separately. Then the two segments were ligated to the plasmid pWH1520 and the recombinant vector was transformed into DH5α. After that, verification PCR was used to select the positive clones. However, we didn't get a good result.
☞☟ Week11 (Jul 25–Jul 31)
We learnt a new method called circular polymerase extension cloning (CPEC) for high-throughput cloning of complex and combinatorial DNA libraries, and we decided to use this method to try to ligate our lsrACDB gene. It's encouraging that we succeeded to ligate the lsrACDB gene to the plasmid pHT-01.
☞☟ Week12 (Aug 1–Aug 7)
Since we have already successfully constructed "supplier" and part of "consumer", we decided to measure the growth curve to explore the function of our "controller".

Cultured media of our supplier was tested for the presence of AI-2 by inducing luminescence of Vibrio harveyi reporter strain BB170.
☞☟ Week13 (Aug 8–Aug 14)
For our consumer, we should also overexpress the lsrK and lsrFG gene for phosphorylating and degrading phosphorylated AI-2. We used ClonExpress technique to clone the two genes and ligate them to plasmid pHT-01 successfully.
We co-cultured the supplier with BB170 and tested the fluorescence intensity to explore the function of supplier. (negative result)

The lsrK gene was purified by gel extraction. Then, both the lsrK segment and pTrc-lsrACDBFG vector were treated with restriction enzyme. After that, lsrK gene was ligated to linearized pTrc-lsrACDBFG, and the ligation product was transformed into E.coli K12.
