Transformations of the biobricks K133071, K173003 and I13453 are performed. K133071 will produce CO2 if there's pyruvate present and K173003 will produce CO2 if urea is present. I13453 is a promotor which will work if there's arabinose present.
The biobricks were transformed first into electrocometent cells and later into chemical competent cells from the strain NEb10Beta. After transformations the culture was plated on agar plates with antibiotics. The first transformations didn't work out, but the second did, because then the right competent cells were used.
Experiment 1: Transformation biobricks
Transformation of the biobricks K133071, K173003 and I13453 in NEB10Bèta.
Materials
- Biobricks (Bba_K133071, Bba_K173003 and Bba_I3453)
- Nuclease free water
- LB- agar
- Variable Volume Pipettes
- Sterile pipetpoints
- Chemically competent cells ( NEB10Beta, 1x10^9)
- Heater (42°C)
- Incubator + shaker (37°C and 250 rpm)
- Eppendorf tubes (1,5 and 2 ml)
- Stable outgrow medium for NEB10Beta or SOC- outgrow medium
-Chloramphenicol (40 mg/mL)
Methods
-K173003 --> pSB1C3 backbone, plate 6, well 15N
-K133071 --> pSB1C3 backbone, plate 6, wel 21A
-I13453 --> pSB1C3 backbone, plate 3, well 19O
To be able to use the DNA from the biobricks, they were first diluted in Nuclease free water. This was done by adding 10ul of nuclease free water to the DNA and incubated for 5 minutes at room temperature (18-24°C). After incubation the DNA is transferred to Eppendorf tubes and put on ice.
For the transformation 1 ul of the DNA was added to 50 ul chemically competent cells strain NEB10Beta. The mixture was incubated for 30 minutes on ice. The mixture got a heat shock by putting the tube in a heater (42°C) for 30 seconds. After the heat shock the tube was immediately put on ice for 5 minutes.
For good grow of the cells, 950 ul of outgrow medium was added to the mixture. After mixing the cells with outgrow medium, the culture was incubated for 1 hour at 37°C and 250 rpm.
After incubation the culture was plated onto LB-agar plates. For specific growth of bacteria there was antibiotics added to the plates. The antibiotics that were used, depended on the plasmid. The biobricks used in this experiment were resistent to chloramphenicol (Can). We worked with a work concentration of 35 ug/ml for chloramphenicol. For good results we plated 100 ul undiluted culture onto a plate and centrifuged the rest of the culture. The supernatant was discarded and the pellet was resuspended and plated onto a LB-agar plate. The plates were then incubated by 37°C.
Results
The first transformation was done in electrocompetent cells instead of chemocompetent cells so the first transformation did not succeed.
Conclusion
The second transformation from the biobricks was successful. The bacteria with the biobricks plasmids will be stored by 4°C and can be used for further experiments.
The CFU from the negative controle will be plated on a plate with antibiotics to make sure there isn't a plasmid in the bacteria. The outgrow medium will be sterilized by filter again.

The plates show CFU which can be used for further experiments. The negative controle also has CFU, this shows that the outgrow medium was infected and not sterile.
The plates are stored by 4°C.
Conclusion:
The transformation from the biobricks was successful. The bacteria with the biobricks plasmids will be stored by 4°C and can be used for further experiments.
The CFU from the negative controle will be plated on a plate with antibiotics to make sure there isn't a plasmid in the bacteria. The outgrow medium will be sterilized by filter again.

Testing different amounts of urea and sodiumpyruvate to know which concentrations the bacteria survive.
Experiment 1: Testing different concentrations of Urea and Sodium pyruvate
08-08-18
Testing different amountsof urea and sodiumpyruvate to know which concentrations the bacteria survive.
-First let the LB agarose heat up (95 degrees Celcius)
-Second, weigh urea and sodium pyruvate in beakers (see table 1)
| What | How much | Solution |
| Urea | 1 g | 1 mL purified water |
| Urea | 2,4 g | 2 mL purified water |
| Urea | 4,8 g | 4 mL purified water |
| Sodium pyruvate | 5,7 mL | None |
Table 1: weighing urea and sodium pyruvate for LB agarose plates.
-Purify these substances, so it is free of bacteria. Work beneath the flame and pour it in to plastic 50 mL tubes.
-Pour the LB agarose in the plastic tubes when it's about 45 degrees Celcius and mix gently.
-Pour the LB agarose mix in a petridish and wait until it's dry. Do this for all the plastic tubes.
-Also fill 2 petridishes with LB agarose without other substances (positive and negative control).
-prick a BL21(DE3) bacteria and put it in a 100 mL erlenmeyer with 20 mL culture medium.
09-08-18
Pipette 100 ul overnight culture on each plate, except on the negative control, and divide it. (24h 37 degrees Celcius)
Results
| What | How much | Solution | Result |
| Urea | 1 g | 1 mL purified water | Grow |
| Urea | 2,4 g | 2 mL purified water | No grow |
| Urea | 4,8 g | 4 mL purified water | No grow |
| Sodium pyruvate | 5,7 mL | - | Grow |
| Positive control | - | - | Grow |
| Negative control | - | - | No grow |
Table 1: Results experiment 1
Conclusion
More tests will be done with urea and sodiumpyruvate because with 1 g urea the bacteria live and with 2,4 g urea the bacteria die.
The bacteria survive 5,7 mL sodiumpyruvate so we will test with higher concentrations.

The biobricks J23100, K133071, K173003 and I134353 were sucessfully digested after the second time. After the digestions the biobricks K133071 and K173003 were dephosphorylated and ligated with the inserts J23100 and I13453. This was done in the original backbone of K133071 and K173003, and not another control backbone. To know if the biobricks were right ligated this was done by testing practically. See the experiments: Testing gas production.

| 3 μL | phosphatase buffer (10x) |
| 1 μL | milli Q |
| 1 μL | phosphatase (1 U/μL) |
| 30 μL | Total |
The new DNA concentration of the reaction mix is 0,5 μg/30 μL
The reaction mix was incubated for 10 minutes at 37 °C
The phosphatase was inactivated for 2 minutes at 75 °C
The following vector-insert combinations were ligated:
| Vector | Insert 1 | Insert 2 |
| K133071 | J23100 | I13453 |
| K173003 | J23100 | I13453 |
The original plasmids of the vector and inserts that were digested are about the same size in bp and the ratio vector DNA-insert DNA is determined to be 1:3. Therefore, the amount of insert DNA that was used for the ligation was 140 ng (rounded up to 7 μL of the digestion reaction mix). Because there was only 5 μL left of the K352001 insert DNA, the total 5 μL were used and an extra 2 μL of milli Q water were added to the pre-ligation mix.

Methods

Make 19 agar plates with kanamycine (Kana) (17,5 ul/20mL) and 1 agar plate with ampicillin (Amp) (40 ul/mL). Plate all the transformations on agar plates with Kana , because all the ligations are done in the pSB1K3 (Kana resistence) backbone.
Devide one Amp plate and one Kana plate in about 30 parts. Because the biobrick combinations with biobrick K133116 have originally Amp and Kana resistence, the right backbone plasmid (with hopefully the right ligation) is only growing on the agar plate with Kana.
Results
There is grown n every transformation plates, so the transformations are done well.
There are pink and white colonies present. Only the white colonies will be used for further experiments.

Assessing Gas Production BioBricks in E.Coli
September 14
Different strains of E.coli are tested as negative control. Those strains were: NEB10Bèta, BL21 (DE3), BL21, HB101, DH5alpha and JM109. NEB10Bèta produced the most gas. BL21, HB101 and JM101 produced none/almost none gas. Because BL21 isn't a K12 strain we can not use that one. That is why we will test further gasproduction in HB101 and JM109. And maybe those will be our final E.coli strains.
Experiment 5: Testing different strains of E.coli
Materials
All the following types of bacteria are E.coli:
-glycerolstock BL21
-glycerolstock HB101
-glycerolstock DH5alpha
-glycerolstock JM109
-agarplate with NEB10beta
-agarplat with BL21 (DE3)
Methods
See experiment 1
Make overnight cultures of the following E.coli tribes: NEB10Bèta, BL21 (DE3), BL21, HB101, DH5alpha, JM109.
All the bacteria are de deluted in normal LB agar, LB agar with urea and LB agar with pyruvate.

September 27
From 27-09 until 04-10 more than 200 digestions and 17 gelelectrophoresis have been performed. This was done as a control for our composite parts. We digested with XbaI, Eco01019 and SspI-HF/HindIII. Every restriction-enzyme has an unique place to cut in our constructs. With this we could test if the promoter, backbone and gas production gene was present. However, the digestions didn't show us very good results. Only I1 and J1 looked good. After this we started with PCR.
