As in the beginning it was planned to put the four modules in vectors with different antibiotic resistance (such as pSB1C3, pSB1T3, pSB1A3 and pSB1K3)  in a single <i>E. col</i>, but the team decided to first insert all of the genes in pSB1C3 so they could be sent to the parts registry.</p>

<p><b>Digestion of NhaS and pSB1C3</b></p>
+
<p>The next step of obtaining the DNA is get only the needed fragment for the project, this would be accomplished through a digestion with the enzymes of the biobrick format:  EcoRI and PstI (In the case of pSB1C3, nhaS and BSMT1 opt.). But in the case of the union module, there is a fusion protein, it means that the digestion of AIDA and L2 (parts of the fusion protein) is with other enzymes, the first with PstI and BglII, and the second with EcoRI and BamHI.</p>

<p>Electrophoresis gel of quantitative digestion of NhaS and pSB1C3. The digestion was made in order to get the plasmid pSB1C3 and the gene NhaS. As a plasmid is differentiated from the insert by its length, it stays in the upper part of the gel while the insert RFP stays below it. Same with NhaS, as insert is stays below the vector pUC57</p>

<p>The problem was that the enzyme that cuts NhaS and pSB1C3 was not available to the team, and it would take a long time to get it. To solve this problem, it was sent the DNA to be sequenced and then prove that the ligation actually occurred, and NhaS was inside pSB1C3. It was used a primer that is from 5' to 3' in the complementary chain:</p>

<p>In the experiment #1, it was tested the hypothesis  in which the NhaS transformed bacteria (red and white) survived to a saline environment with LB agar. Then it order to know if it would survive only in a saline medium, it was designed a second experiment where the bacteria was inoculated in erlenmeyer flasks with only salty water at different concentrations (1%, 2.5% 5%, 10% and 15%). None of all the inoculated erlenmeyer flasks was murky, it means that all of the bacteria was dead.</p>

<p><b>Experiment # 3</b></p>
 +
<p>In the experiment #3 the bacteria's hability to withstand salty environments was again tested, but this time the effect that RFP could possibly have in the expression in the NhaS gene. In this experiment, three groups of bacteria (NhaS+RFP, NhaS and a control group) were exposed to different salinity concentrations to test their resistance to salt. This resistance was given by the NhaS gene. A similar process as the one in the experiment one was followed in which bacteria was cultivated in mediums containing salt at different concentrations, and incubated for 24 hours to appreciate how were the colonies formed. </p>
 +
<center><p><https://2014hs.igem.org/File:Igemcideb2014imagenexperimento3.JPG"/></p></center>
 +
 +
<p>In the experiment, the team had the chance to test the effectiveness of the NhaS-producing bacteria. The results of the experiments were measured in the amount of  bacteria colonies on the petri dish. In some cases the amount of bacteria were  uncountable, because they were spread all over the petri dish, forming a thin film. So it was measured an average size bacteria colony and it was compare with the size of the  petri dish. So it was assume that a completely full  petri dish has an approximately number of 2500 bacterial colonies. There were 3 different types of  bacteria. The ones with NhaS that did not had RFP, the ones with Nhas and RFP, and the bacteria that were used as control (no RFP or NhaS). Each one  of these were introduced into a different salt percentage solution. The  percentage on which the bacteria were tested are 15%, 10%, 5%, 2.5% 1% of salt  on the solution. Also another variable for the experiment was the amount of  bacteria concentration within the solution. These concentrations are shown in  ratios which are 1:10, 1:100 and 1:1000 of a solution with bacteria on the  solution. The experiment were executed twice so it means that there are two  results for each type of bacteria on a given concentration on a given salt  percentage solution. &nbsp; <br />
 +
  The bacteria&rsquo;s  resistance to salinity was expressed in the amount of colonies grown in a  medium with a certain level of salinity due to the certain tolerance to salt  given by the NhaS gene. After the experiment, the data obtained was plotted  into tables for further processing and analysis.</p>

Untitled Document iGEM CIDEB 2014 - Project

Biobricks construction- Return to the top

Here are the results of how the team got the modules of the project

Minipreps

Digestions

Purification

Ligations

Characterization

Minipreps- Return to the top

The first step for building the four modules in a bio-brick format, with the vector pSB1C3 is to isolate the plasmid DNA from the bacteria through a mini prep.

The next electrophoresis geles (Image 1) shows that the extraction of the DNA was performed correctly. At the beginning, it was planned to put the four modules in vectors with different antibiotic resistance (such as pSB1C3, pSB1T3, pSB1A3 and pSB1K3) in a single E. coli, but the team decided to first, insert all of the genes in pSB1C3 so they could be sent to the parts registry.

Image 1. Electrophoresis geles showing the plasmid DNA gotten from mini preps of the bacteria transformed with pUC57-NhaS, pUC57-BSMT1 opt., pUC57-AIDA, pUC57-L2, pSB1C3-RFP, pSB1K3-RFP and pSB1A3-RFP.


Digestions-Return to the top

The next step of obtaining the DNA is get only the needed fragment for the project, this would be accomplished through a digestion with the enzymes of the biobrick format: EcoRI and PstI (In the case of pSB1C3, nhaS and BSMT1 opt.). But in the case of the union module, there is a fusion protein, it means that the digestion of AIDA and L2 (parts of the fusion protein) is with other enzymes, the first with PstI and BglII, and the second with EcoRI and BamHI.

In the digestion made in order to get the plasmid pSB1C3 and the gene NhaS (Image 2. right gel) both were differentiated from their respective insert (RFP) and plasmid (pUC57) by its length. The plasmid stays in the upper part of the gel while the insert stays below it.

The same happened with the digestion of BSMT1 opt., AIDA and L2 (Image 2. left gel) the genes were differentiated by its length.

There is not need of make all the purification process of the fragments gotten in the digestion, easily the ligation can be done. But to make sure that only the pieces that were wanted to ligate, were together, it was done a purification. Then to confirm that there were only the fragments such as pSB1C3, BSTM1 opt. L2 and AIDA, it was made an electrophoresis gel:

Ligations- Return to the top

After the purification of the digestions was made, the fragments were ligated with their respective gene-plasmid. Then bacteria were transformed with those ligations and inoculated in a Petri dish obtaining the next result:

Ligation of NhaS and pSB1C3 [Capture Module] - Return to the top

In the first transformation of the ligation of NhaS and pSB1C3 grew red (expressing RFP) and white bacteria. The Petri dish was not cover by aluminum after its inoculation.

Result of ligation BSMT1 (optimized) and pSB1C3 [Aroma Module] - Return to the top

The main gene of the aroma module, BSMT1 opt. was ligated with pSB1C3, and then transformed in bacteria in order to be inoculated. In the resulting inoculation there were only white colonies of bacteria.

Characterization- Return to the top

Capture module characterization

Once NhaS was in the pSB1C3 plasmid, it was needed to prove it, through a characterization; also there was the question of why were there in the ligation red and white bacteria, if all had the plasmid to chloramphenicol resistance (reason they lived). Which of the two types really had NhaS?. To know with which enzyme make the digestion, it was made a digital digestion of the plasmid and the insert getting the next result:

Image 7. Virtual digestion of NhaS (yellow) +RFP (red) +pSB1C3 (purple) by the enzyme Arsl (blue), showing that its restriction site is repeated two times, one in NhaS and other in pSB1C3.


The problem was that the enzyme that cuts NhaS and pSB1C3 was not available to the team, and it would take a long time to get it. To solve this problem, it was sent the DNA to be sequenced and then prove that the ligation actually occurred, and NhaS was inside pSB1C3. It was used a primer that is from 5' to 3' in the complementary chain:

The result of the sequencing of the mini prep of the bacteria transformed with NhaS in pSB1C3 that showed the RFP production was the next (in 3' to 5' direction):

Viability test of the NhaS gene containing bacteria in salt [Capture Module] - Return to the top

Experiment #1

Bacteria transformed with the capture plasmid were inoculated in Petri dishes with different concentrations of salt

Image 13. All the 18 Petri dishes inoculated with the Control bacteria of all the 9 used concentrations.

All the bacteria containing the NhaS in pSB1C3 (Red and White) survived to a 10% concentration of salt.

None of the control group lived in any concentration of salt.

Image 14. Nine Petri dishes with the maximum concentration of salt (10%) used in this experiment. From up to bottom: NhaS Red in pSB1C3, NhaS White in pSB1C3 and the Control bacteria.


The first time the experiment #1 was performed, transformed bacteria with the capture plasmid were inoculated in Petri dishes with different concentrations of salt, but this time the mayor concentration is higher (15%)

All of the transformed bacteria with NhaS in pSB1C3 (Red and White) lived in the 15% saline medium.

All the control bacteria exposed to any concentration of salt died.

All the control bacteria inoculated only in LB medium (without salt) lived.

Experiment #2 - Return to the top

In the experiment #1, it was tested the hypothesis in which the NhaS transformed bacteria (red and white) survived to a saline environment with LB agar. Then it order to know if it would survive only in a saline medium, it was designed a second experiment where the bacteria was inoculated in erlenmeyer flasks with only salty water at different concentrations (1%, 2.5% 5%, 10% and 15%). None of all the inoculated erlenmeyer flasks was murky, it means that all of the bacteria was dead.


Image 16. Erlenmeyer flasks inoculated with NhaS transformed red bacteria of all concentrations. From left to right: 15%, 10%, 5%, 2.3% and 1%.


Experiment # 3

In the experiment #3 the bacteria's hability to withstand salty environments was again tested, but this time the effect that RFP could possibly have in the expression in the NhaS gene. In this experiment, three groups of bacteria (NhaS+RFP, NhaS and a control group) were exposed to different salinity concentrations to test their resistance to salt. This resistance was given by the NhaS gene. A similar process as the one in the experiment one was followed in which bacteria was cultivated in mediums containing salt at different concentrations, and incubated for 24 hours to appreciate how were the colonies formed.

In the experiment, the team had the chance to test the effectiveness of the NhaS-producing bacteria. The results of the experiments were measured in the amount of bacteria colonies on the petri dish. In some cases the amount of bacteria were uncountable, because they were spread all over the petri dish, forming a thin film. So it was measured an average size bacteria colony and it was compare with the size of the petri dish. So it was assume that a completely full petri dish has an approximately number of 2500 bacterial colonies. There were 3 different types of bacteria. The ones with NhaS that did not had RFP, the ones with Nhas and RFP, and the bacteria that were used as control (no RFP or NhaS). Each one of these were introduced into a different salt percentage solution. The percentage on which the bacteria were tested are 15%, 10%, 5%, 2.5% 1% of salt on the solution. Also another variable for the experiment was the amount of bacteria concentration within the solution. These concentrations are shown in ratios which are 1:10, 1:100 and 1:1000 of a solution with bacteria on the solution. The experiment were executed twice so it means that there are two results for each type of bacteria on a given concentration on a given salt percentage solution.  
The bacteria’s resistance to salinity was expressed in the amount of colonies grown in a medium with a certain level of salinity due to the certain tolerance to salt given by the NhaS gene. After the experiment, the data obtained was plotted into tables for further processing and analysis.

Experiment 2 - Petri dishes

Random people were chosen to smell our bacteria, four people per each concentration. The experiment was performed with three different concentrations of salicylic acid, which were of 10 mM, 20 mM, and 30 mM. All of the samples contained salicylic acid. There was a controlled group grown bellow and above the 32 ºC and a group with transformed bacteria with the Aroma module, also grown bellow and above the 32 ºC; per each concentration.

Those are the words that people used to repeat, or synonyms of what the said, because all the opinions were described in a different way.
