<span id="1"><strong><h1>Disc Experiment 1</h1></strong></span>
+
-
<p>We prepared an experiment like the disc experiments methods used to see  antibiotic effectiveness, in order to see the effect of B. Subtillis with LALF on E. Coli.</p>
+
-
<p>By adding E. Coli on Bacillus Subtilis;</p>
+
-
<p><strong>Plate A1);</strong> We put E. Coli on the B. Subtilis with LALF (K541915) biofilm. For his purpose we first prepared acorn starch with liquid LB medium and added 100 ul B. Subtilis liquid medium as a point over it. For a qualified biofilm we incubated it for 24 hours at 37˚C.</p>
+
-
<p>Later we added 10 uL E. Coli with RFP as a single point and again incubated it.</p>
+
-
<p><strong>Plate A2);</strong> In order to understand whether LALF protein or another factor killed E. Coli on the Bacillus biofilm we prepared the same contrivance with a B. subtilis biofilm that doesn’t produce LALF protein or  doesn’t have antibiotic resistance. So we could understand if the B. Subtilis biofilm itself not LALF, inhibited the growth of E. Coli.</p>
+
-
<p><strong>Plate A3);</strong>At this contrivancethe B. Subtilis we used for biofilm didn’t includeLALF protein but had antibiotic resistance. Why we didi this is we knew that there would be a color difference between Plate A1 and A2 but we woluld like to know if the antibiotic would prevent E. Coli with RFP from having color.</p>
+
-
<p><strong>Plate B1);</strong> We spreaded B. Subtilis with LALF  over a normal lb medium. We put E. Coli as a single point while the Bacillus spread is fresh. We aimed to see if B. Subtilis could kill E. Coli without forming a biofilm.</p>
+
-
<p><strong>Plate B2);</strong> We prepared this plate as a control plate of Plate C. For thşs we prepared the same contrivance with only B Subtilis that doesn’t produce LALF protein or doesn’t have antibiotic resistance in order to be sure that if the EColi of the plate B1 does not grow the reason for this is LALF protein.</p>
+
-
<p><strong>Plate B3);</strong> In this contrivance we spread B. Subtilis that doesn’t produce LALAF protein but has antibiotic resistance and added E.Coli with RFP as a single drop over it.</p>
+
-
<p>By adding E. Coli over B. Subtilis ;</p>
+
-
<p><strong>Plate C1);</strong> We added 100 ul liquid culture of B. Subtilis with LAFL (k541915), over the normal lg medium applied with E. Coli with RFP,as a single drop.</p>
+
-
<p><strong>Plate C2);</strong> Over the fresh spread of E. Coli, 100 ul of liquid culture of B. Subtiis not producing LALF or doesn’t have antibiotic resistance as a single drop.</p>
+
-
<p><strong>Plate C3);</strong> At this contrivance we added B. Subtilis that doesn’t produce LALF but has antibiotic resistance over the fresh spread of E. Coli with RFP likewise.  We aimed to see the affect of antibiotic resistance over E. Coli with RFP ,by using B. subtilis with and without antibiotic resistance.</p>
+
-
<p><strong>Plate D1);</strong> We added supernatant of B. Subtilis with LALF as a single drop over fresh spread of E. Coli with RFP.  Because at the beginning of the LALF part of B. Subtilis there was a throwing out signal and we expected death mostly here.</p>
+
-
<p><strong>Plate D2);</strong> At this plate we applied 100 ul of supernatant of B: subtilis not producing LALF protein and not having antibiotic resistance over the fresh spread of E. Coli as a single drop.</p>
+
-
<p><strong>Plate D3);</strong> At this plate we applied 100 ul of supernatant of B: subtilis not producing LALF protein and but that has antibiotic resistance over the fresh spread of E. Coli as a single drop.</p>

-
<p>We  ensured the formation of Bacillus Subtilis biofilm with LALF(plateA1) and without LALF(plateA2).Then we put onto E.coli with RFP this biofilms.Obviously we observed E.coli with RFP can’t grow on LALF biofilm.</p>

<p><strong><span id="2"><h1>DISC EXPERIMENT 2</h1></span></strong></p>
+
-
<p>We have prevented E.coli growth in our experiment. We took antibiotic disks which are used in hospitals.</p>
+
-
<p>We put antibiotic disks onto spreads of E.coli which produces RFP protein and has the chloramphenicol resistance. Then, we added different amounts of supernatant.</p>
+
-
<p>We used supernatant with LALF and without LALF of B.subtilis. We centrifuged LB broth culture which was incubated for 12 hours at 37°C at 7000 rpm for 5 minutes. It is filtered with 0,2 filter, afterwards.</p>
+
-
<p><img src="https://static.igem.org/mediawiki/2011/f/f9/IMG_0331.JPG"></p>
+
-
<p>E.coli with RFP was spread on both of two plates. 40ul, 80ul, 120ul and 160ul supernatant of B.subtilis which do not include LALF protein was added into left plate. Then 40ul, 80ul, 120ul and 160 supernatant of B.subtilis which include LALF protein was added into right plate .We got results which support other experiments.</p>

+
-
<p>Supernatants with and without LALF protein was put onto 50 ul spread of E.coli with RFP  in declared amount at the picture  .Again we got results which is overlapped other our experiments.</p>
+
-
<p>The reason of making this experiment with antibiotic and without antibiotic plate was if antibiotic effects LALF or not?</p>

-
<p><strong><h1><span id"3">Sterilization period of Supernatant</span></h1></strong></p>
+
-
<p>We have deduced that supernatant of B.subtilis that produces LALF sterilize the surfaces that LALF had applied on. Thus, we wanted to test how long this sterilization exists. To do this, supernatants with and without LALF waited in +4 ⁰C for 24 and 36 hours. Then, we tested their ability to sterilize.</p>
+
-
<p><img src="https://2011.igem.org/File:Mustafa1.JPG"></p>
+
-
<p>Equal amount of E.coli with RFP sequence were spread into the fresh plates Then, 100 ul supernatant with and without was added on plates. Note that no colony grew on where supernatant that contents LALF was added after both 24 and 36 hours. (the plates on the right)</p>
+
-
<p><img src="https://static.igem.org/mediawiki/2011/1/10/Mustafa2.JPG"></p>
+
-
<p>To understand better how much effective our protein is, we measured the diameter of the no growth zone. In 24 hour waited plate, diameter was 2,5 cm; on the other hand, it was measured 1,7 cm in 36 hour waited plate.</p>

<h1><strong><span id="4">THE SUICIDE EXPERIMENT OF E. COLI</span></strong></h1>
+
-
<p><em>Our K541545 part contains IPTG promoter and the gene part of LALF protein on a backbone which has resistance to chloramphenicol. We transported this part to E. coli for testing whether E. coli would kill itself or not.</em></p>
+
-
<p><strong>Experiments of plates with and without IPTG<em> </em></strong></p>
+
-
<p>Plate A1: We streaked E coli culture which has K541545 on this plate and the plate includes IPTG and Chloramphenicol.</p>
+
-
<p>Plate A2: We streaked E coli culture which has K541545 on this plate and the plate includes just Chloramphenicol.</p>
+
-
<p>Plate B1: This plate does not have IPTG and we streaked E.coli culture which does not have IPTG promoter.</p>
+
-
<p>PlateB2: This plate has IPTG and we streaked E coli culture which has IPTG promoter.</p>
+
-
<p>We prepared the B1 and B2 plates for testing toxic effect of IPTG. Because we wanted to be sure that the only factor affecting growth of E coli is LALF protein.</p>

<p><strong><span id="5"><h1>THE EFFECT OF FENTON REAGENT SOLUTION ON THE BIOFILM</h1></span></strong></p>
+
-
<p>Fenton Reagent solution is a solution that can kill the B. Subtilis spors and bacteria. It kills the spors by oxidizing with its Cu ions.</p>
+
-
<p>We prepared this solution in two ways one with the hydrogen peroxide (OFR) according to the literature and the other with distilized water (DFR).  In our experiments we learned which of these two solutions is more effective on E. Coli, B. Subtilis or the the spores of B. Subtilis and degree of its effectiveness.</p>
+
-
<p>The aim of this experiment is seeing the effects of the fenton reagen solution on the B. Subtilis and E. Coli on the biofilms.</p>
+
-
<p>We prepared Corn Strach Lb Agar for a more qualified biofilm. In order to understand the death in the plates we added a small amount to the liquid culture.</p>
+
-
<p>Plate 1: On this plate OFR is added on the B. Subtilis biofilm</p>
+
-
<p>Plate 2: We formed another B. Subtilis biofilm and added same amount of DFR on it.</p>
+
-
<p>Plate 3: On this contrivance one drop of E. Coli with RFP on the B. Subtilis biofilm and added same amount of DFR on it</p>
+
-
<p>Plate 4: On this contrivance one drop of E. Coli with RFP on the B. Subtilis biofilm and added same amount of OFR on it</p>
+
-
<p>Plate 5: this plate prepared as a control group of 3<sup>rd</sup> and 4<sup>th</sup> plates. On this contrivance one drop of E. Coli with RFP on the B. Subtilis biofilm but any kind of fenton reagent solutions didn’t add on it.</p>
+
-
<p>RESULT: After adding the FR solutions on all of plates, we measured their OD values in the end of this experiment we measured again and saw that the 1<sup>st</sup>, 2<sup>nd</sup>, 3<sup>rd</sup>, 4<sup>th</sup> plates OD values didn’t change. But the the OD value of 5<sup>th</sup> plate increased. 5<sup>th</sup> plate is the control group.</p>

<p><strong><span id="6"></span></strong></p><h1><strong>The Difference between Colonies Containing and Not Containing Gene Parts of Reflectin Protein</strong></h1><p></p>
+
-
<p>We transfered the plasmid which includes the gene part of reflectin protein (j04450 shuttle, j04500 backbone, and 1006) to E. Coli and we saw that there is a difference between reflectin including colonies and the colonies which does not include reflectin protein.</p>
+
-
<p>We saw that the plate which does not include reflectin protein is normally transparent. But the other plate which includes reflectin protein seemed white. And this is showing us that our plasmid is working and the protein is produced by E. coli.<br>
+
-
Figure-1: the difference of colonies is showing clearly, the colonies at the right side are seemed white and the colonies at the left side are seemed transparent.</p>
+
-
<p><img src="https://static.igem.org/mediawiki/igem.org/3/34/Aaa1.png"></p>
+
-
<p><img src="https://static.igem.org/mediawiki/igem.org/1/14/Aaa2.png"></p>
+
-
<p>Additionally, the colonies are looked into by microscope. The colony which is including reflectin has some transparent points. But the control group hasn’t these points. We are thinking that because of reflectin protein there are the points in these colonies.</p>
+
-
<p>&nbsp;</p>
+
-
<p><img src="https://static.igem.org/mediawiki/igem.org/0/09/Aaa3.png"><br><img src="https://static.igem.org/mediawiki/igem.org/9/9a/Aaa4.png"></p>
+
-
<p>Figure-4: Image of the colonies which are include reflectin protein by microscope  it’s clearly showing that the transparent points in the colonies</p>
+
-
<p>&nbsp;</p>
+
-
<p>Figure-6: Image of the control group which is not including the 1006 gene part and reflectin protein and it can clearly showing the difference from the colonies which include reflectin protein. There aren’t the transparent points here.</p>
+
-
<p><img src="https://static.igem.org/mediawiki/igem.org/0/0f/Aaa5.png"></p>
+
-
<p>Consequently, it’s confirmed that the 1006 gene part is producing the reflectin protein</p>

<h3><strong><span id="8"><h1>Experiment  of liquid culture</h1></span></strong></h3><br>
+
-
&nbsp;&nbsp;&nbsp;We wanted to see the effects of supernatant of B.subtilis which produces LALF  in order to stop  e.coli with RFP growth in liquid culture.<br>
+
-
&nbsp;&nbsp;&nbsp;We put 8 ml LB broth in falcons.<br>
+
-
&nbsp;&nbsp;&nbsp;We planned 3 control groups.These are:
+
-
<ul>
+
-
<li>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Control group 1:Includes only 5ul  e.coli which waited for  12 hours in 37⁰C. These can synthesize RFP.</li>
+
-
<li>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Control group 2:Includes only 5 ul b.subtilis which produces LALF. They waited for 12 hours in 37⁰C.</li>
+
-
<li>&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;Control group 3:Includes only 5ul b.subtilis which do not produce LALF. They waited for 12 hours in 37⁰C.</li>
+
-
</ul>
+
-
&nbsp;&nbsp;&nbsp;First of all, we put 5ul e.coli which has RFP into 8 falcons as experimental groups. We waited experimental falcons for 12 hours in 37⁰C . Then, we added 1ul,10ul,100ul and 1000ul liquid culture with LALF and liquid culture without LALF. After this,  we incubated them in 37⁰C and measured their OD value 2-4-8-12 hours later in 405 nm. Their results are as below:<br>

Charactarization

CHARACTERIZATION

Before starting assays; we needed to be sure that our genes had been cloned correctly. In order to use our parts in our experiments, we confirmed our parts via electrophoresis. Following parts are fully confirmed:

Subparts

Parts

BBa_K541501

BBa_K541515

BBa_K541502

BBa_K541545

BBa_K541503

BBa_K541596

BBa_K541504

BBa_K541915

BBa_K541505

BBa_K541800

BBa_K541506

BBa_K541516

 

BBa_K541526

 

BBa_K541546

After electrophoresis results; we furthermore performed sequencing and imaging tests to characterize our BioBricks. For BBa_541505 and BBa_541506; we added a GFP sequence and transformated into E.coli. This has characterized our main proteins. cDNA sequencing for these parts was also done successfully.
In addition, BBa_541800 is transformated into B.subtilis and successfully imaged red that shows RFP region and therefore plasmid backbone works properly.
We characterized BBa_K541545, BBa_K541515 and BBa_K541915 via sequencing.
