<h3>Controlled chemistry plant</h3>
 
-
<p>As we know, biofilms are always used for chemical transformations in biorefineries. To utilize biofilms more efficiently, we need to control them and make them replaced. Here we expect to use dispersal proteins along with population-driven quorum-sensing switches to accomplish this goal.</p>
 
-
<p>We found some paper on related studies. In one of them, the researchers form an initial colonizer biofilm in a microfluidic device, introduce a second cell type called disperser into this existing biofilm, form arobust dual-specied biofilm and displace the initial colonizer biofilm with an extraceller signal from the disperser cells. They also remove the disperser biofilm with a chemically induced switch, and the consortial population could tune. The sketch followed show the mechanism of it. </p>

<p>The two E.coli cell types communicate by using the LasI/LasR QS module of P.aeruginosa. In the disperser cell, the LasI protein(autoinducer synthase) is constitutively produces and synthesizes the QS signal 3oC12HSL.  3oC12HSL freely diffuses into the initial colonizer cell and makes a complex with LasR(LuxR family transcriptional regulator), and the 3oC12HSL+LasR complex induces biofilm dispersal protein BdcAE50Q by activating the lasI promoter. BdcAE50Q disperses biofilms by binding cyclic diguanylate. The biofilm dispersal protein Hha13D6 in the disperser cell is induced upon adding IPTG. Hha13D6 disperses biofilms by activating proteases.</p>

-
<p>We want to develop the system and found a system contains three E.coli cell types, in which the first one can be replaced by the second one, the second one can be replaced by the third one and the third one can be replaced when added some chemical signals. Thus, this kind of controlled chemistry plant can be applied to a three-step chemical reaction and each kind of cells will finish one of them in sequence, just as follows.</p>

<h3>Synchronized bacterial clock</h3>
 
-
<p>Human orchestrate their activities in different places because of their synchronizing clocks. Isn't it cool if bacteria can coordinate their molecular timepieces in the same way as we human do?</p>
 
-
<p>We found that Hasty and colleagues have constructed a network of genes and proteins in E.coli that acts as a molecular clock and can be synchronized across a population of the bacteria. The mechanism can be described briefly as follows.</p>

<p>A promoter(PluxI)drives the production of LuxI, an enzyme that synthesizes the quorumsensing signal acyl-homoserine lactone (AHL). Another PluxI control ths the production of AiiA, a protein that catalyses the degradation of AHL, and a third PluxI triggers the synthesis of a variant of green fluorescent protein called yemGFP. An AHL receptor, LuxR, is constitutively expressed. The authors combined these components to form an autoinducng circuit (AHL activates LuxR, and the AHL-LuxR complex induces PluxI-driven luxI transcription and yemGFP production) with a time-delayed negative feedback loop (the AHL-LuxR complex induces PluxI-driven production of AiiA, which degrades AHL). The result was a population of bacteria that produce synchronized pulses of fluorescence, coordinated by quorum sensing. </p>

<p>We expect to apply the network to medical field. Since the network can make an oscillation, it can be used to release medicine periodically. What is more, we wish to add another sensor in the network. The sensor can sense a signal which is released because of a certain disease, and thus the cells can sense the signal and start the oscillation which releases the medicine periodically. For instance, when a man hasdiabetes, the high density blood sugar will start an insulin-releasing oscillation.</p>

<h3>EPad</h3>
 
-
<p>Ipad is popular all over the world, but how about an Epad? Have you thought that there is a tablet whose screen is made up of E.coli and it can sense your touch to display different colors? </p>
 
-
<p>MscL is a kind of membrane protein of E.coli. They control the transportation of matter, but they are usually closed. When the balance between intracellular and extracellular is broken, or the cytomembrane senses some unusual mechanical force, they will open and let the pressure disappear. We hope to utilize the protein and found a network which can display fluorescence of different color according to the state of MscL. In this way, a pressure-sensing and -controlling screen made of E.coli can be built. </p>

<h3>Methane alarm</h3>
 
-
<p>The concentration of methane in the coal mine is an important indicator which affects the life safety of miners. There should be alarm when the concentration of methane is between 1.0-1.5percent in the coal mine under the Chinese law.
 
-
We aim to design a methane alarm for coal mine by methanotrophs, which consists of four parts: decomposition, sensor, signal tuner and output. Decomposition part takes in methane and conducts catalytic decomposition of methane to CO2 or assimilates methane as its own organic compounds. This function is the naturally exist in methanotrophs. Sensor senses the concentration of methane and produces activator A. As for signal tuner part, we plan to find a substance B which is sensitive to the concentration of activator A. Activator A and substance B combines to control the activity of substance C. Substance C acts as the switch of promoter--when the concentration of methane has been exceeded the alarm threshold, promoter will turn on. Output part will give the alarm by producing pigment of red lycopene when promoter is open. We plan to put methanotrophs on the miner lamp. When the bacteria produce pigment, the light through bacteria will turn out to be red.</p>

<h3>Silkworm</h3>
 
-
<p>Hangzhou is famous for silk. We wish to let engineered bacterial produce silk proteins, just like lovely silkworm. A machine which can make threadlike things with the proteins will be used to make silk.</p>

<h3>Radio-communication</h3>
 
-
<p>Synthetic biology always needs bacteria to sense an input signal and output another. It occurs to us that we can use two kinds of bacteria to accomplish the task. The first one kind of bacteria senses the input signal and then fluoresces, while the second one senses the fluorescence from a distance far away from the first one and then output the final signal. It do not need a straight contact between the two kinds of bacteria, seeming like a radio-communication.</p>

<h3>Plant doctor</h3>
 
-
<p>When the leaves of some kinds of plants are bitted by insects, the substance A in the juice of plants will react with the one B in the spit of the insects. As a consequence, a volatile matter is produced, which attract the natural enemy of the insect. We plan to engineer the bacteria, having a symbiosis with plants, with genes of the enzymes which catalyze the production of the substance A in the juice. The bacteria will make plant doctors.</p>

<h3>2012/8/13 Monday, August 13, 2012</h3>
 
-
<p>Yu Jianing and Yan came to Prof. Chen Xin for MD (molecular dynamics simulation, suggested by PKU iGem) modeling in RNA scaffold project. Prof. CHEN pointed out that it's so hard and costing for us green hand undergraduates to manipulate MD, which could be replaced by RNA prediction software and ODE modeling with matlab.</p>
 
-
 
-
<p>Zhang and Chen transform a group of D0, FA and FB with different combination.</p>
 
-
<p>LIU Xiao comes to carry out point mutation experiment to modify origin D0 in PCR method. He intended to build a library. However, we have only one month left, too short to finish the library.</p>
 
-
<p>Yan's fluorescent test with part K537009 is modestly successful. Most excitingly, Yan and Chen capture a love heart (or you can refer to it as a smiling smile) imaging by E.coli.</p>

<h3>2012/8/15 Wednesday, August 15, 2012</h3>
 
-
<p>Prof. SHAO Jianzhong is willing to let us use the Synergy hybrid reader in his lab.</p>
 
-
<p>Chen and Zhang test fluorescence of D0, FA,FB,FA+D0,FA+FB,FA+FB+D0 with IPTG concentration gradient but find out that the fluorescence intensity are nearly no difference comparing with scaffold and without scaffold surprisingly.</p>

<h3>2012/8/16 Thursday, August 16, 2012</h3>
 
-
<p>After senior fellow's advises, however, we still can't see the result in < Organization of Intracellular Reactions with Rationally Designed RNA assemblies>.</p>
 
-
 
-
<p>Yan tried the parts of Theophylline riboswitch with YFP Venus reporter and it worked.
 
-
(Though excite 515nm emit 528 mn is too close for Synergy hybrid reader to detect and we change it into 505nm and 535nm.)</p>
 
-
<p>You can see the fluorescence intensity increasing with Theophylline concentration.</p>
 
-
 
-
<p>All night talks and strange Sequencing results make us skeptical about the FAFB plasmids sent by French lab (which is crucial to our project). Maybe there's something wrong with our raw material.</p>
 
-
 
-
<h3>2012/8/17 Friday, August 17, 2012</h3>
 
-
<p>Today we faced mega-disaster that most of us thought the plasmids: FA & FB sent early August are not what we were asking for. Dr. Delebecque is so helpful and patient but he's away from his French lab now. He sent us an email providing a lot of information we need if we construct the plasmid on our own.
 
-
So we have to go back and start from the very beginning.
 
-
Chen, Zhang and Liu try to redesign the primers; Prof. Shao lent us the eGFP. Our advisor, Li Xin comes to discuss with us the technology of construct.</p>

<p>He makes a new RNA scaffold, Nucleic Acid Electrophoresis as follows. </p>
 
-
<p>First step:</p>
 
-
 
-
<p>Second step:</p>
 
-
 
-
<p>First step product is due in 50bp and second is due in 200bp.

<p>1. Zhang continues LIU Xiao's point mutation D0 library experiment. According to the instructions of DNA gel extraction kit, she recover enzyme-digested products product pETDuet-BB, put new D0 into it.</p>
 
-
<p>2. We receive part K411003 and plate it on Chloramphenicol plates, and incubate.</p>
 
-

<h3>2012/8/21 Tuesday, August 21, 2012</h3>
 
-
<p>1. K411003 (Taipei 2010) were adding a series of Theophylline. This experiment is used both for testing parts and fishing for the condition of our synthetic D0 from Genescript's future GFP experiment. </p>
 
-
<p>2. The Synergy hybrid reader data is good. You can see the fluorescence intensity increasing with Theophylline concentration.</p>

<h3>2012/8/22 Wednesday, August 22, 2012</h3>
 
-
<p>1. 00:39 in the morning, YU Jianing sends an e-mail to Yan from her hometown, attaching version 1 ODE modeling and some questions about biology meanings.</p>
 
-
<p>2. We start our major experiment: construct FA-2X-MS2 and FB-2X-PP7</p>
 
-
<p>2.1 Fragment</p>
 
-
<p>1. We PCR FA and FB from pEGFP. </p>
 
-
<p>2. We PCR MS2 from FAM( from Dr. Delebecque)</p>
 
-
<p>3. We PCR PP7 from FBP(from Dr. Delebecque )</p>
 
-
<p>Then use gel extraction kit to get these fragment.</p>
 
-
<p>2.2 Overlap PCR</p>
 
-
<p>First overlap PCR in our lab. We uses precisely designed primers to make FA and MS2 linked with 2X. So does FB and PP7.</p>
 
-
<p>3. Zhang goes on with LIU Xiao's point mutation and use Megaprimer PCR methods.</p>
 
-
 
-
<h3>2012/8/23 Thursday, August 23, 2012</h3>
 
-
<p>1. Yan PCR riboscaffold (synthesis by Genescript) and make it into Part.</p>
 
-
<p>2. Zhang continues mutation D0 and enzyme digest the fragment for PCR test.</p>
 
-
<p>3. LIU Huachun uses some parts form registry to construct a new EGFP for positive control.</p>
 
-
 
-
<h3>2012/8/24 Friday, August 24, 2012</h3>
 
-
<p>1. LIU reproduce pSB1C3</p>
 
-
<p>2. Yan continues to make part of riboscaffold.</p>
 
-
<p>3. Chen use Taq DNA Polymerase (ordinary) to put A onto FA-2X-MS2 and FB-2X-PP7 and link  it onto T vector.</p>
 
-
 
-
<h3>2012/8/25 Saturday, August 25, 2012</h3>
 
-
<p>1.  We extracted and amplified the mutation D0 library and then sent it to a sequencing facility</p>
 
-
<p>2.  LIU's pCDF-EGFP: transform into DH5&alpha; (It works pretty well.)</p>
 
-
<p>3.  Miniprep: Yan's last day's part riboscaffold</p>
 
-
 
-
<h3>2012/8/26 Sunday, August 26, 2012</h3>
 
-
<p>1.  Miniprep: pCDFDuet-EGFP and pColaDuet</p>
 
-
<p>2.  Part riboscaffold PCR: a little different from its original PCR from pETDuet Genescript.
 
-
So we should send sequencing for validation.</p>
 
-
 
-
<h2>Week 11 Recuperate</h2>
 
-
<h3>2012/8/27 Monday, August 27, 2012</h3>
 
-
<p>1.  Chen did the overlap PCR and construct FB-2X-PP7 (approximately 630 bp). It seems correct in the agarose gel electrophoresis. (1000 marker on the left and 5000 marker on the right)</p>
 
-
<p>2.  Yan and Chen PCR MS2 from plasmids Dr. Delebecque sent us respectively.
 
-
Yan uses 57.5 Degrees Celsius as melting temperature and Chen uses 58.5 and 63.5.
 
-
But the electrophoretic bands seem incorrect.
 
-
(Next day we find angrily that the primer the company synthesized is wrong!)</p>
 
-
 
-
<h3>2012/8/28 Tuesday, August 28, 2012</h3>
 
-
<p>1.  LIU uses gel extraction to get last day Chen's MS2 and carry on overlap PCR to make FA-2X-MS2.</p>
 
-
<p>2.  Chen transforms FB-2X-PP7 (T vector) into Top 10.</p>
 
-
<p>3.  Repeated tests: Yan does the same as LIU and sets annealing temperature 59Degrees Celsius and 61Degrees Celsius. </p>

<h3>2012/8/29 Wednesday, August 29, 2012</h3>
 
-
<p>4.  Teacher Hu Yuhua from Edinburgh University interviews us concerning team collaboration. She offers that if we have oral English barriers we could come to her.</p>
 
-
<p>5.  LIU makes competent cell of DH10&beta;</p>
 
-
 
-
<h3>2012/8/30 Thursday, August 30, 2012</h3>
 
-
<p>All of us attend short semester and did nothing about igem today.</p>
 
-
 
-
<h3>2012/8/31 Friday, August 31, 2012</h3>
 
-
<p>1.  Sequencing result shows that FB-2X-PP7 we have constructed was correct in T vector.
 
-
So LIU prepare some for Miniprep and glycerol freeze store.</p>
 
-
<p>2.  Enzyme digestion and ligation: make FB-2X-PP7 from T vector into pColaDuet and transform it in DH5&alpha;.</p>
