| |
| - | <p>1.For M9 medium using oleic acid as sole carbon source, various amount of oleic acid was first emulsified 1:1 with 10% Triton X-100. M9 medium was then slowly added with constant vortex. M9 medium with high concentration of oleic acid was diluted by M9 medium with triton to form various concentrations；</p>

| |
| - | <p>To test metabolism of long fatty acids, we used oleic acid as sole carbon source in mediums, and used cupric-soap reaction to determinate oleic acid concentration preliminarily. </p>
| |
| - | <p>Modified M9 minimal medium with emulsified oleic acid as sole carbon</p>
| |
| - | <p> Minimal medium was the same with that in Materials and methods for PfadR </p>
| |
| - | <p>What's Important:</p>
| |
| - | <p>Slowly pour M9 minimal medium into mixture of oleic acid and Triton X-100 to get more homogeneous solution.</p>
| |
| - | <p>Analysis the concentration of the oleic acid in the medium by cupric-acetate method</p>
| |
| - | <p>1.Collect 5 ml medium which has been used to cultivate bacteria. Then centrifuge the medium at 3000rpm for 10 min to separate bacteria and medium;</p>
| |
| - | <p> 2.Decant 3ml supernatant liquid into a 10ml EP. Add 3ml acetone to the liquid, 1ml at a time, shaking 10-20 times before adding another 1 ml in order to avoid the effect of the ions of the liquid during the extraction progress;</p>
| |
| - | <p> 3.Add 3 ml isooctane once ,shaking for at least 90s, stand for 2min or longer until layering completely;</p>
| |
| - | <p>4.Collect 3 ml clear isooctane in a 5 ml EP, Add 800l cupric-acetate (5% m/v, adjust pH to 6.8 with pyridine), Shaking for 90 seconds, stand for 2min or longer until layering completely;</p>
| |
| - | <p>5.Detect OD of organic phase in a spectrometry at 715nm.</p>

| |
| - | <p>We add 1.6ml, 3.2ml, 4.8ml, 6.4ml, 9.6ml, 11.2ml oleic acid into 3ml M9 medium to generate a gradient. The absorbency is measured as described in the protocol.</p>

| |
| - | <p>We slightly modified the methods provided by Kwon and Rhee, 1986, adding the extraction step, for it is dispensable when bacteria are in the medium. However, the standard curve is still very close to the paper’s, which proves that plausible and accurate</p>

| |
| - | <p>About E.coslim by Kuanwei Sheng</p>
| |
| - | <p>In order to help people lose weight, besides our three devices, we also have come up with many other creative ways. </p>
| |
| - |
| |
| - |
| |
| - | <p>Ⅰ.Short chain peptides synthesis</p>
| |
| - | <p>Recent researches have indicated that some short chain peptides in intestine have effect on inhibiting appetites, therefore decrease the food intake. We thus formed the idea that we could synthesis a DNA chain that encodes those short peptides.</p>
| |
| - |
| |
| - | <p>Ⅱ.Biosynthesis of L-carnitine </p>
| |
| - | <p>L-carnitine is a molecule that facilitates the progress of transporting fatty acids into mitochondria where these fatty acids will be disintegrated. We once considered use L-carnitine to help the host metabolize fatty acid better. However, the biosynthesis of L-carnitine has too many derivatives or the pathway is patented by others.</p>
| |
| - |
| |
| - | <p>Ⅲ.Xylose isomerase</p>
| |
| - | <p>Xylose is a prebiotics that can hardly be absorbed by human. We consulted many papers and find that glucose can be converted into xylose by xylose isomerase. Therefore, we thought maybe we could lower the glucose available in intestine by expressing xylose isomerase. However, this process is shown to be reversible latter. Mutated the sequence of the protein may generate high converting rate, yet it is too laborious and risky for a short time project.</p>

| - | <p>Tackle Water bloom by Tong Wang and Kuanwei Sheng</p>
| |
| - | <p>Since the detrimental effects caused by cyanobacteria to the environment such as making water carcinogenic have become a serve global problem, we therefore tried to employ E.coli as an expression system to eliminate these detrimental effects. When we first took over this project, we thought about limiting the growth of cyanobacteria. Along with the process we got to read a large amount of relevant papers about cyanobacteria, we found that not only the main detrimental effects caused by cyanobacteria is attributed to its product which is a cyclic peptide called microcystin, but also microcystin can regulate the population density. Then we came to realize the importance of microcystin and began to search information about it. Through over this process, we discovered a gene cluster which is responsible for the microcystin degradation pathway. It encodes four enzymes——MlrA、MlrB、MlrC and MlrD. Also, we found that some non-toxic cyclic peptides produced by cyanobacteria such as Anabaenopeptin B and Anabaenopeptin F can induce lysis of cyanobacteria. The latter finding can be utilized as an effective cell population density control mechanism. Thus we thought about constructing two independent systems to eliminate cyanobacteria, one about inducing lysis of cyanobacteria and the other about degrading microcystin. Finally we gave up this project because of the reasons that these gene clusters are too large to be expressed in E.coli and that E.coli cannot survive in the sea, however, we still feel proud of these fancy ideas.</p>

| - | <p>Desalination of sea water by Kuanwei Sheng</p>
| |
| - | <p>We came up with the thought that engineering bacteria can intake ions like Na+, cl-, Mg2+ and etc. under special stimulus. Also, under another certain stimulus, the bacteria can export those salts out of cells for reuse. Therefore, we can use these bacteria to desalinize sea water and extract the salt the same time. However, there is no such ion channel that can meet our needs.</p>

| - | <p>Sense the earthquake By Min Ye</p>
| |
| - | We once tried to find proteins that can sense vibration and construct a pathway to report that vibration. However, we are not able to find the protein that can meet our needs.</p>

| - | <p>Auto plasmid preps By Kuanwei Sheng</p>
| |
| - | <p>We thought about constructing a synthetic protein that combines zinc finger protein which can recognize the specific sequence of DNA and signal peptide that can make proteins be exported out of the bacteria by secretion pathway. Therefore, it is possible that plasmid can be exported out the cells together with the zinc finger protein.</p>

| - | <p>Outer Membrane Vesicle (OMV) to treat cancer By Kuanwei Sheng</p>
| |
| - | <p>We thought to use Outer Membrane Vesicle (OMV) to treat cancer. Specifically, we thought about localizing antibody that can recognize certain cancer on the surface of OMVs via signal peptides. Also, we thought we may localize cell division inhibitor protein or protein that lead to cell death inside the OMVs. Therefore, we hoped that the OMV excreted by the bacteria can recognize and kill cancer cells.</p>
