− | In the process of oil recovering by water injection method, it will form large water channels in the bottom. <br/><br/>
| + | |
− | Water mainly flows through these channels, which stops brushing the oil hidden in the minor channel branches in soil, so that the remaining oil will be trapped into the branches. </br>
| + | |
− | Our project is aiming to engineer Enterobacter sp. <i>FY-07</i> (which is separated from oilfield produced water and able to produce cellulose naturally), so as to controllably produce rhamnolipid and cellulose.</br>
| + | |
− | Rhamnolipid is a biosurfactant with the ability of emulsifying oil, so the oil can be easily washed out.
| + | |
− | Cellulose can clog large water channels, helping water enter into the gaps of soil and wash out the oil within them.</br><br/>
| + | |
− | Our project is aimed at improving oil recovery rate in the oil harvesting process using this kind of bacteria.

| + | |
− | | + | |
− | 1. We have cloned rhamnolipid synthesis gene (<i>rhIABC</i>) in Pseudomonas aeruginosa, and transformed it into <i>Escherichia coli BL21</i> and successfully achieved the expression of <i>rhIABC</i> in <i>E.coli BL21</i>.
| + | |
− | <br/><br/>
| + | |
− | 2. We have transformed rhIABC into <i>FY-07</i> and successfully fulfilled the co-production of rhamnolipid and cellulose.
| + | |
− | <br/><br/>
| + | |
− | 3. Based on <i>E.coli</i> fimbriae control system (<i>E.coli</i> fimbriae (Fim) phase variation system), we have finished the switch design, to whose both ends GFP and RFP have been linked. This modified switch has been transformed into <i>BL21</i> and proved to be feasible.

− | <div class="sub-header">FUTURE PLAN</div>
| + | |
− | 1. Finish the construction of plasmid.
| + | |
− | <br/><br/>
| + | |
− | 2. Introduce molecular switch and rhamnolipid synthase into <i>BscA</i> gene knock out <i>FY-07</i> strain.
| + | |
− | <br/><br/>
| + | |
− | 3. Achieve controllable expression of rhamnolipid and cellulose in <i>FY-07</i> strain.
| + | |
− | <br/><br/>
| + | |
− | 4. Introduce suicide system and ensure the controllability.

− | 1. We expect to communicate with the practitioners in oil industry so as to know more about applying petroleum microorganisms into oil production. Please contact us if you are a practitioner in oil industry who has some knowledge in this field.
| + | |
− | <br/><br/>
| + | |
− | 2. We are looking for a suitable suicide system so that the bacteria will not survive in the environment for a long time. Please contact us if you have some recommendations.
| + | |
− | <br/><br/>
| + | |
− | 3. Please do not hesitate to contact us if you are interested in our project. We are looking forward to communicating with you!
