Design Notes

It is worth informing that the Plac in the DNA feature's graph is a reverse promoter (activate LacI instead of activating rhlA, B, and C). The arrow on the feature is not accurate due to the reason that the image of the promoter won't appear in the reverse direction. Nevertheless, the DNA sequence is posted in the correct arrangement which Plac is responsible for activating LacI.

Our team aims to measure the amount of production of rhamnolipids by using HPLC-MS method. The specific quantification steps are shown below. Quantification using HPLC-MS 1. Add HCl into the liquid culture until the final pH is 2 2. Leave the solution overnight at 4° C 3. Extract the organic phase using an ethanol-chloroform solution in a ratio of 1:2. 4. HPLC-MS is performed using C18 column and acetonitrile as mobile phase.
