Anticancer Activity of Rhamnolipids and Sophorolipids Biosurfactant Congeners

   Faculty of Health and Life Sciences

  Prof Ibrahim Banat, Dr Matthew Twigg  Monday, February 27, 2023  Competition Funded PhD Project (Students Worldwide)

About the Project

Rhamnolipids and sophorolipids are glycolipidic biosurfactants produced by bacterial and yeast cells, respectively and possess both hydrophobic and hydrophilic moieties. Studies in our laboratory have demonstrated that the molecular structure of specific glycolipid biosurfactants congeners are determine their biological activity against particular cancer cell lines whilst showing no significant effects on healthy cell of the same or similar source. To understand the effect acyl-sidechain length on anti-cancer activity, this project will utilise molecular biological tools to generate mono-rhamnolipid producing mutant from B. thailandensis and compare the actions of mono-rhamnolipids to those generated by P. aeruginosa strain using in vitro cell culture techniques.

Please note: Applications for more than one PhD studentship are welcome, however if you apply for more than one PhD project within Biomedical Sciences, your first application on the system will be deemed your first-choice preference and further applications will be ordered based on the sequential time of submission. If you are successfully shortlisted, you will be interviewed only on your first-choice application and ranked accordingly. Those ranked highest will be offered a PhD studentship. In the situation where you are ranked highly and your first-choice project is already allocated to someone who was ranked higher than you, you may be offered your 2nd or 3rd choice project depending on the availability of this project.
