Imperial iGEM 2014

Mass Production and Processing


Bacterial cellulose (BC) exhibits a multitude of different properties depending on the processing, growth conditions, functionalisation and strain used (Bismarck 2013) for production of the material. Acquiring large quantities of cellulose produced would allow testing of a broad variety of cellulose processing methods and functionalisation steps.

By mass producing cellulose this enables a better understanding of what material properties can be realistically produced during the short duration of iGEM. More importantly, it improves the likelihood of finding suitable processing candidates for the project’s aim of making a customisable ultrafiltration membrane, at the same time as allowing room for creativity and exploration of the remarkable properties of cellulose.
