In the search of anisotropic biocompatible liquid environments for bacterial motility studies

Abstract

Several experimental approaches are explored to introduce the E. coli bacteria in a liquid anisotropic host. Fonctionalization of the bacterial surface is experimented with 2 different molecules. The 5CB is first used as host and it is shown that, while the bacteria survive at short term in such an environment, they aggregate into colonies. Water solution of the cromolyn sodium salt is also explored with success and the time stability of corresponding sandwich-like structures is characterized.
