Bacillus subtilis grown in a "breathing" vessel without sparger aeration

Abstract

Here we present a "breathing" vessel consisting of expanded polytetrafluoroethylene, which allows gas exchange but no liquid permeation. The bacterial culture inside needs only agitation to promote air supply. Using this setup, a Bacillus subtilis cell factory for scyllo-inositol production grew to produce scyllo-inositol efficiently. The results indicate that our approach represents a sustainable "greener" approach for the cell factory.

Keywords: Bacillus subtilis; scyllo-inositol; expanded polytetrafluoroethylene; “breathing” vessel.
