Abstract

A novel device has been designed for the evaluation of the effects of shear on microorganisms. The device consists of a combination of a coaxial cylinder plus cone and plate viscometers and enables cultures of both eukaryotic and prokaryotic microorganisms to be grown under fully defined and controlled fluid dynamic characteristics for serveral generations. In the preliminary tests performed a change in cell length was observed in Escherichia coli, and with Penicillium chrysogenum the septal length, hyphal diameter, and branching frequency all changes as shear was increased.
