Abstract
Experimental results show that the mass transfer performance of unbaffled systems is mainly affected by specific power consumption. Among the stirrer geometries investigated a simple PBT was found to provide the most interesting oxygen transfer performance in the sub-critical regime, and can therefore be regarded as a particularly suitable stirrer for shear sensitive cultures. As regards the super-critical regime, unbaffled tanks are found to provide a performance comparable with that of the standard (baffled) bioreactors, hence resulting in a viable alternative also for fermentations involving robust cells.
