Abstract
Abstract Apparatus is provided in the form of fermentation vessels which are provided with caps for substantially sealing the same against contamination, and with tube means for communicating between the inside and outside of the vessels. Stirring is effected by a magnetic element disposed within the vessels which is actuated by an external electromagnetic source.
