Multiphase contacting between gas, solid and liquid phases is effected using a novel apparatus comprising a cylindrical vessel, a draft tube, a conical bottom and a gas-sparger system. Mild and uniform mixing is achieved within the novel apparatus while stagnant zones and zones of high shear within the vessel are eliminated. Gas-liquid mass transfer is achieved at rates comparable to conventional high-shear mechanically-stirred devices while the efficiency of liquid mixing in the vessel is better than conventional low-shear pneumatically-stirred devices. The apparatus is preferably used in fermentation processes.

Fermentation of a substrate by microorganisms capable of utilizing the substrate for growth is improved by conveying a fermentation medium including the substrate and microoganisms through a hollow tube with the assistance of an internal wall-scraper.

Fermentation processes using scraped tubular fermentor

The presence of small dissolved quantities of carboxypolymethylenes in culture media producing cellulase or penicillin enhances the fermentation parameters.

Fermentation processes for making penicillin and cellulase

Fermentation parameters are improved by the addition of certain polymers to the fermentation broth. Small quantities of carboxypolymethylene in Aspergillus niger cultures are particularly effective.
