Microorganisms are used in various fermentation processes for the production of biochemicals and food. These types of processes take place predominantly in mechanically agitated vessels. An important transport characteristic is the volumetric mass transfer coefficient kLa. Many correlations are available in the literature to estimate parameters in a gas-liquid system. However, three-phase systems are not sufficiently described. The experiments were carried out under laboratory conditions in a single-impeller mechanically agitated vessel with an internal diameter of 0.29 m. The solid phase was either cellulose, with two different particle sizes, or glass beads. An updated correlation is proposed that could be adopted in the design and scale-up of agitated devices operating in the presence of solid particles.
