✦ Synopsis

A mathematical model for single and multi step deep-jet bioreactors is presented. A stagewise approach based on macroscopic mechanistic model which divides the reactor into compartments with good quality of mixing and plug flow regions (macromixer), was used. For the mathematical representation of this model a system of differential equations, describing the concentration of tracer in structural elements based on mass balance, and the Runge-Kutta-Fehlberg numerical method of integration, was applied. The mixing time in a 300 dm 3 tank was determined by conductivity method with NaC1 as tracer.

A horizontal rotating tubular bioreactor (HRTB) was designed as a combination of a "thin-layer bioreactor" and a "biodisc" reactor whose interior was divided by O-ring shaped partition walls. For the investigation of mixing in K1 Wm-2 K 1 HRTB the temperature step method was applied. Temperature cha

## Abstract We present a mathematical model that describes heat and mass transfer during solid‐state fermentation (SSF) of __Aspergillus oryzae__ in a well‐mixed rotating drum bioreactor (RDB). In addition to the substrate bed and the headspace, the model recognises the bioreactor wall as a subsyst
