Introduction Bio-pharmaceutical industries face an increasing demand to accelerate process development and reduce costs. This challenge requires high throughput tools to replace the traditional combination of shake flasks and small-scale stirred tank bioreactors. A conventional and widely used process development tool is the stirred tank reactor (STR) ranging from approximately 1L to 10L in wor...

A novel milliliter-scale stirred tank bioreactor was developed for the cultivation of mycelium forming microorganisms on a 10 milliliter-scale. A newly designed one-sided paddle impeller is driven magnetically and rotates freely on an axis in an unbaffled reaction vessel made of polystyrene. A rotating lamella is formed which spreads out along the reactor wall. Thus an enhanced surface-to-volum...

In this paper, the modeling of a dynamic chemical engineering process is presented in a highly understandable way using a unique combination of the simplified fundamental theory and direct hands-on computer simulation. The main aim is to use them for analysis, optimise and adaptive control of behavior of dynamical system, especially of a given chemical reactor. A non-linear mathematical model i...

Different concentrations of oily waste were added in a discontinuous mode and recurrently to anaerobic continuous stirred tank reactors fed with cow manure and food waste. Four continuous stirred tank reactors were run in parallel. A control reactor (R1) received no additional oil and R2, R3 and R4 received increasing concentrations of oil in two different experimental approaches. First, the li...
