Study on Scale-Up of Anaerobic Fermentation Mixing with Different Solid Content

نویسندگان

چکیده

The scale-up technology of anaerobic fermentation stirring equipment is worthy attention. Computational fluid dynamics (CFD) simulations were used to study the mixing under different solid content conditions. applicability criteria was analyzed by investigating relative parameters, such as blade tip speed and Reynolds number. On this basis, index optimized verified. results revealed five common When less than 5%, tank should be scaled up according same Weber between 5% 10%, speed; it especially suitable for other conditions that limit shear rate. Scaling number not recommended due poor effect. x reached 0.75, there no need further reduce it. For systems, indices selected 15% 1.1, 1, respectively.

Lab-Scale Production of Bacillus atrophaeus’ Spores by Solid State Fermentation in Different Types of Bioreactors

Studies were conducted to evaluate Bacillus atrophaeus spores’ production by solid-state fermentation (SSF) using sugarcane bagasse as support and soybean molasses as substrate at lab-scale in column bioreactors (forced aeration), plastic bags and Erlenmeyer flasks (aeration by diffusion). Different moisture contents (84%, 86% and 88%; 89%, 91% and 93%) and aeration rates (30mL/min, 45mL/min, 6...
