Purification of (recombinant) proteins for industrial and pharmaceutical use is accompanied by high costs and difficulties in the scale-up with the necessity of many purification steps. This thesis demonstrates the use of functionalized superparamagnetic iron oxide nanoparticles for the purification of recombinant histidine-tagged proteins directly from a growing culture of the gram-positive bacterium Bacillus megaterium. The separation was performed using commercial hand held magnets. Regenerability and reusability are shown in shake flask scale. Automation of the process is demonstrated at l...
