Single-use Technologies II: Bridging Polymer Science to Biotechnology Applications
Single-use bioreactors are well-established in production of biopharmaceuticals in mammalian expression systems. However, a similar technology breakthrough for microbial/yeast-based productions is still awaiting due to the unique requirements associated with such high-cell density cultivations, including high oxygen transfer capacity and efficient heat removal. Here, we present the single-use Xcellerex™ XDR-500 MO stirred-tank fermentor system specifically designed for microbial/yeast applications. The performance of the fermentor was evaluated using an E. coli fed-batch process producing a domain antibody (dAb) as a model system. The process was originally developed for a lab-scale conventional stainless steel system. This work describes the transposition and scale-up …
