Online monitored characterization of Phocaeicola vulgatus for organic acid production using anaerobic microtiter plate cultivations

open access: yesBiotechnology Progress, EarlyView.
Abstract Phocaeicola vulgatus (formerly Bacteroides vulgatus), an anaerobic gut bacterium, produces several organic acids. Research on P. vulgatus is still in its infancy. However, a detailed understanding of P. vulgatus growth and metabolism is essential for its assessment as an organic acid producer.

Process intensification of the baculovirus expression vector system using a perfusion process with a low multiplicity of infection at high cell concentrations

open access: yesBiotechnology Progress, EarlyView.
Abstract The emergence of new viruses and the spread of existing pathogens necessitate efficient vaccine production methods. The baculovirus expression vector system (BEVS) is an efficient and scalable system for subunit and virus‐like particle vaccine production and gene therapy vectors.

Improving outcomes in intensified processing via optimization of the cell line development workflow

open access: yesBiotechnology Progress, EarlyView.
Abstract As the industry continues to explore the benefits of continuous and intensified manufacturing, it is important to assure that the cell line development (CLD) workflows in practice today are well suited to generate clones that meet the unique challenges associated with these processes. Most cell lines used in intensified processes are currently

Iterative hybrid model based optimization of rAAV production

open access: yesBiotechnology Progress, EarlyView.
Abstract Changes in serotype or genetic payload of recombinant adeno associated virus (rAAVs) gene therapies require adapting the transfection conditions of the upstream HEK293 cultivations. This study adopts an iterative model‐based experiment design approach, where increasing data availability is leveraged to evolve models of different complexity ...

N‐1 semi‐continuous transient perfusion in shake flask for ultra‐high density seeding of CHO cell cultures in benchtop bioreactors

open access: yesBiotechnology Progress, EarlyView.
Abstract One strategy to enhance the production of biological therapeutics is using transient perfusion in the preculture (N‐1 stage) to seed the production culture (N stage) at ultra‐high cell densities (>10 x 106 viable cells/mL). This very high seeding density improves cell culture performance by shortening the timeline and/or achieving higher final

Continuous purification of a parvovirus using two aqueous two‐phase extraction steps

open access: yesBiotechnology Progress, EarlyView.
Abstract Aqueous two‐phase systems (ATPS) are a liquid–liquid extraction method that offers low‐cost, continuous‐adaptable virus purification. A two‐step ATPS using polyethylene glycol (PEG) and sodium citrate that recovered 66% of infectious porcine parvovirus with 2.0 logs of protein removal and 1.0 logs of DNA removal in batch has now been run ...
