How we measure 'reads'
A 'read' is counted each time someone views a publication summary (such as the title, abstract, and list of authors), clicks on a figure, or views or downloads the full-text. Learn more

Manufacturing of biopharmaceuticals requires high quality water. Overall conditions for production of clean water vary across the globe due to availability and quality. We combined economic and ecological modeling to assess energy consumption of water production from tap to waste. We defined a metric, the WAter Related Impact of ENergy (WARIEN) to...
E. coli is an attractive host organism for strong recombinant protein expression. It expresses products either as soluble protein or as inclusion bodies (IB). IBs are insoluble, mostly inactive aggregates. However, recent progress enabled the efficient refolding back into their bioactive structure. Targeted IB production processes have been designe...
Primary recovery of intracellular products from E. coli requires cell disruption which leads to a massive release of process‐related impurities burdening subsequent downstream process (DSP) unit operations. Especially, DNA and endotoxins challenge purification operations due to their size and concentrations. Consequently, an early reduction in impu...
Background The methylotrophic yeast Pichia pastoris is a well-studied host organism for recombinant protein production, which is usually regulated either by a constitutive promoter (e.g. promoter of glyceraldehyde-3-phosphate dehydrogenase; PGAP) or an inducible promoter (e.g. promoter of alcohol oxidase 1; PAOX1). Both promoter systems have severa...
When the glycosylated plant enzyme horseradish peroxidase (HRP) is conjugated to specific antibodies, it presents a powerful tool for medical applications. The isolation and purification of this enzyme from plant is difficult and only gives low yields. However, HRP recombinantly produced in the yeast Pichia pastoris experiences hyperglycosylation w...
