Effect of cell retention techniques in Komagataella phaffii lab‐scale continuous processes

open access: yesBiotechnology Progress, EarlyView.
Abstract Perfusion technologies play a growing role in the implementation of continuous processes for biotherapeutics production in mammalian‐based manufacturing. However, their application to alternative production hosts is limited. Cell retention systems are of key importance for the efficiency of perfusion bioreactors.

Hyperbranched Molecular Brush Membrane for Efficient and Antifouling Oil‐Water Emulsion Separation

open access: yesCleanMat, EarlyView.
This work develops a carboxyl‐terminated hyperbranched molecular brush‐modified membrane that exhibits superhydrophilicity, underwater superoleophobicity, and a strong negative charge. The membrane achieves high efficiency, superior antifouling performance, and stable separation of oil‐in‐water emulsions across a wide pH range.
