Technobiological Pathways for High‐CO₂ Capture Using Micro‐/Macroalgae: Genetic Engineering, Process Automation, and Value‐Added Bioproducts

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

Enhancing CHO cell recombinant protein production using a perfusion‐directed host evolution approach

Biotechnology Progress, EarlyView.
Abstract Clonally derived cell lines generated from Chinese hamster ovary (CHO) cells encounter numerous stressors when cultured in high‐intensity perfusion bioreactors leading to poor process performance. To circumvent this, the ability of CHO cells to adapt to different culture environments was exploited. Here host cells were selected in the presence
