peer reviewed / Culture medium heterogeneity is inherent in industrial bioreactors. The loss of mixing efficiency in a large-scale bioreactor yields to the formation of concentration gradients. Consequently, cells face oscillatory culture conditions that may deeply affect their metabolism. Herein, cell response to transient perturbations, namely hi...

Extracellular vesicles (EVs) are widely implicated as novel diagnostic and therapeutic modalities for a wide range of diseases. Thus, optimization of EV biomanufacturing is of high interest. In the course of developing parameters for a human embryonic kidney cells (HEK293T) EV production platform, we examined the combinatorial effects of cell cultu...

Recovery of the energy contained in biogas will be essential in coming years to reduce greenhouse gas emissions and our current dependence on fossil fuels. The elimination of H2S is a priority to avoid equipment corrosion, poisoning of catalytic systems and SO2 emissions in combustion engines. This review describes the advances made in this technol...
PurposeThere is a growing interest in extracellular vesicles (EVs) for ocular applications as therapeutics, biomarkers, and drug delivery vehicles. EVs secreted from mesenchymal stem cells (MSCs) have shown to provide therapeutic benefits in ocular conditions. However, very little is known about the properties of bioreactor cultured-3D human retina...
Fermentation processes are considered to be essential to decrease our reliance on fossil fuel based products. However, the scale-up from lab-scale to industrial-scale has proven to be difficult. Computational Fluid Dynamics (CFD) has the potential to be a tool to optimize the scale-up and to help engineers understand the relevant hydrodynamics insi...

The electrochemically driven cytochrome P450 reactions have great promise as drug sensing device, new drug searching tool and bioreactor with broad synthetic application. In the present work, we proposed approaches for the increasing the efficiency of cytochrome P450 3A4 electrocatalysis, based on fine regulation and reproduction of nature hemeprot...

The growth-associated metabolites are produced during the exponential phase; however, this phase terminates due to substrate depletion or product inhibition. In the present study, a semicontinuous mode with a fill-and-draw strategy was applied to extend the exponential phase of the biosurfactant production to overcome the product inhibition and in ...

Cardiac fibrosis is a key contributor to the onset and progression of heart failure and occurs from extracellular matrix accumulation via activated cardiac fibroblasts. Cardiac fibroblasts activate in response to mechanical stress and have been studied in the past by applying forces and deformations to three-dimensional, cell-seeded gels and tissue...
Práce se zavývá návrhem parametrického fasádního systému za užití bioreaktorů. Byla zmapováná stávající problematika fasádních systémů a navržen nový typ panelu. Důraz je kladen na vytvoření systému, který je možno pomocí parametrizace aplikovat na složité povrchy při zachování funkčnosti, architektonických kvalit a možnosti prefabrikace fasády. .K...
