In humans, caspase-5 is an LPS sensor that can induce gasdermin D cleavage and pyroptosis. Here, the authors show that zebrafish caspy2 is a functional homolog as it also senses cytosolic LPS to activate the noncanonical inflammasome and to protect ...

Dynamic response of Aspergillus niger to single pulses of glucose with high and low concentrations
Microorganisms generally encounter a fluctuating environment in their natural habitat and similar conditions also happen in large-scale bioreactors. In this work, the dynamic response of intracellular and extracellular metabolites of Aspergillus niger ...

Operation of a Benchtop Bioreactor [PDF]
Fermentation systems are used to provide an optimal growth environment for many different types of cell cultures. The ability afforded by fermentors to carefully control temperature, pH, and dissolved oxygen concentrations in particular makes them essential to efficient large scale growth and expression of fermentation products. This video will briefly

FLOCCULATION BIOREACTORS [PDF]
One of the main goals of bioprocess engineering is to increase the productivity of biotechnological processes and a vigorous progress has been observed in that field over the last decades. Fermentation based processes are not an exception and, in order to achieve those objectives, techniques such as the use of high cell density systems have been ...

Plant Bioreactors for Pharmaceuticals [PDF]
Plant bioreactors are attractive expression systems for economic production of pharmaceuticals. Various plant expression systems or platforms have been tested with certain degrees of success over the past years. However, further development and improvement are needed for more effective plant bioreactors.
