Mixed-Cultures and Alcoholic Fermentations [PDF]

arXiv, 2007
The population dynamics of mixed-culture and sequential-cultures in fruit-must fermentation is a very interesting problem from both the theoretical and technological stand point. By mixed-culture we refer to those fermentations in which more that one strain/species are present from the beginning of the process; and by sequential to those in which ...

Acid digestion and symbiont: Proton sharing at the origin of mitochondriogenesis?

BioEssays, Volume 45, Issue 1, January 2023., 2023
ADMit hypothesis for the origin of eukaryotes. A bacterial symbiont became associated with a protophagocytic host that captured prey with membrane processes. The symbiont cooperated to kill and digest the prey with reactive oxygen species and the acidification of the microenvironment.

Multi-fidelity Bayesian Optimisation of Syngas Fermentation Simulators [PDF]

arXiv, 2023
A Bayesian optimization approach for maximizing the gas conversion rate in an industrial-scale bioreactor for syngas fermentation is presented. We have access to a high-fidelity, computational fluid dynamic (CFD) reactor model and a low-fidelity ideal-mixing-based reactor model. The goal is to maximize the gas conversion rate, with respect to the input

Computational fluid dynamics simulation improves the design and characterization of a plug‐flow‐type scale‐down reactor for microbial cultivation processes

Biotechnology Journal, Volume 18, Issue 1, January 2023., 2023
Graphical Abstract and Lay Summary The heterogenous production conditions in large‐scale bioreactors cause scale‐up problems, such as reduced biomass or product yield, to occur during bioprocesses. In this study, we designed a two‐compartment scale‐down reactor and used it to simulate large‐scale heterogenous production conditions, allowing us to ...

Does inter-organellar proteostasis impact yeast quality and performance during beer fermentation? [PDF]

, 2019
During beer production, yeast generate ethanol that is exported to the extracellular environment where it accumulates. Depending on the initial carbohydrate concentration in the wort a high concentration of ethanol can be achieved in beer, often higher than 20% (v/v). It is noteworthy that the effects of elevated ethanol concentrations generated during
