Analysis of biomass productivity and physiology of Nitrososphaera viennensis grown in continuous culture

Frontiers in Microbiology, 2023
Microbial ammonia oxidation is the first and usually rate limiting step in nitrification and is therefore an important step in the global nitrogen cycle. Ammonia-oxidizing archaea (AOA) play an important role in nitrification.

Continuous fed-batch strategy decreases acetic acid production and increases volatile ester formation in wines under high-gravity fermentation

OENO One, 2023
High sugar fermentation elevates acetic acid levels in wines, which can be avoided by applying the continuous fed-batch strategy. In this study, yeast gene expressions and wine volatile compounds were evaluated by quantitative real-time PCR (RT-qPCR ...
