Kombucha Fermentation With Dried Starter Cultures: A Strategy for Microbial Stabilization via Spray and Freeze Drying

Journal of Food Science, Volume 90, Issue 8, August 2025.
ABSTRACT Kombucha production relies on complex microbial consortia, which often vary across batches, posing challenges for fermentation reproducibility, product standardization, and industrial scalability. This study explored the effects of spray drying (SD) and freeze drying (FD) on the viability and metabolic activity of kombucha starter cultures ...

Single Cell Protein Production From Ethanol: Model‐Based Bioreactor Operation at Industrial Scale

Biotechnology and Bioengineering, Volume 122, Issue 6, Page 1441-1460, June 2025.
ABSTRACT Alternative fermentation feedstocks such as ethanol can be produced from CO2 via electrocatalytic processes that coproduce O2. In this study, industrial‐scale fermentation of ethanol with pure O2 for single cell protein (SCP) production was studied using a modeling approach.

Reaction Engineering for Asymmetric R‐/S‐PAC Synthesis With Ephedrine or Pseudoephedrine Dehydrogenase in Pickering Emulsion

Engineering in Life Sciences, Volume 25, Issue 2, February 2025.
ABSTRACT The synthesis of enantiopure α‐hydroxy ketones, particularly R‐ and S‐phenylacetylcarbinol (PAC), represents an important process in the pharmaceutical industry, serving as a pivotal step in the production of drugs. Recently, two novel enzymes, ephedrine dehydrogenase (EDH) and pseudoephedrine dehydrogenase (PseDH), have been described.
