Microbial Biotechnology, Volume 17, Issue 11, November 2024.Understanding microbial response to industrial‐scale conditions is imperative to achieve overall process robustness at industrial‐scale. Here, we studied E. coli's response to changing glucose and oxygen levels. We report lower biomass, higher acetate production, and key regulatory mechanisms that were altered under repeated oxygen limitation ...

Time dynamics of the Bacillus cereus exoproteome are shaped by cellular oxidation
Frontiers in Microbiology, 2015 At low density, Bacillus cereus cells release a large variety of proteins into the extracellular medium when cultivated in pH-regulated, glucose-containing minimal medium, either in the presence or absence of oxygen. The majority of these exoproteins are

Journal of Eukaryotic Microbiology, Volume 71, Issue 6, November/December 2024.Abstract Metamonads are a large and exclusively anaerobic group of protists. Additionally, they are one of the three clades proposed to ancestrally possess an “excavate” cell morphology, with a conspicuous ventral groove accompanied by a posterior flagellum with a vane.

MicrobiologyOpen, Volume 13, Issue 5, October 2024.The presence of microbiota did not affect the growth of Clostridioides difficile in this study. However, it did influence the expression of C. difficile genes related to sporulation, germination, and virulence, which are crucial for the transmission of the pathogen. In the presence of microbiota, C.

Methionine formation by transmethylation in vitro [PDF]
, 1947 We reported in a previous communication (1) that guanidoacetic acid is methylated to creatine by rat liver slices in the presence of choline and either homocysteine or homocystine.

Agronomy Journal, Volume 116, Issue 5, Page 2242-2262, September/October 2024.Abstract Ammonia (NH3) loss following manure application is an environmental concern and N loss for crop production. Manure injection typically reduces NH3 loss compared to surface application without incorporation but increases emissions of nitrous oxide (N2O), which is a potent greenhouse gas.
