Glucose utilization by Brettanomyces bruxellensis at different acetic acid concentrations under aerobic and anaerobic conditions was investigated. The presence of the organic acid disturbs the growth and fermentative activity of the yeast when its concentration exceeds 2 g l(-1). A mathematical model is proposed for the kinetic behavior analysis of yeast growing in batch culture. A Matlab algorithm was used for estimation of model parameters, whose confidence intervals were also calculated at a 0.95 probability level using a t-Student distribution for f degrees of freedom. The model successfully simulated the batch kinetics observed at different concentrations of acetic acid under both oxygen conditions.

Background And Objectives: The most effective antiseizure medications (ASMs) for poststroke seizures (PSSs) remain unclear. We aimed to determine outcomes associated with ASMs in people with PSS.
Methods: We systematically searched electronic databases for studies on patients with PSS on ASMs.

Microbial transmission from mother to infant is important for offspring microbiome formation and health. However, it is unclear whether maternal gut inflammation (MGI) during lactation influences mother-to-infant microbial transmission and offspring microbiota and disease susceptibility. In this study, it is found that MGI during lactation altered the gut microbiota of suckling pups by shaping the maternal microbiota in the gut and mammary glands.

Context: A chemical reaction can be described, from a physicochemical perspective, as a redistribution of electron density. Additionally, non-covalent interactions locally modify the electron density distribution. This study aims to characterize the modification of reactivity caused by the presence of non-covalent interactions such as hydrogen bonds, in a reaction involving the formation of two bonds and the breaking of two others: CH₃COOH + NH₂CH₃ → CH₃CONHCH₃.

The traditional treatment of toxic and refractory copper(II)-ethylenediaminetetraacetic acid chelate (Cu(II)-EDTA) in electroless effluents often generates hazardous waste and secondary nitrogen-containing pollutants without maximizing the resource recovery. This study demonstrates a facile strategy to simultaneously recover Cu and EDTA ligands from Cu(II)-EDTA electroless effluent with commercially available metallic Cu and formaldehyde. In this strategy, metallic Cu is used to activate formaldehyde, a prevalent yet often overlooked cocontaminant in Cu(II)-EDTA effluents, to produce highly reductive hydrogen radical (H), which in situ decomplex Cu(II)-EDTA, reduces the central Cu(II) into metallic Cu, and release EDTA ligand.
