1,3,4-Oxadiazole-based heterocyclic analogs (3a-3m) were synthesized cyclization of Schiff bases with substituted aldehydes in the presence of bromine and acetic acid. The structural clarification of synthesized molecules was carried out with various spectroscopic techniques such as FT-IR,H and C-NMR, UV-visible spectroscopy, and mass spectrometry. antifungal activity was performed against , and and analogs 3g, 3i, and 3m showed potent MIC at 200 µg/ml and excellent ZOI measurements of 17-21 nm.

The mass balance relates to the flux of water and product in a wash tank and the number of microbial cells released in the water, inactivated by the water disinfectant or transferred from the water back to the product. Critical variables describing microbial dynamics in water are: (i) the chemical oxygen demand (COD), as an indicator of the concentration of organic matter; (ii) free chlorine (FC) and particularly its antimicrobial fraction, hypochlorous acid (HOCl); and (iii) the microbial population levels.

Background: Antimicrobial resistance (AMR) is a silent pandemic causing 1.27 million deaths in 2019, disproportionately affecting low- and middle-income countries, but resistance among commensal microbiota and the determinants of carriage have not been widely reported. This cross-sectional household study aimed to determine the prevalence of carbapenem-resistant (CRE) and third-generation cephalosporin-resistant Enterobacterale (C3GRE) in a rural community in Ha Nam northern Vietnam, as well as the socio-demographic, behavioural, and environmental determinants of carriage.

Background: Continuous fermentation offers advantages in improving production efficiency and reducing costs, making it highly competitive for industrial ethanol production. A key requirement for Saccharomyces cerevisiae strains used in this process is their tolerance to high ethanol concentrations, which enables them to adapt to continuous fermentation conditions. To explore how yeast cells respond to varying levels of ethanol stress during fermentation, a two-month continuous fermentation was conducted.
