In this study, we assessed the phytochemicals of beetroot (Beta vulgaris) extract (BE), and examined antibacterial activity possible mechanism BE against Bacillus cereus. The in were analyzed by UPLC-ESI-MS-based widely targeted metabolomics analysis, identified a total 745 phytochemicals. Nine polyphenols 19 flavonoids with growth-inhibiting B. cereus identified. minimum inhibitory concentration (MIC) was 15 mg/mL. intracellular adenosine 5′-triphosphate (ATP) levels decreased exhibited...

To investigate how casein hydrolysate affected the physicochemical properties and microbiological diversity of glutinous rice dough (natural fermentation yeast fermentation), we analyzed its properties, carbohydrate, protein degradation, texture, bacterial composition. According to findings, increased total LAB number, as well organic acid content, in naturally fermented by 3.59 8.19%, respectively, reduced time at least 2 h. Meanwhile, enhanced content reducing sugars 4.46 13.53% protease...

The proliferation of antibiotic usage has precipitated the emergence drug-resistant variants bacteria, thereby augmenting their capacity to withstand pharmaceutical interventions. Among these variants, Cronobacter sakazakii (C. sakazakii), prevalent in powdered infant formula (PIF), poses a grave threat well-being infants. Presently, global contamination by C. is being observed. Consequently, research endeavors have been initiated explore strain’s drug resistance capabilities, alterations...

The effect of a casein hydrolysate (CH) on the fermentation and quality naturally-fermented buckwheat dough (NFBD) were investigated, through assessing properties, carbohydrate, protein degradation, texture bacterial composition NFBD. assaying results showed that CH could shorten time by at least 3 h, increase amount lactic acid bacteria (LAB), which subsequently led to promoted degradation carbohydrates proteins accompanying with altered or microstructure. More importantly, in NFBD clear...
