Biosynthesis of beta-phenylethanol is studied in a cell-free rose petals extract. This compound found to be synthesized via two intermediates: either trans-cinnamic acid, or phenylacetaldehyde. Subsequently beta-phenylethanol is glucosodized into its transport form, beta-phenylethanol- beta-D-glucoside. A scheme of beta-phenylethanol and its beta-D-glucoside is given.

Yeasts play a crucial role in determining the quality and yield of sauce-flavor Baijiu, yet the source, succession, and metabolic functions of the yeast community in fermented grains during stacking fermentation remains unclear. In this study, amplicon sequencing combined with solid-state fermentation was used to investigate the structure and function of yeast community during the first-round fermentation of sauce-flavor Baijiu. The richness and diversity of yeast community increased throughout fermentation, with 83.

Dabie Mountain Laboratory, College of Tea and Food Science, Xinyang Normal University, Xinyang, 464000, Henan, China.

Hydroxytyrosol, a fine chemical, is widely utilized in food and pharmaceutical industries. In this study, we constructed a pathway to produce hydroxytyrosol by co-expressing tyrosin-phenol lyase (TPL), L-amino acid dehydrogenase (aadL), α-keto acid decarboxylase (KAD), aldehyde reductase (yahK) and glucose dehydrogenase (gdh). We changed combinations between plasmids with different copy numbers and target genes, resulting in 84% increase in hydroxytyrosol production.

Purpose: Approximately 20% of all breast cancer cases are classified as triple-negative breast cancer (TNBC), which represents the most challenging subtype due to its poor prognosis and high metastatic rate. Caffeic acid phenethyl ester (CAPE), the main component extracted from propolis, has been reported to exhibit anticancer activity across various tumor cell types. This study aimed to investigate the effects and mechanisms of CAPE on TNBC.
