Characterization and Bioactive Potential of Carotenoid Lutein from GH-1 Isolated from Traditional Pixian Douban.

The characterization and bioactive properties of carotenoid produced by GH-1 originating from Pixian Douban (PXDB), the Chinese traditional condiment, was investigated. The produced and purified yellow pigment was characterized by ultraviolet-visible spectroscopy (UV-Vis), Fourier transformed infrared (FTIR), nuclear magnetic resonance (NMR), and high-resolution mass spectrometry (HRMS), and was identified as carotenoid lutein. Additionally, the bioactive activity of lutein from GH-1 was evaluated by measuring the free radical scavenging capacity in vitro and feeding zebrafish lutein through aqueous solution.

The Use of γ-Aminobutyric Acid-Producing SC125 for Functional Fermented Beverage Production from Apple Juice.

The development of functional fermented beverages enriched with γ-aminobutyric acid (GABA) has been pursued because of the health benefits of GABA; however, few studies have described GABA production by yeast. Therefore, this study aimed to produce fermented apple beverages enriched with GABA produced by SC125. Golden Delicious apples were fermented by SC125 to produce a novel functional beverage; commercial yeast was used as the control.

Characterization and Antioxidant Activity of Released Exopolysaccharide from Potential Probiotic LM187.

A released exopolysaccharide (rEPS)-producing strain (LM187) with good acid resistance, bile salt resistance, and cholesterol-lowering properties was isolated from Sichuan paocai and identified as subsp. mesenteroides. The purified rEPS, designated as rEPS414, had a uniform molecular weight of 7.
