Phenolic Compounds, Antioxidant Activity, Sensorial Analysis and Metabolic Syndrome Enzyme Inhibition Properties of Calafate (Berberis microphylla) Fruit Juice Fermented by Patagonian Lactic Acid Bacteria.

Calafate is a native barberry of Patagonia, used in culinary and medicinal practices since ancient times. The aim of this work was to analyze the ability of lactic acid bacteria (LAB) isolated from calafate fruits and flowers, to increase the phenolic compound concentration and antioxidant capacity as well as to inhibit metabolic-related enzymes in fermented calafate juices. The sensory attributes of the selected fermented juice were also analyzed.

Selenium-enriched fermented beverage with improved sensorial properties using lactic acid bacteria.

Unlabelled: The aim of this study was to formulate a Selenium (Se)-bioenriched fermented beverage using selenized lactic acid bacteria (LAB) with desirable sensory attributes and shelf-life. The fruit-origin strains CRL 2051 and CRL 2034 were grown in MRS-fructose with 5 mg/L Se before inoculation. Then, the selenized strains were inoculated separately or together in a fruit juice and cowmilk beverage and allowed to ferment at 30 °C for 14 h.

Fermented pomegranate juice enriched with pomegranate seed oil ameliorates metabolic disorders associated with a high-fat diet in C57BL/6 mice.

This study investigated the health-functional properties of a lactic fermented pomegranate juice (FPJ) enriched with pomegranate seed oil (FPJO) by using the fruit-origin strain Lactiplantibacillus paraplantarum CRL 2051 (FPJO-CRL2051). For this aim, the in vitro human antiplatelet aggregation effect and antioxidant activities were determined in the fermented juices while in vivo studies using high-fat-diet (HFD) C57BL/6 mice fed with a high-fat diet or pomegranate fermented juices for 8 weeks were performed. A high anti-platelet aggregation activity for FPJO-CRL2051 was determined.

Selenium bioactive compounds produced by beneficial microbes.

Selenium (Se) is an essential trace element present as selenocysteine (SeCys) in selenoproteins, which have an important role in thyroid metabolism and the redox system in humans. Se deficiency affects between 500 and 1000 million people worldwide. Increasing Se intake can prevent from bacterial and viral infections.

Genomic diversity in Fructobacillus spp. isolated from fructose-rich niches.

The Fructobacillus genus is a group of obligately fructophilic lactic acid bacteria (FLAB) that requires the use of fructose or another electron acceptor for their growth. In this work, we performed a comparative genomic analysis within the genus Fructobacillus by using 24 available genomes to evaluate genomic and metabolic differences among these organisms. In the genome of these strains, which varies between 1.
