The biogenic amines (BAs), water activity, pH, thiobarbituric acid-reactive substances (TBARS), and nitrite were, respectively, tested in dry fermented sausage with starter cultures (37x-6 , x3-3b , 30x-11 , and 37x-8 . ), during storage of room temperature (20°C) and refrigeration storage (4°C). Tryptamine (TRM), 2-phenylethylamine (PHE), putrescine (PUT), cadaverine (CAD), histamine (HIM), and tyramine (TYM) contents of all samples were increased storage at 20°C, and the content of TRM, PUT, CAD, and HIM of all samples storage at 20°C was higher than that storage at 4°C after 42 days. The content of BA with 37x-6, x3-3b, and 37x-8 was obviously decreased at 4°C storage. The storage temperature has a significant effect on BA content ( < .05) for TYM and other BAs tested. Finally, x3-3b, 37x-6, and 37x-8 should be used to produce fermented sausages on the basis of the concentration of BAs.

Cheese-associated microbiota and their interactions are crucial in determining the properties of cheese. This study aimed to compare the effects of different starter cultures on Cheddar cheese production using texture analysis, electronic sensory evaluation, and both volatile and non-volatile metabolomics. Specifically, we examined Lactococcus lactis BL19 and Lactococcus cremoris LC99, both individually and in combination.

The discussion on tackling childhood obesity is often centered around fostering physical activity. A potential relationship yet overlooked could run from providing the proper environment for healthy lifestyles to reduced weight problems. A unique quasi-experimental setting of transforming former airport grounds to a large urban green space allows me to apply a difference-in-differences approach within an intention-to-treat framework, comparing several weight outcomes of residential children to children living further away before and after park opening.

Single cell genomics has revolutionized our understanding of neuronal cell types. However, scalable technologies for probing single-cell connectivity are lacking, and we are just beginning to understand how molecularly defined cell types are organized into functional circuits. Here, we describe a protocol to generate high-complexity barcoded rabies virus (RV) for scalable circuit mapping from tens of thousands of individual starter cells in parallel.

This study explores the potential of indigenous non- yeasts isolated from L. grape skins to improve the quality of regional wines by enhancing their physicochemical and sensory characteristics. Five promising yeast strains were identified at different stages of fermentation: (J1Y-T1), (Y5P-T5), (JF3-T1N), (Y8P-T8), and (WMP4-T4).
