Purine nucleosidase (PNase) activity, probiotics potential, and food applicability of a newly-isolated LAB42.

Hyperuricemia, a condition characterized by elevated levels of uric acid in the blood, is known as a risk factor for gout disease. In this study, we isolated a total of 72 MRS-grown colonies and evaluated their purine nucleosidase (PNase) activity. Among the isolated bacteria, LAB42 displayed the highest PNase activity.

Prevalence, Diversity and UV-Light Inducibility Potential of Prophages in and Their Possible Roles in Host Properties.

is an important bacterial species due to its various industrial, medicinal, and agricultural applications. Prophages are known to play vital roles in host properties. Nevertheless, studies on the prophages and temperate phages of are relatively limited.

Prevalence and Genetic Characterization of -Positive Isolated from Retail Meats in South Korea.

The spread of plasmid-mediated colistin resistance has posed a serious threat to public health owing to its effects on the emergence of pandrug-resistant bacteria. In this study, we investigated the prevalence and characteristics of -positive isolated from retail meat samples in Korea. In total, 1,205 strains were isolated from 3,234 retail meat samples in Korea.

High prevalence of Bacillus subtilis-infecting bacteriophages in soybean-based fermented foods and its detrimental effects on the process and quality of Cheonggukjang.

While the detrimental effect of bacteriophages on lactic acid bacterial fermentation is well documented, the importance of Bacillus subtilis phages in soybean-based fermented foods is not. In this study, we show for the first time that 100% of Korean soybean-based fermented foods (Doenjang, Gochujang, and Cheonggukjang) and 70% of raw materials (Meju and rice straw) were contaminated with B. subtilis-infecting phages (as high as 3.

Complete Nucleotide Sequence Analysis of a Novel -Infecting Bacteriophage BSP10 and Its Effect on Poly-Gamma-Glutamic Acid Degradation.

While the harmful effects of lactic acid bacterial bacteriophages in the dairy industry are well-established, the importance of -infecting bacteriophages on soybean fermentation is poorly-studied. In this study, we isolated a -infecting bacteriophage BSP10 from (a brick of dried fermented soybean) and further characterized it. This family bacteriophage exhibited a narrow host range against strains (17/52, 32.
