WGS analysis of two Staphylococcus aureus bacteriophages from sewage in China provides insights into the genetic feature of highly efficient lytic phages.

The study of bacteriophages is experiencing a resurgence with the increasing development of antimicrobial resistance in Staphylococcus aureus. Nonetheless, the genetic features of highly efficient lytic S. aureus phage remain to be explored.

Isolation and Characterization of a Lytic Vibriophage OY1 and Its Biocontrol Effects Against spp.

species are important pathogens of marine animals and aquaculture populations and some of them can cause serious infections in humans through consumption of contaminated seafood and aquaculture products. Lytic bacteriophages can potentially alleviate contamination in the aquaculture organisms and in the processing of aquatic products and have gained significant scientific attention in recent years. In the present study, bacteriophages were isolated from sewage of local aquatic products markets and grown using CICC 21613 as host cells.

Isolation and Characterization of a Virulent Bacteriophage for Controlling Salmonella Enteritidis Growth in Ready-to-Eat Mixed-Ingredient Salads.

Abstract: Ready-to-eat vegetable salads have gained popularity worldwide. However, the microbial safety of these salads is a health concern, primarily due to Salmonella Enteritidis contamination during the growing, harvesting, processing, and handling of produce. In this study, a bacteriophage-based strategy was developed to control Salmonella Enteritidis growth in mixed-ingredient salads.

Isolation and genomic characterization of P.A-5, a novel virulent bacteriophage against Enterobacter hormaechei.

Enterobacter hormaechei is a foodborne pathogen responsible for neonatal sepsis in humans and respiratory disease in animals. In this work, a new virulent phage (P.A-5) infecting E.

Physicochemical and antibacterial properties of fabricated ovalbumin-carvacrol gel nanoparticles.

The applications of carvacrol are limited due to its poor stability and water solubility, and high volatility; however, ovalbumin can be used to encapsulate hydrophobic molecules, improve their aqueous solubility, and reduce their volatility. In this study, we fabricated ovalbumin-carvacrol nanoparticles (OCGns) under different pH (2, 5, 7, and 9) conditions using a gel embedding method and investigated their physicochemical and antibacterial properties. Rheological experiments revealed that the G' of ovalbumin gels (OGs) prepared under different pH conditions were OG-2 > OG-7 > OG-9 > OG-5.

Isolation of virulent phages infecting dominant mesophilic aerobic bacteria in cucumber pickle fermentation.

Pickle is a type of mildly lactic acid fermented vegetable and is a traditional dish favored in China, Japan, and Korea. Corruption of spoilage bacteria and accumulation of nitrite during vegetable fermentation are common problems that affect the pickle industry and consumer health. In this work, cucumber juice was used as a vegetable model to study the dominant mesophilic aerobic bacteria (MAB) producing nitrite during pickle fermentation.

Down-regulation of BnDA1, whose gene locus is associated with the seeds weight, improves the seeds weight and organ size in Brassica napus.

Brassica napus L. is an important oil crop worldwide and is the main raw material for biofuel. Seed weight and seed size are the main contributors to seed yield.
