  1. Isolation and characterization of a novel phage vB_BceS_LY1 and its application to control newly isolated Bacillus cereus in milk and rice

    • LWT
    • Bacillus cereus is important foodborne pathogen that causes food poisoning and other non-gastrointestinal infections, which could cause nausea, vomiting and diarrhea. Phages have antibacterial potential to control this pathogen, especially antibiotic resistant ones. In this study, a novel lytic Bacillus cereus phage, vB_BceS_LY1 (LY1), a new genus of the subfamily Gutmannvirinae under Caudoviricetes, was isolated from a sewage treatment plant in China.

  3. A wound inducible chalcone synthase gene from Dysoxylum gotadhora (DbCHS) regulates flavonoid biosynthesis

    • Physiology and Molecular Biology of Plants
    • Chalcone synthase (CHS) is a type III polyketide synthase and a key enzyme of the phenylpropanoid pathway that generates precursors for flavonoid biosynthesis. The tree species D. gotadhora is known for having an abundance of rohitukine, which has anti-inflammatory and immune-modulating effects. In this study, we used the leaves of D. gotadhora to clone CHS gene (DbCHS). The 1188-bp open reading frame (ORF) was part of the 1373-bp full-length DbCHS clone.

  5. Engineered lytic phage of Bacillus cereus and its application in milk

    • International Journal of Food Microbiology
    • Phages have been approved for use in the food industry to control bacterial contamination in some countries. However, their broader adoption is hindered by some limitations. For instance, the persistence of infectious phages in the food industry can lead to the emergence of resistant bacteria, which negatively impacts the long-term effectiveness of phages. Additionally, the narrow host range of phages limits their effectiveness against various strains.
