is a primary seafood-associated pathogen that could cause gastroenteritis. It can attach to various surfaces and form a biofilm, which poses serious threats to food safety. Hence, an effective strategy is urgently needed to control the biofilm formation of . Laurel essential oil (LEO) is used in food, pharmaceutical and other industries, and is commonly used as a flavoring agent and valuable spice in food industries. The potential antibiofilm effects of LEO against were examined in this study. LEO obviously reduced biofilm biomass at subinhibitory concentrations (SICs). It decreased the metabolic activity and viability of biofilm cells. Microscopic images and Raman spectrum indicted that LEO interfered with the structure and biochemical compositions of biofilms. Moreover, it also impaired swimming motility, decreased hydrophobicity, inhibited auto-aggregation and reduced attachment to different food-contact surfaces. RT-qPCR revealed that LEO significantly downregulated transcription levels of biofilm-associated genes of . These findings demonstrate that LEO could be potentially developed as an antibiofilm strategy to control biofilms in food industries.

Article Synopsis
- The study aimed to establish epidemiological cut-off values for the minimum inhibitory concentrations (MICs) of 10 antimicrobial agents against the bacteria Vibrio parahaemolyticus using standardized testing methods.
- Eight laboratories conducted broth microdilution tests at two different temperatures (35°C and 28°C) to assess the effect of incubation temperature on MIC values, finding that many values were consistent across both temperatures.
- The generated data will be submitted to the Clinical and Laboratory Standards Institute to help set international standards for interpreting antimicrobial susceptibility tests for this species.
Membrane Vesicles Can Contribute to Cellulose Degradation by Teredinibacter turnerae, a Cultivable Intracellular Endosymbiont of Shipworms.

Teredinibacter turnerae is a cultivable cellulolytic Gammaproteobacterium (Cellvibrionaceae) that commonly occurs as an intracellular endosymbiont in the gills of wood-eating bivalves of the family Teredinidae (shipworms). The genome of T. turnerae encodes a broad range of enzymes that deconstruct cellulose, hemicellulose and pectin and contribute to wood (lignocellulose) digestion in the shipworm gut.

Here, we investigate the Juno (JADE, JEDI, and MAG) observations of the magnetodisk within 20-80 Jupiter radii ( ) in the 0-6 hr local time sector. JADE and JEDI data are combined to generate equatorial plane distributions of density, pressure, temperature, and anisotropy of electrons, protons, and heavy ions.
