Clinical Origin and Species Distribution of spp. Isolates Identified by Molecular Sequencing and Mass Spectrometry: A European Multicenter Hospital Prospective Study.
to allow a fast, accurate and free-access identification of fungi by matrix-assisted laser desorption ionization-time of flight (MALDI- TOF) mass spectrometry. Taking advantage of the MSI database user ...
Targeted LC-MS/MS combined with multilocus DNA metabarcoding as a combinatory approach to determine the amount and the source of pyrrolizidine alkaloids contamination in popular cooking herbs, seeds, spices and leafy vegetables
multilocus DNA metabarcoding was performed on six highly contaminated samples, belonging to each subtype matrix, containing high levels of heliotrine type of PA / PANO s. Each time the analysis demonstrated ...
Adjunct Culture of Non-Starter Lactic Acid Bacteria for the Production of Provola Dei Nebrodi PDO Cheese: In Vitro Screening and Pilot-Scale Cheese-Making.
were genetically identified by Rep- PCR genomic fingerprinting, using the (GTG)-primer, and by matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI- TOF MS). Twenty-seven ...
CBD oils on the Belgian market: A validated MRM GC-MS/MS method for routine quality control using QuEChERS sample clean up
however, encountered for routine analyses due to the matrix complexity, high cost of cannabinoid standards and low Δ9- THC concentrations. An oily matrix could cause technical damages to analytical ...
Adjunct Culture of Non-Starter Lactic Acid Bacteria for the Production of Provola Dei Nebrodi PDO Cheese: In Vitro Screening and Pilot-Scale Cheese-Making
(GTG)5-primer, and by matrix-assisted laser desorption/ionisation time-of-flight mass spectrometry (MALDI- TOF MS). Twenty-seven strains, included in the qualified presumption of safety (QPS) list, were tested for ...
Influence of reduced levels or suppression of sodium nitrite on the outgrowth and toxinogenesis of psychrotrophic Clostridium botulinum Group II type B in cooked ham.
botulinum behavior in processing meat products, outgrowth and toxin production of C. botulinum should be evaluated on a case by case basis, depending on the recipe, manufacturing process, food matrix and ...
Unexpected mould diversity in clinical isolates from French Guiana and associated identification difficulties.
matrix-assisted laser desorption ionization time-of-flight mass spectrometry. In total, 38.8% of the 98 obtained molds isolates could not be identified and required a DNA-based identification. Fungal diversity was ...
Strain-Level Metagenomic Data Analysis of Enriched In Vitro and In Silico Spiked Food Samples: Paving the Way towards a Culture-Free Foodborne Outbreak Investigation Using STEC as a Case Study.
species, present in a microbial community, which has up until now not been demonstrated for this application. The current work shows the feasibility of strain-level metagenomics of enriched food matrix ...
A Practical Method to Implement Strain-Level Metagenomics-Based Foodborne Outbreak Investigation and Source Tracking in Routine.
outbreak depends on the rapid and accurate identification of the responsible food source. Conventional methods based on isolation of the pathogen from the food matrix and target-specific real-time polymerase ...
PT-2020-NRL-TE-FASFC “Determination of As, Cd, Pb and Hg in food supplements"
be derived for Hg. The measurement of As was difficult, but overall the laboratories performed satisfactory. The performance of the laboratories to analyse Pb, and Cd in this matrix was ...
