Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
the STEC strain from the endogenous E.coli strains while an Illumina MiSeq run takes 48 hours. Moreover, the lower-cost Flongle flow cell showed the same results after 24 hours of sequencing when using ...
Comparison of 6 DNA extraction methods for isolation of high yield of high molecular weight DNA suitable for shotgun metagenomics Nanopore sequencing to detect bacteriaAbstractBackgroundResultsConclusion
evaluated the performances of 6 DNA extraction methods using various cells lysis and purification techniques, from quick and easy, to more time-consuming and gentle protocols, including a portable method for ...
Development of a taxon-specific real-time PCR method targeting the Bacillus subtilis group to strengthen the control of genetically modified bacteria in fermentation products
fermentation products, such as enzymes, additives and flavorings, belong to the Bacillus subtilis group. Recently, unexpected contaminations with unauthorized genetically modified (GM) bacteria (viable cells ...
Development, Validation and Application of a Targeted LC-MS Method for Quantification of Microcystins and Nodularin: Towards a Better Characterization of Drinking Water
(PPIIA), disrupting cell growth and metabolism [15,16]. When ingested, these toxins are transported by the bile salts to the liver, potentially causing liver damage [17,18,19]. Health Topics: Food ...
Listeria monocytogenes isolates from Cornu aspersum snails: Whole genome-based characterization and host-pathogen interactions in a snail infection model.
infection model showed that hypervirulent isolates triggered programmed host cell death pathway by increasing up to 30% the circulating apoptotic hemocytes in combination with induced nitrate production and ...
