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
level, were specifically designed for this application and need to be assessed. Results: In this study, with different bacterial cocktail mixes, analyzed as pure or spiked in a synthetic fecal matrix, we ...
Targeted High-Throughput Sequencing Enables the Detection of Single Nucleotide Variations in CRISPR/Cas9 Gene-Edited Organisms
analytical and interpretation levels since this requires methodological approaches that can target and detect a specific single nucleotide variation (SNV) introduced into a GE organism. In this study, we ...
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
contaminations consisted of GM Bacillus species belonging to the B. subtilis group. In order to screen for the potential presence of such contaminations, in this study we have developed a new real-time PCR ...
Shotgun metagenomics as a ONE Health tool for better protecting human health
species in various concentrations and carrying AMR and/or virulence genes, taking the specific need of each application into account. Moreover, the short read and long read approaches are being compared to ...
A shotgun metagenomics approach to detect and characterize unauthorized genetically modified microorganisms in microbial fermentation products
fermentation products on the market is prohibited by European regulations. GMM s are currently screened for through qPCR assays targeting AMR genes and vectors, and then confirmed by targeting known specific GM ...
Retrospective survey of unauthorized genetically modified bacteria harbouring antimicrobial resistance genes in feed additive vitamin B2 commercialized in Belgium: Challenges and solutions
feed additive vitamin B2 products. To this end, two real-time PCR markers specific to this unauthorized genetically modified microorganism (GMM), named UGMV it- B2 and 558, were used. In the present ...
Development of a genoserotyping system for the identification of Salmonella serotypes
a complex classification system into 2 species, 6 subspecies and more than 2500 serotypes. The severity of salmonellosis is highly conditioned by, amongst other factors, the infected host species and the ...
Strategy for the identification of micro-organisms producing food and feed products: Bacteria producing food enzymes as study case
amplification and sequencing of the 16S-rRNA gene, the potential presence of FE producing bacteria in FE preparations. First, the specificity was verified using all microbial species reported to produce FE. ...
Tobacco, Sunflower and High Biomass SRC Clones Show Potential for Trace Metal Phytoextraction on a Moderately Contaminated Field Site in Belgium.
valorization. To find out which high biomass crop possessed the highest and most constant (in time) phytoextraction potential on these soils, different plant species and different mutants or clones of each ...
Pyrrolizidine alkaloids in herbs and related foodstuffs (PASHERBS)
herbs meals Pyrrolizidine alkaloids Abstract: Pyrrolizidine alkaloids (PA s) and their N-oxides (PANO s) are natural toxins, exclusively biosynthesized by a wide variety of plant species (>6000). They ...
