Metagenomics-based tracing of genetically modified microorganism contaminations in commercial fermentation products
feasibility of a metagenomic shotgun sequencing approach to investigate microbial contamination in fermentation products, focusing on source tracing of GMM strains using innovative strain deconvolution and ...
Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
the host depletion DNA extraction method. We then investigated the issue of the detection and characterization of genetically modified microorganisms (GMM s) in microbial fermentation products as a case ...
Metagenomic Characterization of Multiple Genetically Modified Bacillus Contaminations in Commercial Microbial Fermentation Products
frequently employed for manufacturing microbial fermentation products such as food enzymes or vitamins. Although the fermentation product is required to be pure, GMM contaminations have repeatedly been ...
A shotgun metagenomics approach to detect and characterize unauthorized genetically modified microorganisms in microbial fermentation products
Publication Type: Scientific poster, presentation or proceeding Authors: Florence E Buytaers; Marie-Alice Fraiture; Bas Berbers; Els Vandermassen; Stefan Hoffman; N. Papazova; Kevin Vanneste; Kathleen Marchal; Nancy Roosens; Sigrid C.J. De Keersmaecker So ...
Characterization of Genetically Modified Microorganisms Using Short- and Long-Read Whole-Genome Sequencing Reveals Contaminations of Related Origin in Multiple Commercial Food Enzyme Products.
commercial microbial fermentation produce types. Several of these contaminations are related to a GM used to synthesize a food enzyme protease, for which genomic characterization remains currently incomplete, ...
Development of a real-time PCR marker targeting a new unauthorized genetically modified microorganism producing protease identified by DNA walking
real-time PCR GMM protease2 marker was also demonstrated on microbial fermentation products. To confirm its use by other GMO enforcement laboratories, the transferability of the in-house validated real-time ...
A shotgun metagenomics approach to detect and characterize unauthorized genetically modified microorganisms in microbial fermentation products
microbial fermentation products shotgun metagenomics Abstract: The presence of a genetically modified microorganism (GMM) or its DNA, often harboring antimicrobial resis- tance (AMR) genes, in microbial ...
Retrospective survey of unauthorized genetically modified bacteria harbouring antimicrobial resistance genes in feed additive vitamin B2 commercialized in Belgium: Challenges and solutions
used to produce vitamin B2, and a set of antimicrobial resistance (AMR) genes commonly harboured as selection marker by GM bacteria used to produce microbial fermentation products. On this basis, ...
Detection strategy targeting a chloramphenicol resistance gene from genetically modified bacteria in food and feed products
resistance gene Food and feed microbial fermentation products Genetically modified microorganisms PCR-Based detection Abstract: Genetically modified microorganisms (GMM), harbouring commonly antimicrobial ...
Concomitant microbial generation of palladium nanoparticles and hydrogen to immobilize chromate.
removal, while in control experiments with killed or viable but Pd-free bacterial cultures no reductive Cr(VI) removal was observed. Our results suggest a novel process where the in situ microbial production ...
