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 ...
Safety assessment of titanium dioxide (E171) as a food additive
effects. With respect to genotoxicity, the Panel concluded that TiO2 particles have the potential to induce DNA strand breaks and chromosomal damage, but not gene mutations. No clear correlation was observed ...
Identifying nanodescriptors to predict the toxicity of nanomaterials: a case study on titanium dioxide
modelling. Agglomerate size as a nanodescriptor was well associated with biological endpoints such as DNA damage and/or cytotoxicity. We conclude that, agglomerate size is an important nanodescriptor to assess ...
Retrospective survey of unauthorized genetically modified bacteria harbouring antimicrobial resistance genes in feed additive vitamin B2 commercialized in Belgium: Challenges and solutions
highlighted. In addition, the possible complementary use of additional data, like chloramphenicol presence and DNA concentration, as indicators for GMM contaminations was assessed. Based on results generated in ...
Phytochemical screening, antioxidant, anticoagulant and in vitro toxic and genotoxic properties of aerial parts extracts of Fumaria officinalis L. growing in Tunisia
the bacterial Vitotox test. This was confirmed in the comet assay which was conducted on human C3A cells, except for the methanolic extract where DNA damage appeared to be significantly increased at ...
Strategy for the identification of micro-organisms producing food and feed products: Bacteria producing food enzymes as study case
regulations require safety assessments of food enzymes (FE) before their commercialization. FE are mainly produced by micro-organisms, whose viable strains nor associated DNA can be present in the final ...
Detection strategy targeting a chloramphenicol resistance gene from genetically modified bacteria in food and feed products
associated recombinant DNA. Although the use of AMR genes gives rise to public health and environmental concerns regarding their potential acquisitions by pathogens and gut microbiota, no method targeting AMR ...
Migration of mineral oil from cardboard packaging for food: Identification of the hazards and assessment of the exposure of the Belgian population
results were obtained, including further evidence that highly alkylated polycyclic aromatic hydrocarbons (PAH s) (which are important constituents of the MOAH fraction) are not metabolized into DNA ...
