Sampling of agricultural and natural environments in two US states (Colorado Florida) yielded 18 Listeria-like isolates that could not be assigned to previously described species using traditional methods. Using whole-genome sequencing phenotypic methods, we identified five novel species, each with a genome-wide average BLAST nucleotide identity (ANIb) less than 85% currently species. Phylogenetic analysis based on 16S rRNA gene sequences amino acid 31 conserved loci showed the existence...
While the food-borne pathogen Listeria monocytogenes can persist in food associated environments, there are no whole-genome sequence (WGS) based methods to differentiate persistent from sporadic strains. Whole-genome sequencing of 188 isolates a longitudinal study L. retail delis was used (i) apply single-nucleotide polymorphism (SNP)-based phylogenetics for subtyping monocytogenes, (ii) use SNP counts repeatedly reintroduced strains, and (iii) identify genetic determinants persistence. WGS...
Managing deoxynivalenol (DON) risks is crucial for the sustainability of small grain farms. One approach involves profitable utilization contaminated resources, addressing potential losses from food safety concerns. This study explored distillation as a high-value alternative utilizing DON-contaminated grain. Naturally rye and wheat were used in two pilot-scale runs involving milling, mashing, fermentation, distillation. The ground grain, slurry, fermented mash, post-distillation mash...
ABSTRACT The persistence of Listeria monocytogenes in food-associated environments represents a key factor transmission this pathogen. To identify persistent and transient strains associated with production fermented meat sausages northern Portugal, 1,723 L. isolates from raw material finished products 11 processors were initially characterized by random amplification polymorphic DNA (RAPD), PCR-based molecular serotyping, epidemic clone characterization, as well cadmium, arsenic,...
ABSTRACT The organic acids lactate and diacetate are commonly used in combination ready-to-eat foods because they show synergistic ability to inhibit the growth of Listeria monocytogenes . Full-genome microarrays were investigate transcriptomic responses two L. strains, H7858 (serotype 4b) F6854 1/2a), these under conditions representing osmotic cold stress encountered foods. Strains exposed brain heart infusion (BHI) broth at 7°C with 4.65% water-phase (w.p.) NaCl pH 6.1 (i) 2% w.p....
Tomato is the main vegetable cultivated under soilless culture systems (SCSs); production of organic tomato SCSs has increased due to consumer demands for healthier and environmentally friendly vegetables. However, been associated with low crop performance fruit quality defects. These agricultural deficiencies could be linked alterations in plant microbiota; nonetheless, this issue not sufficiently addressed. Thus, goal present study was characterize rhizosphere phyllosphere plants...
Yarrowia lipolytica, an oleaginous yeast, shows promise for industrial fermentation due to its robust acetyl-CoA flux and well-developed genetic engineering tools. However, lack of active xylose metabolism restricts the conversion cellulosic sugars valuable products. To address this, metabolic engineering, adaptive laboratory evolution (ALE) were applied Y. lipolytica PO1f strain, resulting in efficient xylose-assimilating strain (XEV). Whole-genome sequencing (WGS) XEV followed by reverse...
Abstract Background The foodborne pathogen Listeria monocytogenes causes the potentially lethal disease listeriosis. Within food-associated environments, L. can persist for long periods and increase risk of contamination by continued presence in processing facilities or other environments. Most research on phenotyping persistent ’ has explored biofilm formation sanitizer resistance, with less data examining phenotypic responses to extrinsic factors, such as variations osmotic pressure, pH,...
