Prevalence and growth potential of Listeria monocytogenes in innovative, pre-packed, plant-based ready-to-eat food products on the Belgian market
Int J Food Microbiol. 2023 Nov 25;410:110506. doi: 10.1016/j.ijfoodmicro.2023.110506. Online ahead of print.ABSTRACTIn recent years, pre-packed ready-to-eat (RTE) food products on the Belgian market have shifted to a more plant-based composition due to a variety of reasons, including consumer concerns about health, animal welfare, and sustainability. However, similar to animal-based RTE foods, plant-based RTE foods can be susceptible to the presence and outgrowth of Listeria monocytogenes (L. monocytogenes). Three innovative, pre-packed, plant-based RTE food product categories on the Belgian market were identified based up...

Metabolyc syndrome: A possible food tools to use in primary intervention
Rationale: Nowadays, in the human diet there is a widespread de ﬁcit of different mineral components that influence body healthy development therefore many studies on biofortiﬁcation (enriching) cultivated plants in various elements are started everywhere in the world. The agro technical method of biofortifying plants with mineral components are considered a s one of the cheapest ways leading to the reduction deﬁcits in the human and animal diet. The eﬀect of iodine and molybdenum salt on basic physiological and biochemical processes in lettuce grown are quite known therefore we evaluated on heathy population, the ...

Plant polyphenols biofortified food as a tool for ameliorating hepatic, lipid and bone homeostasis in older adults
Rationale: Lettuce is a source of fibers, which promote satiety, vitamin C, flavonoids and phenolic acids. By the application of positive stress (eustress) such as moderate saline stress, it is possible to increase the biosynthesis and accumulation of phenolic compounds of lettuce. Data on the effects on human health of the consumption of this type of polyphenols enriched (PE) lettuce are missing. The aim of the study is to verify if supplementation for twelve days with PE lettuce ameliorates homeostasis in a population of senior people. (Source: Clinical Nutrition ESPEN)

Effects of vermicompost on soil microbiological properties in lettuce rhizosphere: An environmentally friendly approach for sustainable green future
Environ Res. 2023 Nov 28:117737. doi: 10.1016/j.envres.2023.117737. Online ahead of print.ABSTRACTThe aim of this study is to investigate the effects of vermicompost on the biological and microbial properties of lettuce rhizosphere in an agricultural field in Samsun, Turkey. The experiment was conducted in a completely randomised design (CRD) and included four vermicompost dosages (0%, 1%, 2%, and 4%) and two application methods (with and without plants). Batavia lettuce was selected as the test plant due to its sensitivity to environmental conditions and nutrient deficiencies. The study evaluated the changes in organic ma...

Isolation and characterization of phage ISTP3 for bio-control application against drug-resistant Salmonella
Salmonella including drug-resistant strains are major foodborne pathogens causing serious illness and pose a great threat to the prevention and control for food safety. Phages can naturally defect the bacterium, is considered as a new and promising biological antimicrobial agent in the post-antibiotic era. A poultry facility in Wuhan, China provided wastewater samples from which a collection of 29 phages were isolated and purified. A broad host spectrum phage ISTP3, which capable of infecting all tested Salmonella, including drug-resistant Salmonella enterica, were examined. Additionally, the effectiveness of this phage IS...

Identification and complete genome sequence of a novel sadwavirus discovered in chrysanthemum (Chrysanthemum morifolium Ramat.)
AbstractThe complete genome sequence of a putative novel member of the genusSadwavirus was determined by high-throughput sequencing of a chrysanthemum from an orchard of the Tongxiang Agricultural Science Institute in Tongxiang, Zhejiang province. The complete genome sequence was confirmed using RT-PCR and the rapid amplification of cDNA ends (RACE) method. The predicted genome of the putative virus is composed of two RNA molecules, 7016 and 6772 nucleotides in length, excluding their poly-A tails. The new virus was tentatively named “chrysanthemum sadwavirus” (ChSV). The Pro-Pol region of RNA1 and the CP region of RNA...

Sensors, Vol. 23, Pages 9251: Quantitative and Qualitative Analysis of Agricultural Fields Based on Aerial Multispectral Images Using Neural Networks
This article presents an integrated system that uses the capabilities of unmanned aerial vehicles (UAVs) to perform a comprehensive crop analysis, combining qualitative and quantitative evaluations for efficient agricultural management. A convolutional neural network-based model, Detectron2, serves as the foundation for detecting and segmenting objects of interest in acquired aerial images. This model was trained on a dataset prepared using the COCO format, which features a variety of annotated objects. The system architecture comprises a frontend and a backend component. The frontend facilitates user interaction and annot...

Automated micro-solid-phase extraction clean-up and gas chromatography-tandem mass spectrometry analysis of pesticides in foods extracted with ethyl acetate
In this study, an automated procedure using µSPE cartridges was developed and established on an x,y,z robotic sampler for the raw extract clean-up and preparation of diluted samples for injection on a GC-MS/MS system. Validation experiments for 212 pesticides, polychlorinated biphenyls, and polycyclic aromatic hydrocarbons in lettuce, avocado, raspberry, paprika, egg, and liver extracts were performed using µSPE with MgSO4, PSA, C18, and CarbonX. The performance in routine operation is briefly discussed.PMID:37971663 | DOI:10.1007/s00216-023-05027-5 (Source: Analytical and Bioanalytical Chemistry)

Characterization and genomic insight of surfactin-producing Bacillus velezensis and its biocontrol potential against pathogenic contamination in lettuce hydroponics
Environ Sci Pollut Res Int. 2023 Nov 11. doi: 10.1007/s11356-023-30871-4. Online ahead of print.ABSTRACTDue to food borne pathogen, maintaining the viability of fresh fruits and vegetable is a great concern. Several strategies including microbial and plant-based formulations to reduce their infection and maintain quality of the fresh food are in practice. Currently, Bacillus has gained significant traction as a biocontrol agent for regulating diseases affecting a variety of agricultural and horticultural crops. Food-grade citric acid and plant growth-promoting rhizobacteria (PGPR) were used as antimicrobial agent, MIC resu...
