Environmental factors such as stocking density can cause stress and negatively affect the physiological status and meat quality of broiler chickens. In the current study, we evaluated the effects of increased rearing density on the growth performance, stress, fear levels, meat quality and liver histopathology of broilers as well as suggesting a use of different supplementations that may be helpful to reverse such adverse effects. Three hundred sixty one day-old cobb broilers (44.0±5.24 g live-weights) were randomly distributed to 24 replicate pens to create two different stocking densities (D10 and D15 bird/m 2) with the different supplementation treatments: 1) 10 birds/m 2/pen (without any treatment, control," CD10"), 2) 10 birds/m 2/pen (moringa aqueous extract treatment" MAED10"), 3) 10 birds/m 2/pen (synbiotic" SynD10"), 4) 15 birds/m 2/pen (without any treatment control SD15" CD15"), 5) 15 birds/m 2/pen (moringa aqueous extract treatment" MAED15"), 6) 15 birds/m 2/pen (synbiotic" SynD15"). Results of the current study revealed that there was a significant increase in the overall experimental period body weight gain (P< 0.01) with increasing density without affecting feed intake, body weight and feed conversion ratio. High stocking density resulted in significantly increased corticosterone (P> 0.001), altered brain monoamines, deteriorated some carcass quality parameters and declined liver health. Additionally, it was concluded that moringa aqueous extract (MAE) and synbiotic (Syn) supplementation have a significant effect in reversing the catastrophic effect of high stocking density (SD) with minimal effect at the lower density groups.

Enhancing the productivity and bioactivity of high-functional foods holds great significance. Carbon nanoparticles (CNPs) have a recognized capacity for boosting both plant growth and the efficacy of primary and secondary metabolites. Furthermore, while salinity diminishes plant growth, it concurrently amplifies the production of phytomolecules. To ensure the robust and sustainable production of nutritious food, it becomes essential to elevate biomolecule yield without compromising plant growth. Here, we assessed the CNPs priming on plant performance and metabolites of the glycophyte amaranth (Amaranthus hypochondriacus) sprouts at the threshold salinity (25 mM NaCl; i.e., salinity that does not reduce growth but enhances the metabolites of that plant). We measured growth parameters, pigment levels, and primary (carbohydrates, amino acids, organic acids, fatty acids) and secondary metabolites (phenolics, flavonoids, tocopherols). CNP priming significantly improved biomass accumulation (fresh and dry weight) and primary and secondary metabolites of amaranth sprouts. Increased photosynthetic pigments can explain these increases in photosynthesis. Enhanced photosynthesis induced carbohydrate production, providing a C source for producing bioactive primary and secondary metabolites. The priming effect of CNPs further enhanced the accumulation of essential amino acids, organic acids, unsaturated fatty acids, tocopherols, and phenolics at threshold salinity. The increase in bioactive metabolites under threshold salinity can explain the CNP priming impact on boosting the antioxidant activities (FRAP, DPPH, anti-lipid …

This study was conducted to determine the antimicrobial activity of starch-based biodegradable antimicrobial films incorporated with biosynthesized silver nanoparticles (Ag-NPs) against multiple drug-resistant Staphylococcus aureus food isolates. Herein, the in-vitro antimicrobial activities of Origanum marjorana (OM) leaf extract, OM essential oil, OM nano-emulsion, chemically synthesized Ag-NPs (chem-Ag-NPs), and OM-based biosynthesized Ag-NPs (bio-Ag-NPs) using OM extracts were determined against a cocktail of three pathogenic Staphylococcus (S.) aureus strains isolated from meat products, using the agar well diffusion assay (AWDA). Afterward, homemade starch-based biodegradable antimicrobial films (SBAF) were incorporated with the suitable antimicrobials, based on AWDA and preliminary experiments, and investigated for their antimicrobial properties against S. aureus cocktail through the disc diffusion assay (DDA). The obtained results showed that in WDA, bio-Ag-NPs (1mM) had a significantly higher antimicrobial activity than chem-Ag-NPs (1mM), with inhibition zones accounting for 23 and 19mm, respectively. Whereas both types of nanoparticles were significantly more potent in their antimicrobial properties than different concentrations of OM extract, essential oil, and nano-emulsion (p< 0.05). In concern to SBAF incorporated with antimicrobials, SBAF incorporated with chem-Ag-NPs (SBAF/chem-Ag-NPs) showed a significantly stronger antimicrobial effect than SBAF incorporated with bio-Ag-NPs (SBAF/bio-Ag-NPs) in the DDA, while both types of films produced significantly larger zones of inhibition than other …

Thallium (TI) is a toxic metal that can trigger harmful impacts on growth and metabolism of plants. Utilizing arbuscular mycorrhizal fungi (AMF) proves to be an effective strategy for alleviating heavy metal toxicity in plants. To this end, AMF were applied to mitigate TI toxic effects on the growth, primary and secondary metabolism of soybean plants. Here, TI stress inhibited the growth and photosynthetic parameters of soybean plants. It also increased the oxidative damage as demonstrated by increased levels of oxidative markers, (MDA and lipoxygenase (LOX) activity). However, AMF could mitigate the reduction in growth and photosynthesis induced by TI, as well as the induction of oxidative damage. To overcome TI toxicity, AMF increased the levels and metabolism of osmolytes such as proline in soybean plants. This was in line with the increased activities of key enzymes that involved in proline biosynthesis (e.g …

Antimony (Sb), a common rare heavy metal, is found naturally in soils at low concentrations. This study aimed to understand the effect of low Sb concentrations on plant growth and metabolism. To this end, canola (Brassica napus L. var. napus) and turnip roots (Brassica rapa L. var. rapa) were treated with Sb at low concentrations (8 mg/kg soil) to explore the effect Sb on their growth, photosynthesis, glucosinolate metabolism, redox status, and biological activity. Our results revealed that Sb significantly promoted growth by 1.34 and 1.14-fold in B. napus and B. rapa compared to control conditions. This increase can be explained by the observed increase in photosynthesis as indicated by increased chlorophyll content. Low Sb concentration significantly improved total glucosinolate accumulation, through improved amino acid production, namely alanine, leucine, isoleucine, valine, methionine, phenylalanine, tyrosine, and tryptophan. There were increases in myrosinase activity, which stimulated glucosinolate hydrolysis to yield health-promoting sulforaphane. In contrast, a low level of ineffective sulforaphane nitrile was detected. Sb also improved antioxidant metabolites (tocopherol) and enzymes (CAT, POX, SOD) in both species but to a bigger extent in B. napus by 1.98, 2.77, 2.46, and 2.05 fold, respectively. In conclusion, although high Sb concentrations are toxic, low Sb concentrations can promote biomass and bioactive compound accumulation in Brassica spp.

Simple Summary Recently, novel food processing technologies have been used for the quality improvement of fruits and vegetables. Laser light application and 6-benzylaminopurine (BAP) priming are known to be promising approaches to improve the nutritional values of plants. In this study, we carried out novel food processing technologies using laser light and 6-benzylaminopurine (BAP) priming for the quality improvement of linseed sprouts. The combined treatments improved the accumulation of minerals, vitamins, and amino acids and enhanced the N-metabolism. Moreover, the application of both treatments combined enhanced the antioxidant capacity by increasing fatty acids, phenols, and flavonoids, as well as antimicrobial activity. Abstract Even though laser light (LL) and 6-benzylaminopurine (BAP) priming are well-known as promising strategies for increasing the growth and nutritional value of several plants, no previous studies have investigated their synergistic effect. Herein, we investigated the effects of laser light, 6-benzylaminopurine (BAP) priming, and combined LL-BAP treatment on the nutritional value, chemical composition, and the biological activity of Linum usitatissimum sprouts. The fresh weight, leaf pigments, primary and secondary metabolites, enzymes, and antimicrobial activities were determined. A substantial enhancement was observed in the growth characteristics and leaf pigments of laser-irradiated and BAP-primed sprouts. Furthermore, the combined treatments improved the accumulation of minerals, vitamins, and amino acids, and also enhanced the N-metabolism more than LL …

The demand for healthy foods with high functional value has progressively increased. Carbon nanoparticles (CNPs) have a promising application in agriculture including the enhancement of plant growth. However, there are few studies on the interactive effects of CNPs and mild salinity on radish seed sprouting. To this end, the effect of radish seed priming with 80mM CNPs on biomass, anthocyanin, proline and polyamine metabolism, and antioxidant defense system under mild salinity growth condition (25 mM NaCl). The results indicated that seed nanopriming with CNPs along with mild salinity stress enhanced radish seed sprouting and its antioxidant capacity. Priming boosted the antioxidant capacity by increasing antioxidant metabolites such as (polyphenols, flavonoids, polyamines, anthocyanin, and proline). To understand the bases of these increases, precursors and key biosynthetic enzymes of anthocyanin [phenylalanine, cinnamic acid, coumaric acid, naringenin, phenylalanine ammonia lyase, chalcone synthase (CHS), cinnamate-4-hydroxylase (C4H) and 4-coumarate: CoA ligase (4CL)], proline [pyrroline-5-carboxylate synthase (P5CS), proline dehydrogenase (PRODH), Sucrose, Sucrose P synthase, invertase) and polyamines [putrescine, spermine, spermidine, total polyamines, arginine decarboxylase, orinthnine decarboxylase, S-adenosyl-L-methionine decarboxylase, spermidine synthase, spermine synthase] were analyzed. In conclusion, seed priming with CNPs has the potential to further stimulate mild salinity-induced bioactive compound accumulation in radish sprouts.

Graphene-based nanomaterials received a lot of attention in agriculture. In this study, graphene oxide (GO) was modified with different amino acids (methionine and lysine) using a microwave approach, and yielded methionine on GO (Meth/GO), and lysine on GO (Lys/GO); The materials obtained had a significant impact on the colour, chemical components and molecular features of pearl millet grains grown under salt stress. Due to the effect of modified GO on the nutritious content of millet grains, its usage resulted in the homogeneity of the colour of the pearl millet grains to a great extent. Tannins and phytic acid contained in pearl millet grains, when ingested by humans or animals, can result as anti-nutritional factors, as they can form complexes with metal ions and vitamins, limiting the absorption of many molecules essential for nutrition. As a result, it is vital to reduce these substances. GO, Meth/GO, and Lys/GO …

Irresponsible use of antibiotics, inability to follow label guidelines, or insufficient withdrawal periods before slaughtering poultry could result in antibiotic residues in edible poultry tissues, thereby representing hazards to public health. Therefore, this study was conducted to determine the residual levels of three commonly used antimicrobials including oxytetracycline (OXY), enrofloxacin (ENRO), and sulfadimidine (SULFA) in muscle, skin, and giblets of chicken carcasses quantitatively. Additionally, the obtained residual values were compared to the maximum residue limits (MRLs) stated by the regulatory authorities. The findings denoted that the muscles of fresh domestic broilers had significantly higher values of OXY, ENRO, and SULFA than those of fresh native breeds and imported frozen chicken (p< 0.05). Similarly, in pooled giblets (equal weights of liver and kidneys), OXY and ENRO were significantly higher in domestic broilers than in native breeds (p< 0.05). Likewise, ENRO and SULFA residues were higher in skin samples of domestic broilers than in native breeds. In comparison to the MRLs reported by the European Commission, the muscles from 20, 60, and 50% of examined domestic broiler carcasses exceeded the MRLs of OXY, ENRO, and SULFA., respectively, whereas muscles from 20, 70, and 50% of examined native breed carcasses surpassed these MRLs, respectively. Conversely, in imported frozen broilers, no muscle samples topped the MRL of OXY, while 10% of the examined carcasses exceeded the MRLs of both ENRO and SULFA. Therefore, very extensive work is needed to monitor the antimicrobial residues in poultry …

Additionally, 60 swab samples from knives, cutting boards, and operator's hands were investigated for the same bacteriological criteria. Subsequently, bacterial isolates were subjected to molecular identification by investigating the presence of virulence and antibiotic resistance genes. The results showed that 100% of meat product samples at various stages of preparation contained aerobic bacterial load and Staph. aureus. Conversely, E. coli and L. monocytogenes were undetectable in meat product samples. Interestingly, 13, 7, and 1 out of 20 swab samples from hands contained coliforms, fecal coliforms, and E. coli, respectively, while knives and cutting boards were free from fecal coliforms and E. coli. Furthermore, contamination with Staph. aureus was reported in 100% of knives and hand swab samples and 50% of cutting board swab samples. Furthermore, the only E. coli isolate from a worker's hand contained eaeA gene, but not Stx1 gene, which indicates that it is an enteropathogenic E. coli (EPEC) strain.

Marrubium vulgare is a valuable source of natural bioactive molecules with high preventive and therapeutic effectiveness. Therefore, this study aimed to study the chemical polymorphism of natural populations of M. vulgare in Tunisia by quantitative chemical markers and the estimation of divergence between populations. Phytochemical analyses of the eight natural populations of Tunisian Marrubium vulgare prospected in different bioclimatic stages, revealed 42 compounds of essential oils representing 96.08% to 100% of the total oil. Hydrocarbon sesquiterpenes were the main fraction of all the populations studied and β-bisabolene was the major compound (from 30.11% to 71.35% of the total oil). The phytochemical investigation of the M. vulgare plant indicated the presence of essential oil with significant percentages of phenolic compounds. A significant quantitative and qualitative variation in the essential oils is detected for both major and minor compounds. The principal components analysis (PCA) performed in the single and combined traits provides a good distinction among populations, not according to their geographical and/or bioclimatic origins. Moreover, the phytochemical analysis of the leaves showed that the Tunisian populations, i.e., the populations of Kasserine, Kef, and Beja, were very rich in phenolic compounds (from 20.8 to 44.65 mg GAE/g DW). Flavonoids compounds were also the main class of total polyphenols present in all the tested populations (from 8.91 to 37.48 mg RE/g DW). The quantitative genetic diversity estimated by the population’s structure, based on PCA analysis, was an adaptation to the changes in the …

Therefore, the current study was conducted to investigate the antimicrobial effect of homemade biodegradable antimicrobial films incorporated with silver nanoparticles (Ag-NPs) against Staphylococcus aureus (S. aureus) experimentally inoculated in chicken breast. Chicken breast slices (5 × 5 cm) were experimentally inoculated with a cocktail of three S. aureus strains at a concentration of about 6.6 log10 CFU/cm2 and wrapped in homemade biodegradable antimicrobial films. Following that, the residual bacterial counts in wrapped chicken breast fillet slices were monitored for up to 10 days in a refrigerator (4 °C). It was found that at the end of the chilling period the films with biosynthesized Ag-NPs (1mM), biosynthesized Ag-NPs (2mM), chemically synthesized Ag-NPs (1mM), and chemically synthesized Ag-NPs (2mM) reduce the S. aureus counts by about 4.66, 5.24, 4.79, and 5.43 log10 CFU/cm2, respectively when compared with control films. Biodegradable antimicrobial films also prolonged the shelf-life of samples by approximately 4 days when compared to control samples.

Elevated atmospheric CO2 (eCO2) can significantly enhance plant metabolism and improve their nutritional quality. Although several studies addressed the effect of eCO2 on plants, to our knowledge, there are no studies that have applied eCO2 to improve growth, chemical composition, and biological properties of ajwain (Trachyspermum ammi) during sprouting. Herein, eCO2 (620 µmol mol−1) was employed to enhance photosynthetic reactions. Improved photosynthesis induced primary and bioactive secondary metabolism, which led to improved biological activities of T. ammi sprouts in comparison with control sprouts and seeds. eCO2-treated sprouts showed significantly (p < 0.05) higher levels of most measured nutritional primary and secondary metabolites like soluble sugars, essential amino acids, organic acids, essential oils, phenolics, and flavonoids than control sprouts, which had significantly higher values than control seeds. eCO2 significantly improved the antimicrobial properties of T. ammi sprouts against 11 out of 13 microbial species than control sprouts, which had more potent antimicrobial activities than seeds. The significant increase in the antioxidant potential of treated sprouts was indicated by improved levels of ferric reducing antioxidant power (FRAP), DPPH, and oxygen radical absorbance capacity (ORAC). In addition, the anticancer activity against four different human tumor cell lines was significantly (p < 0.05) boosted by both sprouting and eCO2 exposure. Thus, the present study confirms the synergistic effect of sprouting with eCO2 exposure as promising approaches to produce ajwain sprouts with rich nutraceuticals …

Compared to seeds and mature tissues, sprouts are well known for their higher nutritive and biological values. Fruits of Pimpinella anisum (anise) are extensively consumed as food additives; however, the sprouting-induced changes in their nutritious metabolites are hardly studied. Herein, we investigated the bioactive metabolites, phytochemicals, and antioxidant properties of fruits, sprouts (9-day-old), and mature tissue (5-week-old) of anise under laser irradiation treatment (He-Ne laser, 632 nm). Laser treatment increased biomass accumulation of both anise sprouts and mature plants. Bioactive primary (e.g., proteins and sugars) and secondary metabolites (e.g., phenolic compounds), as well as mineral levels, were significantly enhanced by sprouting and/or laser light treatment. Meanwhile, laser light has improved the levels of essential oils and their related precursors (e.g., phenylalanine), as well as enzyme activities [e.g., O–methyltransferase and 3-Deoxy-D-arabino-heptulosonate-7-phosphate synthase (DAHPS)] in mature tissues. Moreover, laser light induced higher levels of antioxidant and anti-lipidemic activities in sprouts as compared to fruits and mature tissues. Particularly at the sprouting stage, anise was more responsive to laser light treatment than mature plants.
