The present study was conducted to investigate the ability of Saccharomyces cerevisiae RC016 (Sc)-based feed additive reduce liver toxicity, residual aflatoxin B1 (AFB1) levels and influence intestinal structure in broiler chickens fed chronic B1-contaminated diets. A total 100 one-day-old male commercial line (Ross) were divided into 4 treatments, with 5 pens per treatment pen. Birds randomly assigned which namely 1 (T1), control diet (CD); T2, CD + Sc at g/kg; T3, AFB1 μg/kg; T4, g/kg...

Abstract Bioprospection of natural compounds by next-generation probiotic strains holds immense promise for promoting beneficial effects on both animal and human health. The aim the present work was to study antimicrobial activity lactic acid bacteria postbiotics multidrug resistant pathogenic Salmonella sp. Escherichia coli. Moreover, short-chain fatty acids (SCFA) production antioxidant were evaluated. Additionally, potential industrial-scale ensure feasibility scalability postbiotic-based...

The R6-5 plasmid-specified outer membrane protein, TraT has previously been shown to mediate resistance bacterial killing by serum. Colony hybridization with a 700 bp DNA fragment carrying most of the traT gene was used examine prevalence in Gram-negative bacteria, particularly strains Escherichia coli, isolated from clinical specimens. found isolates E. Salmonella, Shigella and Klebsiella, but not Pseudomonas, Aeromonas or Plesiomonas, nor few Enterobacter, Proteus, Acinetobacter,...

Arachis hypogaea L. (peanut) skin is a potential source of natural antioxidants, and several studies have suggested the possibility producing functional ingredients from this by-product food industry. This investigation examined possible toxic effects peanut polyphenolic extract (PSE) its antioxidant properties using in vitro studies. PSE main component quercetin (QE) did not present any cytotoxicity on normal epithelial cells, rat ileum cells (IEC-18), monkey kidney (Vero) or human...

The photosensitized isomerization reaction of the natural cis carotenoid bixin (methyl hydrogen 9'-cis-6, 6'-diapocarotene-6, 6'-dioate) with rose bengal or methylene blue as sensitizer in acetonitrile/methanol (1:1) solution was studied using UV-vis spectroscopy, high-performance liquid chromatography (HPLC), and time-resolved spectroscopic techniques, such laser-flash photolysis singlet oxygen phosphorescence detection. In both N(2)- air-saturated solutions, main product formed...

The influence of the medium heterogeneity upon bimolecular rate constants for physical quenching, kq, and chemical kr, singlet molecular oxygen O2(1Δg) by seven natural three synthetic carotenoids (CAR) with different substituent patterns was studied in a reverse micelle system sodium bis(2-ethylhexyl)sulfosuccinate, hexane water. Because generated inside water pools micelles photosensitization water-soluble dye rose bengal CAR are mainly located external pseudophase, quenching process...

Microcapsules of gum arabic or maltodextrin 20DE containing antioxidant molecules (AOx), for example, carotenoids and tocopherol derivatives, were prepared by the spray-drying technique. The properties these microcapsules evaluated several techniques, such as dynamic light scattering, scanning electronic microscopy, steady-state time-resolved fluorescence spectroscopy microencapsulated pyrene. quenching photochemically generated singlet molecular oxygen (1O2) AOx in homogeneous solvents well...

Riboflavin (Rf)-mediated photosensitized degradation of vitamins A and D3 in skimmed milk under illumination with a white fluorescence lamp was studied by using the HPLC technique. The both followed first-order kinetics, temperature effect on observed photodegradation rate constant allowed determination activation energy Ea as being 4 16 kcal/mol for D3, respectively. addition lycopene microencapsulated spray-drying gum arabic−sucrose (8:2) mixture (MIC) produced reduction ca. 45% vitamins....
