Cystic fibrosis is often associated with intestinal inflammation due to several factors, including altered gut microbiota composition. In this study, we analyzed the fecal among patients cystic of 10-22 years age, and compared findings age-matched healthy subjects. The participating included 14 homozygotes heterozygotes delF508 mutation, 2 presenting non-delF508 mutations. We used PCR-DGGE qPCR analyze presence bacteria, archaea sulfate-reducing bacteria. Overall, our confirmed disruption...
To assess the frequency of erythromycin- and tetracycline-resistant lactobacilli in Italian fermented dry sausages.We isolated colonies from 20 salami north Italy (Piacenza province) using selective medium supplemented with erythromycin or tetracycline; we determined minimum inhibitory concentration searched for selected tetracycline resistance genes. A total 312 were genetically ascribed to 60 different strains belonging seven Lactobacillus species. sakei, curvatus plantarum most frequently...
Sourdough fermentation of bakery products is a well-established and widespread technique to confer an added value the resulting food. In recent decades, gluten-free raw materials have gained more attention due diffusion food disorders such as coeliac disease, but, at same time, they present difficult manipulation scarce technological properties because absence gluten. For this reason, work was aimed selecting starter cultures for sourdough application that are isolated from sorghum flour....
Mealworm (MWP), migratory locust (LP), and house cricket (CP) are novel foods recently authorized by the European Commission. This work tested their powders as meat extenders at 5% inclusion in beef burgers. Insect were abundant phenolics, recording highest values LP (1184.9 μg/g). The sensory analysis highlighted a higher visual olfactory acceptability for MWP-burgers, followed CP- LP-burgers, whereas texture of cooked burgers remained unaffected. Following pan-cooking, MWP-burgers control...
The development of the microbial community involved in production process Italian dry sausage was investigated using physiological analysis and molecular techniques for strain typing taxonomical identification. A cycle followed collecting samples during 2 months ripening process. Microbiological allowed identification main bacterial groups responsible fermentation as lactobacilli coagulase-negative staphylococci. use a polymerase chain reaction-based technique typing, RAPD fingerprinting,...
Introduction Little is known about changes in intestinal microbiota during the important period of complementary feeding (weaning). This descriptive study investigated selected gut and markers permeability immune system breast fed infants period. Methods 22 healthy, exclusively (from birth to 4 months) with no antibiotic intake month prior study, were followed from 9 months age. Faecal saliva samples collected at start (V0) monthly intervals (V1—V5) for measurement selective (bifidobacteria,...
Methanogens commonly inhabit swine intestine. We analyzed the gut archaeal population by extracting DNA from feces of nine piglets. performed PCR to target V6–V8 region 16S rRNA gene. Subsequent denaturing gradient gel electrophoresis (DGGE) revealed presence Methanobrevibacter boviskoreani, which has not previously been identified in pigs. confirmed these data with a PCR-DGGE analysis mcrA gene, and subsequent sequencing. At 63 days old, only band fecal samples corresponded M. boviskoreani....
The nitric oxide synthase (NOS) activity was investigated in 35 staphylococcal strains from five distinct coagulase-negative staphylococci (CNS) species. NOS pathway is related with the production of oxide, potentially leading to formation nitrosomyoglobin imparting a pinkish-red colour fermented meats. employing both genotypic and phenotypic methods. Among studied, 16 were found contain gene encoding NOS, while 25 possessed arginase gene. Strains Staphylococcus saprophyticus, S. equorum,...
The extensive use of antibiotics as growth promoters, or their continued abusive misuse to cure prevent the onset bacterial infections occurs in intensive farming, may have played a pivotal role spread reservoirs antibiotic resistance (AR) among food-associated bacteria including pathogens representing risks human health. present study compares incidence tetracycline and erythromycin resistances lactic acid (LAB) coagulase negative staphylococci (CNS) from fermented products manufacturing...
The impact of duckweed extracts (DEs) on the shelf-life packaged beef burgers was evaluated through classical assays and untargeted metabolomics. Beef were formulated with an antioxidants-free control (CON), 1 g/kg sodium ascorbate (ASC), increasing levels a DEs, namely (DE1), 5 (DE5), 10 (DE10) g/kg, under modified atmosphere stored at 4 °C for 19 days. abundant in phytochemicals, determined no issues hygienic status product. DEs modulated redox status, being ineffective preserving...
