15 p, 953.8 KB Antimicrobial Activity and Prevention of Bacterial Biofilm Formation of Silver and Zinc Oxide Nanoparticle-Containing Polyester Surfaces at Various Concentrations for Use / Fontecha-Umaña, Fabio (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Ríos-Castillo, Abel Guillermo (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Ripolles-Avila, Carolina (Universitat Autònoma de Barcelona.

Food contact surfaces are primary sources of bacterial contamination in food industry processes. With the objective of preventing bacterial adhesion and biofilm formation on surfaces, this study evaluated the antimicrobial activity of silver (Ag-NPs) and zinc oxide (ZnO-NPs) nanoparticle-containing polyester surfaces (concentration range from 400 ppm to 850 ppm) using two kinds of bacteria, Gram-positive (Staphylococcus aureus) and Gram-negative (Escherichia coli), and the prevention of bacterial biofilm formation using the pathogen Listeria monocytogenes.

11 p, 1.5 MB Bactericidal efficacy of UV activated TiO2 nanoparticles against Gram-positive and Gram-negative bacteria on suspension Eficacia bactericida de nanopartículas de TiO2 activadas por luz UV contra bacterias Gram-positivas y Gram-negativas en suspensión / Ripolles-Avila, Carolina (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Martínez-García, María (Universitat Autònoma de Barcelona. Centre d'Innovació, Recerca i Transferència en Tecnologies dels Aliments (CIRTTA)) ; Hascoët, Anne-Sophie (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Rodríguez-Jerez, José Juan. (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments)
Two different TiO nanoparticles, NM101 and NM105, were evaluated against a range of Gram-positive (Staphylococcus aureus, Bacillus cereus, Lactobacillus casei, Lactobacillus bulgaricus, Lactobacillus acidophilus and Lactobacillus lactis) and Gram-negative (Salmonella enterica var. [...]

14 p, 1.9 MB Quantitative and Compositional Study of Monospecies Biofilms of Spoilage Microorganisms in the Meat Industry and Their Interaction in the Development of Multispecies Biofilms / Ripolles-Avila, Carolina ; García Hernández, Nerea ; Brayan H. Cervantes, Huamán ; Mazaheri, Tina ; Rodríguez-Jerez, José Juan (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments)
Food spoilage is a serious problem in the food industry, since it leads to significant economic losses. One of its main causes is the cross-contamination of food products from industrial surfaces. Three spoilage bacterial species which are highly present in meat and the gastrointestinal tract of chickens were selected: Pseudomonas fragi, Leuconostoc gasicomitatum, and Lactobacillus reuteri.

14 p, 2.6 MB Microbial ecology evaluation of an iberian pig processing plant through implementing sch sensors and the influence of the resident microbiota on Listeria monocytogenes / Hascoët, Anne-Sophie (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Ripolles-Avila, Carolina (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Guerrero-Navarro, Alfons Eduard (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Rodríguez-Jerez, José Juan (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments)
There is a whole community of microorganisms capable of surviving the cleaning and disinfection processes in the food industry. These persistent microorganisms can enhance or inhibit biofilm formation and the proliferation of foodborne pathogens. [...]

15 p, 1.6 MB The effects of dry, humid and wear conditions on the antimicrobial efficiency of triclosan-containing surfaces / Ríos-Castillo, Abel Guillermo (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Ripolles-Avila, Carolina (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments) ; Rodríguez-Jerez, José Juan (Universitat Autònoma de Barcelona. Departament de Ciència Animal i dels Aliments)
This study evaluated the effects of triclosan-containing polyester surfaces under various conditions at concentrations of between 400 ppm and 850 ppm. Staphylococcus aureus was chosen for the tests because it rapidly develops resistance to many antimicrobial agents. [...]
