This paper describes the physicochemical study of adsorption dysprosium (Dy3+) in aqueous solution onto two types activated carbons synthesized from spent coffee ground. Potassium hydroxide (KOH)-activated carbon is a microporous material with specific Brunauer-Emmett-Teller (BET) surface area 2330 m2·g-1 and pores diameter 3.2 nm. Carbon water vapor N2 solid mesoporous, 5.7 nm 982 m2·g-1. A significant dependence capacity on pH was found, but it does not significantly depend concentration...

Shiga toxin producing Escherichia coli (STEC), Salmonella spp., and Yersinia species was investigated in humans, animals, foods San Luis, Argentina. A total of 453 samples were analyzed by culture PCR. The antimicrobial susceptibility all the strains studied, genomic relationships among isolates same determined PFGE, potencial virulence Y. enterocolitica analyzed. showed higher prevalence (9/453, 2.0%, 95% CI, 0.7–3.3%) than STEC (4/453, 0.9%, 0–1.8%) spp. (3/453, 0.7%, 0–1.5%). intermedia...
ABSTRACT Decimal reduction times ( D values) and z values for a three‐strain cocktail of Yersinia enterocolitica O:9 in three heat‐treated liquid egg products (whole eggs, yolks whites) were determined. Products inoculated at final concentration 2 × 10 7 cfu/mL heated capillary tubes to temperatures ranging from 51C 64C various time intervals. ranged 0.06 (64C) 11.30 min (55C) yolk, 0.058 11.29 whole eggs 0.39 (57C) 9.88 (51C) white. Thermal inactivation curves yielded 4.20C eggs), 4.51C...
Abstract Yersinia enterocolitica is associated with human clinical manifestations. In this study, the bioserotype distribution, virulence potential, antimicrobial susceptibility, and genomic diversity of Y. isolates recovered from Argentina Chile were assessed. Eight Chilean 22 Argentine (7) animal feces (3), foods (18) wastewater (2) analyzed. They belonged to bioserotypes B2 O:9 (9), B1A O:5 (8), O:41,42‐41,43 B4 O:3 (3) O:7,8‐8‐8,19 (2). Autoagglutination (AA), Ca 2+ ‐dependent growth at...
Yersinia enterocolitica is a food-borne pathogen that causes gastroenteritis with occasional postinfection sequels. This study was aimed to determinate the pathogenic potential, antimicrobial susceptibility, and genomic relationships of Y. strains different bioserotypes (B/O) isolated from foods human samples in San Luis, Argentina. Strains obtained by culture were bioserotyped characterized phenotypic genotypic virulence markers, pulsed-field gel electrophoresis (PFGE). detected 9.2% 380...
Abstract Shiga toxin‐producing Escherichia coli (STEC) in meat products was studied by four procedures which combined enrichment, immunomagnetic separation (IMS), plating, and a stx screening polymerase chain reaction. A total of 167 samples (57 ground beef, 58 fresh sausages, 52 precooked sausages) were collected from retail markets San Luis, Argentina. The number ‐positive represented 11.4% the (19/167) distributed as follows: seven for raw beef (12.3%), six sausages (11.5%), (10.3%). stx‐...
Aims: To determine the effectiveness of sucrose monolaurate (SML) and monocaprate (SMC), alone in combination with ethylenediaminetetraacetic acid (EDTA), propionic (PA) or citric (CA) reducing mesophilic aerobic bacteria (MAB) Yersinia enterocolitica O:9 populations on eggshells their damage potential microstructure shell cuticle. Methods Results: Uninoculated eggs submerged a solution Y. were immersed solutions various treatments. MAB counts surface carried out before after treatment....
