Última Pseudomonas spp. and P. fluorescens: population in refrigerated raw milk Ciência Rural Almeida,Kelly Molin de; Bruzaroski,Samera Rafaela; Zanol,Daniel; Melo,Marcela de; Santos,Joice Sifuentes dos; Alegro,Lina Casale Aragon; Botaro,Bruno Garcia; Santana,Elsa Helena Walter de. ABSTRACT: Raw milk samples were collected from cooling tanks (after they cooled for 48 h) in five dairy farms and the corresponding bulk tank (bulk milk transportation, BMT) when they arrived to the industry. Routine physical chemical analyzes and quantification of psychrotrophic ( Pseudomonas spp. and P. fluorescens ) and aerobic mesophilic (AM) populations were performed. Only relative density and titratable acidity values for samples of milk from three farms were in agreement to the quality parameters required by law. In the BMT, only the protein content has not reached the minimum value established by law, and counting was performed for AM (>105 colony forming units (CFU) mL-1) and psychrotrophic bacteria (2.8x106CFU mL-1).

Fresh sausages are cured meat products that may be contaminated with Staphylococcus aureus during the manufacturing procedure, which is frequently related with inadequate handling practices. The use of nitrite in meat products has proven efficacy against Clostridium botulinum, and studies indicate that bactericidal action against S. aureus depends on factors that are intrinsic and extrinsic to the product. The objective of the present study was to evaluate the effect of nitrite concentration, and pH on S. aureus and psychrotrophic autochthone microbiota in fresh sausages stored at different times and temperatures. Fresh sausage were produced at nitrite concentrations 50, 150 and 200ppm and contaminated with S. aureus. The sausages were storage at...

In this study, inhibitory psychrotrophic lactic acid bacteria were isolated and investigated for future use in biopreservation of seafood products. Screening of 5575 colonies isolated from various seafood products resulted in the selection of 132 colonies presenting inhibitory properties. Among them, 52 isolates had characteristics of LAB and showed growth at 15 °C but not at 30 °C. The inhibition spectrum of these 52 isolates against 14 target strains (Gram-positive and -negative) showed inhibition of typical seafood spoiling and pathogenic bacteria and enabled the formation of seven interesting clusters. Sequencing of the 16S rRNA gene of a representative isolate from each cluster identified three Leuconostoc gelidum, two Lactococcus piscium, one...

La souche de Lactococcus sp. EU2241 a été isolée à partir de saumon emballé sous atmosphère modifiée. Elle a montré d'exellentes aptitudes à la biopréservation, augmentant la durée de vie de crevettes décortiquées sous vide, de saumon fumé et permettant d'inhiber de 2 logs la croissance de Listeria monocytogenes et Staphylococcus aureus sur du saumon fumé. L'objectif de ces travaux est de caractériser le comportement à basse température de cette souche, et d'identifier les mécanismes moléculaires intervenant dans sa capacité à s'adapter aux basses températures. Ce travail a été réalisé dans le cadre du projet intégré (IP) SEAFOODplus accordé par la commission européenne sous le numéro FOOD-CT-2004-506359.

Étude physiologique et moléculaire des mécanismes d’adaptation au froid ArchiMer Matamoros, Sebastien. Lactic acid bacteria strains were isolated from seafood products and clustered according to their inhibiting capacities against 14 food borne spoiling and pathogenic strains in order to develop applications in biopreservation. Most of the strains were identified as Leuconostoc gelidum and Lactococcus piscium. Detailed identification of one strain of the Lactococcus piscium strains suggests that it is a new specie. According to sensory analysis results, 2 strains belonging to the Leuconostoc gelidum specie were the most efficient for the enhancement of the shelf life of vacuum packed peeled and cooked shrimps. Similar results were obtained in cold smoked salmon with one strains of Lactococcus sp. A challenge test against three pathogenic strains (Listeria...
