It is a valuable and good food source with the ingredients it contains in milk, but if hygienic conditions are not ensured during milking, storage processing, diseases related to milk dairy products likely occur. More than 90% of these bacterial origin. B. cereus, found Bacillaceae family, significant contamination due presence psychrotrophic strains. In recent years, has been reported that con...

Although sheep meat has a small share of ?1.5 % the total production in EU, farming is great importance to rural development and environment. Enhancing quality lamb local breeds essential ensure both profitability for producers conservation endangered breeds. This study aimed (i) characterise evolution spoilage microorganisms refrigerated vacuum-packed from 10 farms housing 8 Portuguese, Spanis...

Tilapia (Oreochromis niloticus) is the most cultivated and consumed freshwater fish in Brazil. The present study aimed to evaluate microbiological quality of ice fresh tilapia samples commercialized Federal District. were tested for counts mesophilic psychrotrophic bacteria, determination total thermotolerant coliforms, Staphylococcus aureus presence Salmonella. Ice analyzed coliforms Escherich...

Psychrotrophic (6 203C) enrichment cultures from deep Pacific marine sediments and Alaskan tundra permafrost reduced ferric iron when using organic acids or H2 as electron donors. The representative culture W3-7 from the Pacific sediments grew fastest at 103C, which was 5-fold faster than at 253C and more than 40-fold faster than at 43C. Fe(III) reduction was also the fastest at 103C, which was...

Psychrotrophic bacteria are one of the significant microbes in chilled meat,pseudomonasis most predominant member this group. Pseudomonas could survive various ecological niches. In current study, we detect prevalence aeruginosa meat at Mosul city retailsandtheir antibiotics resistance profile. One hundred fifty samples from beef, mutton and chicken were collected aseptically cultivated. P. iso...

Exiguobacterium antarcticum B7 is extremophile Gram-positive bacteria able to survive in cold environments. A key factor to understanding cold adaptation processes is related to the modification of fatty acids composing the cell membranes of psychrotrophic bacteria. In our study we show the in silico reconstruction of the fatty acid biosynthesis pathway of E. antarcticum B7. To build the stoich...

The food-borne pathogen Listeria monocytogenes can grow in a wide range of temperatures, and several key virulence determinants of the organism are expressed at 37 degrees C but are strongly repressed below 30 degrees C. However, the impact of growth temperature on the ability of the bacteria to tolerate environmental stresses remains poorly understood. In other microorganisms, cold acclimation...

A dye reduction method was developed for estimating total aerobic and/or psychrotrophic bacterial counts in ground beef. The method is based on color changes in indicator disks placed on the meat surface.

The most important bacterial pathology currently occurring in Chilean freshwater salmon farming is the cold-water disease produced by the psychrotrophic bacteria Flavobacterium psychrophilum. The main aim of this study was to characterize the inhibitory activity of an antagonist strain on the formation of biofilms of a F. psychrophilum strain. The antagonistic strain Pseudomonas fluorescens FF4...
