The aim of the study was the monitoring of six biogenic amines (histamine, tyramine, phenylethylamine, tryptamine, putrescine, and cadaverine) and two polyamines (spermidine and spermine) in 112 samples of dairy products purchased in the Czech Republic, namely in 55 cheeses made in small-scale farms and in 57 fermented dairy products. The products were(More)
The aim of the study was to explore production of seven biogenic amines (phenylethylamine, histamine, cadaverine, tyramine, putrescine, spermine and/or spermidine) by selected staphylococci and enterococci. Thirty three enterococcal strains isolated from rabbit meat (Oryctolagus cuniculus f. domesticus) and 21 staphylococcal strains isolated from intestinal(More)
The aim of the study was to compare, within 3-week cold storage, the content of eight biogenic amines (BA) and the development of microflora in different parts of bodies (breast and thigh muscles and liver) of farm pheasants and pheasants hunted in the wild. Killed and untreated bodies of pheasants were stored hanging in an air-conditioned chamber at a cold(More)
Highly undesirable microbial contaminants of processed cheese are endospore-forming bacteria of the genera Bacillus and Clostridium. Survival of Bacillus subtilis, B. cereus, Clostridium butyricum and C. sporogenes was examined in model processed cheese samples supplemented with monoacylglycerols. In processed cheese samples, monoacylglycerols of(More)
Hospital environments are typically large, and even healthy individuals can need a navigation map. When we consider the combination of stress, concerns about health and convalescence, age and other factors that can affect hospital patients, it is clear that navigation can be a problem, and that assistance may be required. This paper focuses on the technical(More)
The aim of this study was to monitor the antibacterial effect of seven phosphate salts on selected strains of Gram-negative and Gram-positive bacteria, which could be considered responsible for food-borne diseases (Bacillus cereus, Bacillus subtilis, Enterococcus faecalis, Micrococcus luteus, Staphylococcus aureus, Citrobacter freundii, Escherichia coli,(More)
The effect of pH (6, 7 and 8) and glucose, galactose and fructose content (0.00, 0.25, 0.50, 0.75 and 1.00% w/v) on growth and decarboxylase activity of Serratia marcescens was evaluated. Nutrient broth with 0.2% w/v of ornithine was used for the cultivation of bacteria. Biogenic amine production was determined using the ion-exchange chromatography with(More)
