To improve the quality and safety of food products, there is a need in the food industry for a reliable method for simultaneously monitoring multiple bacterial strains. Microarray technology is a high-throughput screening approach that can provide an alternative for bacteria detection. A total of 164 bacteria-specific probes were designed from 16S rRNA gene… (More)
Molecular chaperone DnaK of halophilic Tetragenococcus halophilus JCM5888 was characterized under salinity conditions both in vitro and in vivo. The dnaK gene was cloned into an expression vector and transformed into Escherichia coli. The DnaK protein obtained from the recombinant E. coli showed a significantly higher refolding activity of denatured lactate… (More)
Lactococcus garvieae BCC 43578 produces a novel class II bacteriocin, garvieacin Q (GarQ), 70 amino acids in length and containing a 20-amino-acid N-terminal leader peptide. It is cleaved at the Gly-Gly site to generate the mature GarQ (5,339 Da), which is especially inhibitory against Listeria monocytogenes ATCC 19115 and other L. garvieae strains.
Forty-one tetrad-forming halophilic lactic acid bacteria were isolated from 7 kinds of fermented foods in Thailand. All the isolates were identified as the genus Tetragenococcus by their phenotypic characteristics. On the basis of 16S rRNA gene restriction analysis using MboI and AluI and 16S rRNA gene sequence analyses, 41 isolates could be divided into… (More)
Biogenic amines are of concern for sausage due to their toxicological effects on nervous, blood pressure, gastric and intestinal systems. In this study, the influence of raw pork meat quality and starter culture inoculation on biogenic amines accumulation in Nham, a Thai traditional fermented pork, were studied. Before Nham processing, pork meat was stored… (More)
Tetragenococcus halophila originally isolated from soy sauce is a halophilic lactic acid bacterium which can grow under 4 M sodium chloride. T. halophila chaperonin composed of a core moiety of chaperonin 60 (cpn60) and a lid moiety of chaperonin 10 (cpn10), is thought to contribute to host halotolerant capability. In this report, we reconstituted and… (More)
