The influence of growth parameters on the fermentative production of a nisin-like bacteriocin by Lactococcus lactis subsp. lactis A164 isolated from kimchi was studied. The bacteriocin production was greatly affected by carbon and nitrogen sources. Strain A164 produced at least 4-fold greater bacteriocin in M17 broth supplemented with lactose than other(More)
A Gram-stain-negative, non-motile, aerobic and rod-shaped bacterium, designated strain MME-001T, was isolated from the tidal flat of Muui-do in the Republic of Korea. Phylogenetic trees based on the 16S rRNA gene sequence showed that strain MME-001T belonged to the genus Pseudoruegeria in the family Rhodobacteraceae and that it shared the highest 16S rRNA(More)
A gram-positive, catalase-negative, non-sporulating, facultatively anaerobic, short rod-shaped bacterium, with cells measuring 0.3-0.5 x 1-2 microm and designated strain CHJ3T, was isolated from partially fermented kimchi, a traditional Korean fermented vegetable food. The strain produced CO2 gas, D-lactate from glucose and dextran from sucrose and(More)
A novel, red-pigmented, pleomorphic and short rod-shaped haloarchaeon, designated B8T, was isolated from a salt-fermented seafood. Strain B8T was found to be able to grow at 20–45 °C, in the presence of 15–30 % (w/v) NaCl and at pH 7.0–9.0. The optimum requirements were found to be a temperature range of 35–40 °C, pH 8.0 and the presence of 25 % NaCl. The(More)
A Gram-positive, aerobic, non-motile and extremely halophilic bacterial strain, designated K9T, was isolated from kimchi, a Korean fermented food. The strain was observed as endospore-forming rod-shaped cells showing oxidase and catalase activity. It was found to grow at 10.0–30.0 % (w/v) NaCl (optimum, 15.0–20.0 %), pH 7.0–8.0 (optimum, pH 7.5) and 15–40(More)
Nisin Z production in Lactococcus lactis subsp. lactis A164 was improved by introducing multicopy genes, nisZ, nisRK, or nisFEG, involved in nisin biosynthesis into A164 strain. A similar growth profile was obtained from all strains tested. However, the cells expressing nisRK produced 25,000 AU nisin Z ml−1 compared to 16,000 AU ml−1 by the control strain.(More)
Flamingoes (Phoenicopterus spp.) whose plumage displays elegant colors, inhabit warm regions close to the ocean throughout the world. The pink or reddish color of their plumage originates from carotenoids ingested from carotenoid-abundant food sources, since flamingoes are unable to synthesize these compounds de novo. In this study, viable red-colored(More)
Protein functions are often revealed by their localization to specialized cellular sites. Recent reports demonstrated that swiprosin-1 is found together with actin and actin-binding proteins in the cytoskeleton fraction of human mast cells and NK-like cells. However, direct evidence of whether swiprosin-1 regulates actin dynamics is currently lacking. We(More)
A halophilic archaeal strain, designated CBA1105T, was isolated from non-purified solar salt. Strain CBA1105T was found to have three 16S rRNA genes, rrnA, rrnB and rrnC; similarities between the 16S rRNA gene sequences were 99.5–99.7 %. The phylogenetic analysis of the 16S rRNA gene sequences showed that strain CBA1105T forms a distinct clade with the(More)
Curcumin, a naturally occurring polyphenolic compound from Curcuma longa, has long been used in folk medicine as an antiinflammatory remedy in Asian countries. Endometriosis is a chronic gynecological inflammatory disorder in which immune system deregulation may play a role in its initiation and progression. A number of mediators, including cell adhesion(More)
