Probiotic characterization of lactic acid bacteria isolated from swine intestine
AIM A study was conducted with the objective to isolate probiotic microorganisms from swine intestine. MATERIALS AND METHODS In this study 63 isolates (24 caeca, 24 colon mucosal scrapings, and 15 rectal swab samples) were collected from Large White Yorkshire pigs. The isolates were inoculated and grown in de Man Rogosa Sharpe broth at 37°C with 5% CO2 for 48 h and subjected to morphological ...
متن کاملEnzymatic transformation of the major ginsenoside Rb1 to compound K by Weissella hellenica DC06
In the present study, the major ginsenoside Rb1 was transformed into the more pharmacologically active minor ginsenoside compound K (C-K) via the enzymatic activity of food grade Weissella hellenica DC06 isolated from kimchi, a traditional Korean fermented food. The transformation products were analyzed by TLC, HPLC, and LC/MS. Within 4 d of incubation, 100% of Rb1 was decomposed and converted ...
متن کاملEvaluation of Lactobacillus Species Isolated from Swine Intestine for their Probiotic Properties in Piglets
Intestinal mucosal scrapings (48) were collected from twelve, 6 month old, Large White Yorkshire pigs after slaughter. Isolates (23) that were gram positive rods, were alone subjected to physiological tests (growth at pH: 4.5, 9.5; temperature; 15, 45°C; and NaCl: 2, 6.5%), four isolates exhibited no growth at all conditions studied and were rejected. Biochemical tests on the remaining nineteen...
متن کاملGenome sequence of Lactobacillus salivarius GJ-24, a probiotic strain isolated from healthy adult intestine.
The draft genome sequence of Lactobacillus salivarius GJ-24 isolated from the feces of healthy adults was determined. Its properties, including milk fermentation activity and bacteriocin production, suggest its potential uses as a probiotic lactic acid bacterium and start culture for dairy products.
متن کاملCharacterization of a family 43 β-xylosidase from the xylooligosaccharide utilizing putative probiotic Weissella sp. strain 92.
In this work, we present the first XOS degrading glycoside hydrolase from Weissella, WXyn43, a two-domain enzyme from GH43. The gene was amplified from genomic DNA of the XOS utilizing Weissella strain 92, classified under the species-pair Weissella cibaria/W.confusa, and expressed in Escherichia coli. The enzyme is lacking a putative signal peptide and is, from a homology model, shown to be co...
