Screening and Characterization of Potential Probiotic Lactic Acid Bacteria from Cultured Common Carp Intestine

Synbiotic (Biomin imbo) alters gut bacterial microflora of Russian sturgeon, Acipenser guldenstadti (Brandt & Ratzeburg, 1833) in a time-dependent pattern

“…Also, prebiotics are attributed to substrates that promote selectively the growth one or number of bacterial community in gut (Yazawa et al 1978;Roberfroid 1995, Mahious andOllevier 2005;Dimitroglou et al 2011). It was suggested that simultaneous use of probiotics and prebiotics under general title of Synbiotics can be more efficient than applying them alone (Chou et al 1991;Hagi and Hoshino 2009;Lauzon et al 2010a, b). Synbiotics exert almost their beneficial effects via various patterns including additivity, synergism and potentiation (Cerezuela et al 2011).…”

Genome Sequence of Lactococcus raffinolactis Strain 4877, Isolated from Natural Dairy Starter Culture

“…Here, we present the draft genome of Lactococcus raffinolactis strain 4877, isolated from a natural mesophilic dairy starter culture.T he mesophilic lactic acid bacterium Lactococcus raffinolactis is present in a wide range of environments, such as foods (meat, fish, milk, vegetable), animals, and plant materials (2,5,7,10). In the dairy environment, this species has been found in raw milks (cow, ewe, goat, and camel), natural dairy starter cultures, and a great variety of cheeses (3,4,6,8,9).…”

“…Subsequent use of these isolates in in vivo study as dietary probiotic gave successful results in challenge experiments against potential fish pathogens. The antimicrobial activity of the LAB isolates is thought to be multi factorial and to be due to the synergy effect of production of organic acids (acetic acid or lactic acid) and strain specific metabolites or non-lactic acid molecules, bacteriocins etc which serve as antibacterial agents to eliminate growth of competing microbes (Hagi and Hoshino, 2009). During preliminary screening for bacteriocin production, all the strains of L. plantarum along with L. pentosus SM35, L. fermentum SM51, L. brevis SM56, L. salivarius SM61, P. pentosaceus SM62, P. acidilactici SM64, P. acidilactici SM66 and all the strains of W. paramesenteroides, showed no zone of inhibition after addition of trypsin indicating the proteinaceous nature of the inhibitor.…”
