Exopolysaccharides produced by lactic acid bacteria of kefir grains.
A Lactobacillus delbrueckii subsp. bulgaricus HP1 strain with high exopolysaccharide activity was selected from among 40 strains of lactic acid bacteria, isolated from kefir grains. By associating the Lactobacillus delbrueckii subsp. bulgaricus HP1 strain with Streptococcus thermophilus T15, Lactococcus lactis subsp. lactis C15, Lactobacillus helveticus MP12, and Sacharomyces cerevisiae A13, a ...
متن کاملLactic Acid Bacteria and Yeast from Kefir
Nippon Eiyo Shokuryo Gakkaishi (J. Jpn. Soc.Nutr. Food Sci.) 47, 55~59 (1994) Lactic acid bacteria (3 strains of cocci and 10 strains of bacilli) and lactose-fermenting yeasts (18 strains) were isolated from a 24 h cultured of kefir milk. The lactococci and yeasts were identified as Streptococcus lactis and Kluyveromyees marxianus var. marxianus, respectively. The lactobacilli were of the heter...
متن کاملProbiotic potential of selected lactic acid bacteria strains isolated from Brazilian kefir grains.
A total of 34 lactic acid bacteria isolates from 4 different Brazilian kefir grains were identified and characterized among a group of 150 isolates, using the ability to tolerate acidic pH and resistance to bile salts as restrictive criteria for probiotic potential. All isolates were identified by amplified ribosomal DNA restriction analysis and 16S rDNA sequencing of representative amplicons. ...
متن کاملRole of Lactic Acid Bacteria-Myeloperoxidase Synergy in Establishing and Maintaining the Normal Flora in Man
Lactic acid bacteria (LAB) are incapable of cytochrome synthesis and lack the heme electron transport mechanisms required for efficient oxygen-based metabolism. Consequently, LAB redox activity is flavoenzyme-based and metabolism is fermentative, producing lactic acid, and in many cases, hydrogen peroxide (H2O2). Despite this seeming metabolic limitation, LAB dominate in the normal flora of the...
متن کاملMetabolic activity and symbiotic interactions of lactic acid bacteria and yeasts isolated from water kefir.
Water kefir is a mildly sour and alcoholic drink fermented by a stable microbial multispecies community. With its high sugar content and low amino acid concentration water kefir medium represents a demanding habitat. In this ecological niche only well adapted microorganisms which are fit to the consortium are able to grow and mutually provide essential nutrients. The synergism between main repr...
