In this research, the survival of probiotic microorganisms in yogurts stored at room temperature (cold chain interruption conditions) was studied. Milk inoculated with yogurt bacteria (mixed culture of Streptococcus thermophilus and Lactobacillus delbrueckii ssp. bulgaricus) and a single probiotic culture (L. acidophilus LA-5 or Bifidobacterium lactis Bb- 12 or L. rhamnosus HN001 or L. paracase...
materials and methods lactic acid bacteria isolated from spoiled fruits and vegetables and grown in mrs medium were screened against multi-drug-resistant candida albicans, klebsiella pneumoniae, pseudomonas aeruginosa, escherichia coli, and enterococcus fecalis. results fifty-four lactic acid bacteria were isolated from spoiled fruits and vegetables, of which 11 gram-positive and catalase-negat...
Probiotic bacteria have been shown to modulate immune responses and could have therapeutic effects in allergic and inflammatory disorders. However, little is known about the signalling pathways that are engaged by probiotics. Dendritic cells (DCs) are antigen-presenting cells that are involved in immunity and tolerance. Monocyte-derived dendritic cells (MoDCs) and murine DCs are different from ...
Fermentation of fructooligosaccharides (FOS) and other oligosaccharides has been suggested to be an important property for the selection of bacterial strains used as probiotics. However, little information is available on FOS transport and metabolism by lactic acid bacteria and other probiotic bacteria. The objectives of this research were to identify and characterize the FOS transport system o...
In the present study, a wild-type Lacticaseibacillus paracasei SP5 (L. SP5) potential probiotic strain (previously isolated from kefir grains) was applied for 1-day fermentation of an apple–orange–carrot mixed juice. After fermentation, juice refrigerated in cold storage at 4 °C, and microbiological stability, characterization volatiles, physicochemical properties (pH, total titratable acidity ...
This study identified the odor-active compounds and the qualitative characteristics of doughs from "ancient" grains flours fermented by lactic acid bacteria. For this purpose doughs made with quinoa and Kamut® flours have been produced and inoculated with strains belonging to the species Lactobacillus paracasei, Lactobacillus plantarum and Lactobacillus brevis and compared with fermented doughs...
Lactic acid bacteria, including lactobacilli, enterococci, leuconostoc and weissella species isolated from Iranian traditional fermented camel milk (Chal) were assessed for the incidence of virulence determinants (gelE, efaAfm, efaAfs, ace, espfs, cylM, cylA and cylB), sensitivity to various antibiotics and virulence phenotypes. The incidence of virulence genes was determined by polymerase cha...
The exopolysaccharide secreted by Lacticaseibacillus paracasei subsp. SS-01 strain (LP-EPS) is isolated and purified from yogurt. It a polysaccharide with branched multi-stranded structure, which exists in smooth rod-like or cloud-like state, possesses good thermal stability molecular weight of 49.68 kDa (±4.436%). LP-EPS shows high antioxidant capacity, anti-inflammatory anti-sensitizing activ...
