lactic acid bacteria are characterized as gram-positive, usually non-motile, non-sporulating bacteria that produce lactic acid as a major or sole product of their fermentative metabolism. in this study, the presence of lactobacilli were investigated in the intestines of beluga ( huso huso) and persian sturgeon ( acipenser persicus ), inhabiting caspian sea. the obtained data showed that various...

Intestinal microflora constitutes a symbiotic ecosystem in permanent equilibrium, composed mainly of anaerobic bacteria. However, such equilibrium may be altered by daily conditions as drug use or pathologies interfering with intestinal physiology, generating an unfavorable environment for the organism. Besides, there are factors which may cause alterations in the intestinal wall, creating the ...

Earlier work had shown that a collection of anaerobic bacteria, in conjunction with facultative anaerobes, may be implanted into germfree mice, thereby rendering the animals "normal" with respect to a variety of parameters tested. The present experiments indicate that a different collection of anaerobic bacteria, isolated from the cecum of normal mice, was necessary to convert germfree mice to ...

BACKGROUND Kiwifruit is high in pectic polysaccharides and dietary fiber. This study aimed to find out how the ingestion of kiwifruit will affect intestinal microbiota populations, namely Lactobacillus, Bacteroides, Clostridium, Bifidobacterium, and Enterococcus. METHODS Freeze dried kiwifruit (equivalent of two fresh kiwifruits) was given to each of the six subjects daily for four days. Faec...

Mammalian intestinal surfaces are in constant and intimate contact with a vast consortium of indigenous commensal bacteria. As a result, gut epithelia have evolved an array of strategies for limiting bacterial invasion into deeper tissues, helping to preserve the mutually beneficial nature of intestinal host-microbial relationships. In this review, we discuss a growing body of evidence indicati...

A total of 240, one-day-old quail chicks (Coturnix coturnix japonica) were used to study the effects of Artichoke leaf meal (ALM) and vitamin E in diet on growth performance, ileal microbial populations and intestinal morphology in a 42-d trial. This experiment was performed as a completely randomized design with 4 replicates of 15 quails each, using a 4 × 2 factorial arrangement with diet and ...

in this study, symbiotic yog-ice (rozen yogurt) was produced that was inoculated with different levels of inulin(0,2.5 amd 5%)as prebiotic compound and lactobacillus casei as probiotic bacteria in two types; free and encapsulated with sodium algint-whey protein concentration for low fat yog-ice cream.the survivability of this probiotic bacteria was evaluated under simulated gastro-intestinal co...

Klite, P. D. (Middle America Research Unit, Balboa Heights, Canal Zone). Intestinal bacterial flora and transit time of three neotropical bat species. J. Bacteriol. 90:375-379. 1965.-Quantitative studies on the intestinal bacterial flora of three neotropical bat species revealed the following average bacterial populations: Molossus major, 10(4.8) bacteria per intestinal contents; Carollia persp...

Chitosan was used for nanoencapsulation of Lactobacillus acidophilus as probiotic bacteria. In vitro experiments were done with the objective of investigating the survival of the bacteria cells in gastro-intestinal conditions. The results demonstrated that the size of chitosan nanoparticles noticeably increases by increasing chitosan concentration from 0.05 to 0.5 g/mL. Encapsulation of the cel...
