Nitrites commonly found in food, especially in fermented vegetables, are potential carcinogens. Therefore, limiting nitrites in food is critically important for food safety. A Lactobacillus strain (Lactobacillus sp. DMDL 9010) was previously isolated from fermented vegetables by our group, and is not yet fully characterized. A number of phenotypical and genotypical approaches were employed to c...
At the 1920 meeting of the Society of American Bacteriologists a paper, published only in abstract form (Sherman, 1921), presented some characteristics of Lactobacillus bulgaricus, differentiating this organism from certain other lactobacilli. Eighteen cultures of Lactobacillus bulgaricus were then studied; a number of Lactobacillus casei; a few cultures from feces, assumed to belong to the Lac...
facultative heterofermentative lactobacilli (fhl) are responsible for enhancing unique flavour properties in traditional dairy products such as lighvan cheese through biochemical mechanisms. in addition to saving domestic genetic resources, industrial production of semi-traditional dairy products is one of the major objectives of non starter microflora identification in indigenous dairy product...
We previously discovered a symbiotic lactic acid bacterial (LAB) microbiota in the honey stomach of the honeybee Apis mellifera. The microbiota was composed of several phylotypes of Bifidobacterium and Lactobacillus. 16S rRNA gene sequence analyses and phenotypic and genetic characteristics revealed that the phylotypes isolated represent seven novel species. One grouped with Lactobacillus kunke...
One approach to deliver therapeutic agents, especially proteins, to the gastro-intestinal (GI) tract is to use commensal bacteria as a carrier. Genus Lactobacillus is an attractive candidate for use in this approach. However, a system for expressing exogenous proteins at a high level has been lacking in Lactobacillus. Moreover, it will be necessary to introduce the recombinant Lactobacillus int...
background: lactic acid bacteria play a key role in sourdough fermentation. lactobacilli are the most important group of lactic acid bacteria in sourdough. therefore, the main objective of this study was to identify lactobacillus strains in iranian traditional wheat sourdoughs as a basis for further studies on the technological applications in the production of typical breads. methods: fourteen...
Puba or carimã is a Brazilian staple food obtained by spontaneous submerged fermentation of cassava roots. A total of 116 lactobacilli and three cocci isolates from 20 commercial puba samples were recovered on de Man, Rogosa and Sharpe agar (MRS); they were characterized for their antagonistic activity against foodborne pathogens and identified taxonomically by classical and molecular methods. ...
A rapid and reliable PCR-based method for distinguishing closely related species within two groups of lactobacilli is described. Primers complementary to species-specific sequences in the 16S/23S rDNA spacer regions were designed after sequencing and sequence comparison of the spacer regions of 32 strains. The strains belong to two groups of closely related Lactobacillus species; one composed o...

BACKGROUND & AIMS The effects of probiotics on gut dysfunction in postinfective irritable bowel syndrome are unknown. We tested whether probiotics influence persistent muscle hypercontractility in mice after recovery from infection with Trichinella spiralis and analyzed the underlying mechanisms. METHODS Mice were gavaged with Lactobacillus paracasei, Lactobacillus johnsonii, Bifidobacterium ...
