We identified the lactic acid bacteria within rye sourdoughs and starters from four bakeries with different propagation parameters and tracked their dynamics for between 5-28 months after renewal. Evaluation of bacterial communities was performed using plating, denaturing gradient gel electrophoresis, and pyrosequencing of 16S rRNA gene amplicons. Lactobacillus amylovorus and Lactobacillus frum...

Lactobacillus helveticus strain H10 was isolated from traditional fermented milk in Tibet, China. We sequenced the whole genome of strain H10 and compared it to the published genome sequence of Lactobacillus helveticus DPC4571.

Lactobacillus helveticus R0052 is a commercially available strain that is widely used in probiotic preparations. The genome sequence consisted of 2,129,425 bases. Comparative analysis showed that it was unique among L. helveticus strains in that it contained genes encoding mucus-binding proteins similar to those found in Lactobacillus acidophilus.

Nunu, a spontaneously fermented yoghurt-like product, is produced and consumed in parts of West Africa. A total of 373 predominant lactic acid bacteria (LAB) previously isolated and identified from Nunu product were assessed in vitro for their technological properties (acidification, exopolysaccharides production, lipolysis, proteolysis and antimicrobial activities). Following the determination...

Lactobacillus helveticus is a lactic acid bacterium used traditionally in the dairy industry, especially in the manufacture of cheeses. We present here the 2,141,841-bp draft genome sequence of L. helveticus strain ATCC 12046, a potential starter strain for improving cheese production.

Strain R0052, isolated from a North American dairy starter culture, was initially identified as Lactobacillus acidophilus based on phenotypic analyses. However, upon sequencing the 16S rRNA gene, it became clear that the isolate was very highly related to Lactobacillus suntoryeus, Lactobacillus helveticus and Lactobacillus gallinarum, as similarities ranging from 99.3 to 99.8 % were observed. A...

the lactic acid bacteria in 9 samples of the fermented camel milk, chal, taken from rural area and retail markets were identified on the basis of their physiological and morphological properties. from the samples, 93 lab species including, 64 bacillus (68.8%), 8 cocci 8.6%), 11 coccobacillus (11.83%), 2 streptococcus (2.15%) and 8 tetrade (8.6%) were identified. among the lactobacillus species,...

The S-layer-encoding genes of 21 Lactobacillus helveticus strains were characterized. Phylogenetic analysis based on the identified S-layer genes revealed two main clusters, one which includes a sequence similar to that of the slpH1 gene of L. helveticus CNRZ 892 and a second cluster which includes genes similar to that of prtY. These results were further confirmed by Southern blot hybridizatio...
