Lactic acid bacteria, especially Gram positive bacteria of the genus Lactobacillus
, possess a high probiotic potential, and naturally inhabit the gut of mammals and birds , .
In all studies, the most widely explored bacteria are from the genus Lactobacillus
, of which, Lactobacillus casei is the top ranked strain.
Studies have shown that the members of the genus Lactobacillus
are intrinsically tolerant to low pH (Tannock, 2004), and their bile tolerance is due to the presence of bile salt hydrolase enzymes that specifically hydrolyze bile salts (McAuliffe et al., 2005).
In 2015, Terai et al selected, from dental plaque and tongue of healthy individuals, bacteria of the genus Lactobacillus
and Streptococcus which did not produce volatile sulfur compounds (VSCs) or water-insoluble glucans, with high antibacterial activity against caries and periodontitis-causing bacteria as well as high activity of adherence to oral epithelial cells and hydroxyapatite in vitro.
Interestingly, probiotic LGG supplementation prevents alcohol-induced dysbiosis of the intestinal microbial community, and leads to an increase in Firmicutes, particularly of the genus Lactobacillus
. Furthermore, in an U.S.
Study of the biological properties of new strains of the genus Lactobacillus
. General Biology.
The genus Lactobacillus
is a heterogeneous group of LAB with important application in food and feed fermentation.
The researchers demonstrated that bacteria in the gut, particularly members of the genus Lactobacillus
, promote the growth of host epithelial cells and that this is essential for maintaining homeostasis in the intestinal system.
From 21 days of fermentation we isolated only bacteria of the genus Lactobacillus
The root seemed to promote the proliferation of the thermophilic group of bacteria with 56% of the Genus Lactobacillus
in TO and 34% in LO respectively, as shown in Table 3.
A general recommendation is to look for probiotic products containing bacteria in the genus Lactobacillus
or Bifidobacterium; however, many species and strains of these bacteria exist, and finding the right one may take trial and error.
(any Lactobacillus) was detected by PCR in all women irrespective of Nugent score, the most common species were L.
. En: Sneath PHA, Mair NS, Sharpe, MF, Holt JG.
Among the genus Lactobacillus
, the identified species and their respective strains include Lb.
Clinical trials have shown that bacteria of the genus Lactobacillus
, in particular, when consumed orally daily are especially effective at establishing and maintaining healthy vaginal microflora.
