Lactobacillus acidophilus was first isolated from the human gastrointestinal tract in 1900 by Ernst Moro with the original name Bacillus acidophilus. Over time, there have been many changes to the methods for characterizing taxonomy of organisms, leading to the genus distinction of Lactobacillus in 1929.
Lactobacillus is a genus of gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non-spore-forming bacteria. [2] [3] Until 2020, the genus Lactobacillus comprised over 260 phylogenetically, ecologically, and metabolically diverse species; a taxonomic revision of the genus assigned lactobacilli to 25 genera (see § Taxonomy below).
The inhibitory substances produced by vaginal Lactobacillus is a primary factor in protecting the vaginal microbiota, with organic acids, bacteriocins, and hydrogen peroxide. These act synergistically against infection by pathogens. Not all Lactobacillus spp. and not all strains within one Lactobacillus species exhibit all 3 mechanisms. [13]
Multiple studies have shown that there is a significant difference in the survival rate of Lactobacillus and Bifidobacterium under refrigerated (4°C) and room temperature (25°C) storage conditions. At room temperature (25±1°C), the number of probiotics decreased by 5 to 6 logarithmic units (down to 1/100,000) after 90 days of storage.
Conversely, Lactobacillus fermentum and Saccharomyces boulardii have been found to be ineffective. [4] [failed verification] A combination of Lactobacillus plantarum and Lactobacillus rhamnosus has been found to be effective in suppressing bacterial overgrowth of abnormal gas producing organisms in the small intestine.
