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).
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.

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.
L. lactis cells are cocci that group in pairs and short chains, and, depending on growth conditions, appear ovoid with a typical length of 0.5 - 1.5 μm. L. lactis does not produce spores (nonsporulating) and are not motile . They have a homofermentative metabolism, meaning they produce lactic acid from sugars.
The U.S. Preventive Services Task Force released a draft recommendation advising against using vitamin D to prevent falls and fractures in people over 60. Pharmacist Katy Dubinsky weighs in.
Red light therapy for hair growth is FDA-approved and comes with very few side effects; and has been found in clinical studies to help encourage hair growth over time with regular use — every ...
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]
