The name includes morphology, a rod-shaped (bacillus shape) bacterium with a width of 2.0 to 4.0μm and length of 0.8 to 1.0μm. Strains of L. paracasei have been isolated from a variety of environments including dairy products, plants or plant fermentations, and from the human and animal gastrointestinal tracts.
Minoru Shirota (代田 稔, Shirota Minoru, April 23, 1899 – March 10, 1982) was a Japanese microbiologist. In the 1930 Shirota identified a strain of lactic acid bacteria that is part of normal gut flora that he originally called Lactobacillus casei Shirota, which appeared to help contain the growth of harmful bacteria in the gut.

Lacticaseibacillus casei is an organism that belongs to the largest genus in the family Lactobacillaceae, a lactic acid bacteria (LAB), that was previously classified as Lactobacillus casei. [1] This bacteria has been identified as facultatively anaerobic or microaerophilic, acid-tolerant, non-spore-forming bacteria.
Yakult's ingredients are water, skimmed milk, glucose-fructose syrup, sucrose, natural flavors , and live Lacticaseibacillus casei Shirota bacteria. [1] [2] The strain was originally classified as being Lactobacillus casei. [1] Yakult is prepared by adding glucose to skimmed milk and heating the mixture at 90 to 95 °C for about 30 minutes ...
The Lactobacillaceae are a family of lactic acid bacteria. [3] It is the only family in the lactic acid bacteria which includes homofermentative and heterofermentative organisms; [4] in the Lactobacillaceae, the pathway used for hexose fermentation is a genus-specific trait.
Lacticaseibacillus rhamnosus GR-1 was originally found in the urethra of a healthy female and is nowadays a model strain for vaginal probiotics. A genome comparison between L. rhamnosus GG and L. rhamnosus GR-1 shows that GR-1 lacks spaCBA-encoded pili, an important adhesin in L. rhamnosus GG adhesion to the intestinal epithelial cells. [29]
A 2002 meta-analysis that included five double-blind trials examining the short-term (2–8 weeks) effects of a yogurt with probiotic strains on serum cholesterol levels found little effect of 8.5 mg/dL (0.22 mmol/L) (4% decrease) in total cholesterol concentration, and a decrease of 7.7 mg/dL (0.2 mmol/L) (5% decrease) in serum LDL concentration.
