Lacticaseibacillus paracasei is a gram-positive, homofermentative, non-spore forming microorganism. [11] As Lc. paracasei is homofermentative, lactic acid is produced as the main product of hexose metabolism while lactate and acetate are produced from pentoses.
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.
Among the best-documented probiotic strains of L. casei, L. casei DN-114001 (Actimel/DanActive) and L. casei Shirota have been extensively studied [19] and are widely available as functional foods. The genomes of these two strains have been sequenced from commercial yogurt, re-designated "LcA" and "LcY" respectively.

Improving preventative care across the country. In the Lower 48, cervical cancer deaths are higher in states with large uninsured populations and a high percentage of Black residents.
The lactic acid bacteria (LAB) are either rod-shaped (), or spherical (), and are characterized by an increased tolerance to acidity (low pH range).This aspect helps LAB to outcompete other bacteria in a natural fermentation, as they can withstand the increased acidity from organic acid production (e.g., lactic acid).
The ionised particles are then accelerated, and spectral peaks recorded, producing an expression profile, which is capable of differentiating specific bacterial strains after being compared to known profiles. [26] This includes, in the context of antibiotic susceptibility testing, strains such as beta-lactamase producing E. coli. [9]
Lacticaseibacillus rhamnosus (previously Lactobacillus rhamnosus [1]) is a bacterium that originally was considered to be a subspecies of L. casei, but genetic research found it to be a separate species in the L. casei clade, which also includes L. paracasei and L. zeae.
