Lactobacillus acidophilus (Neo-Latin 'acid-loving milk-bacillus') is a rod-shaped, Gram-positive, homofermentative, anaerobic microbe first isolated from infant feces in the year 1900. [1] The species is commonly found in humans, specifically the gastrointestinal tract and oral cavity as well as some speciality fermented foods such as fermented ...
Lactic acid bacteria are used in the food industry for a variety of reasons such as the production of cheese and yogurt products. Popular drinks such as kombucha are made using lactic acid bacteria, with kombucha having been known to have traces of Lactobacillus and Pediococcus once the drink is made. [23]
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).
Lacticaseibacillus paracasei (commonly abbreviated as Lc. paracasei) is a gram-positive, homofermentative species of lactic acid bacteria that are commonly used in dairy product fermentation and as probiotic cultures. Lc. paracasei is a bacterium that operates by commensalism.
In addition to lactic acid bacteria, yeasts also have been reported to have a biopreservation effect due to their antagonistic activities relying on the competition for nutrients, production and tolerance of high concentrations of ethanol, as well as the synthesis of a large class of antimicrobial compounds exhibiting large spectrum of activity against food spoilage microorganisms, but also ...
Due to more than a century of safe use, the FDA has granted L. bulgaricus a "grandfather" status, with an automatic GRAS status (generally recognized as safe). [17] Moreover, the Code of Federal Regulations mandates that in the US, for a product to be called yogurt, it must contain two specific strains of lactic acid bacteria: Lactobacillus bulgaricus and Streptococcus thermophilus, as ...
As lactic acid bacteria, the strains are Gram-positive, slender, rod-shaped, nonsporulating, and non-motile. [5] They are also obligately heterofermentative, meaning that they can convert hexose sugars into not just lactic acid, but also ethanol, CO 2, and/or acetic acid. [6]
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.
