What is the scientific name of Lactobacillus?

Lactobacillus is a genus of lactic acid bacteria. They get their name from the fact that they ferment sugar into lactic acid. Lactic acid is a natural product of biological functioning.

Does Lactobacillus bacteria contain dairy?

Lactobacillus bacteria do not “contain dairy.” In many cases, dairy is used in their production. However, lactobacillus bacteria can feed on many kinds of sugar, whether taken from plants or from milk. Often, if dairy was used in the culturing process, that will be specified on the product label.

Is Lactobacillus Gram positive or negative?

Lactobacillus is a genus of Gram-positive, aerotolerant anaerobes or microaerophilic, rod-shaped, non- spore -forming bacteria. They are a major part of the lactic acid bacteria group (i.e., they convert sugars to lactic acid).

What is the microbiota of Lactobacillus?

Lactobacillus species constitute a significant component of the human and animal microbiota at a number of body sites, such as the digestive system, and the female genital system. In women of European ancestry, Lactobacillus species are normally a major part of the vaginal microbiota.

How many species are there in the genus Lactobacillus?

The genus Lactobacillus currently contains 44 species which are adapted to vertebrate hosts or to insects. In recent years, other members of the genus Lactobacillus (formerly known as the Leuconostoc branch of Lactobacillus) have been reclassified into the genera Atopobium, Carnobacterium, Weissella, Oenococcus, and Leuconostoc. The Pediococcus species P. dextrinicus has been reclassified as a Lapidilactobacillus dextrinicus and most lactobacilli were assigned to Paralactobacillus or one of the 23 novel genera of the Lactobacillaceae. Two websites inform on the assignment of species to the novel genera or species ( http://www.lactobacillus.uantwerpen.be/; http://www.lactobacillus.ualberta.ca/ ).

What is the role of lactobacillus in fermentation?

Lactobacilli comprise most food fermenting lactic acid bacteria and are used as starter cultures in industry for controlled fermentation in the production of wine, yogurt, cheese, sauerkraut, pickles, beer, cider, kimchi, cocoa, kefir, and other fermented foods, as well as animal feeds and the bokashi soil amendment. Lactobacillus species are dominant in yogurt, cheese, and sourdough fermentations. The antibacterial and antifungal activity of lactobacilli relies on production of bacteriocins and low molecular weight compounds that inhibits these microorganisms.

How many genes are in the lactobacillus genome?

Accordingly, the number of protein-coding genes ranges from 1,267 to about 4,758 genes (in Fructilactobacillus sanfranciscensis and Lentilactobacillus parakefiri, respectively). Even within a single species there can be substantial variation. For instance, strains of L. crispatus have genome sizes ranging from 1.83 to 2.7 Mb, or 1,839 to 2,688 open reading frames. Lactobacillus contains a wealth of compound microsatellites in the coding region of the genome, which are imperfect and have variant motifs. Many lactobacilli also contain multiple plasmids. A recent study has revealed that plasmids encode the genes which are required for adaptation of lactobacilli to the given environment.

How many species are there in lactobacillus?

To date (July 2010), it contains 168 species, some of which are used in the manufacture of fermented dairy, sourdough, meat, vegetable foods, or used as probiotics. The genus Lactobacillus belongs to the phylum Firmicutes, class Bacilli, order II Lactobacillales, and family Lactobacillaceae.

What are the different types of lactobacilli?

Based on the 16S rRNA sequences, lactobacilli are phylogenetically distributed in seven groups: Lb. buchneri (bu), Lb. casei (ca), Lb. delbrueckii (de), Lb. plantarum (pl), Lb. reuteri (re), Lb. sakei (sa), and Lb. salivarius (sl). Traditionally, the genus is split into three groups based on the carbohydrate fermentation pathways: (1) obligate homofermentative, (2) facultative heterofermentative, and (3) obligate heterofermentative lactobacilli. The two most obvious beneficial roles of lactobacilli are as starter cultures (to produce acid rapidly) and as probiotic cultures. Lactobacilli are one of the few contaminant bacteria that are able to grow in cheese after manufacture (as nonstarter lactic acid bacteria (NSLAB)). Lactobacilli as starters and as NSLAB may play different roles in the metabolism of lactose, lactate, and citrate, and in proteolysis and lipolysis, which are considered the primary events during cheese ripening.

What bacteria are used in cheese making?

Various lactobacilli are used in cheesemaking. As lactose is the only fermentable carbohydrate, low water activity and oxygen tension limit the growth of several species. However, some microorganisms are still able to grow under these environmental conditions and to influence maturation. Lactobacilli used in cheesemaking are either mesophilic or thermophilic. Several species of lactobacilli used in dairy fermentations as starters, flavor adjuncts, probiotics, or adventitious nonstarter lactic acid bacteria (NSLAB) are covered in other articles. These include the Lb. casei group, the Lb. delbrueckii group, Lb. helveticus, Lb. acidophilus, and Lb. plantarum. In addition, other species of lactobacilli are commonly used in fermentations. These include facultatively and obligately heterofermentative species such as Lb. brevis, Lactobacillus fermentum, Lb. buchneri, Lactobacillus kefiri, Lactobacillus rhamnosus, Lactobacillus curvatus, Lb. reuteri, Lb. coryneformis, Lb. hilgardii, and Lb. sakei. Most of these speices of Lactobacilli are not as well characterized as the other dairy lactobacilli. The above species are not important as starters for acidification but are mainly used in some dairy products for flavor, probiotic, antimicrobial, or textural attributes. Nonstarter lactobacilli originate from either the milk or the cheese manufacturing environment. Compared to the modern production of fermented milks, cheesemaking is less aseptic and thus may resemble the original production conditions. The effect of nonstarter lactobacilli on cheese quality can be positive, negative, or neutral depending on the strains that predominate and on the role of these strains during ripening. Several of the above species were studied because of their negative impact on flavor and texture of cheese when present as adventitious NSLAB. This article mainly focuses on the following species: Lb. brevis, Lb. buchneri, Lb. fermentum, Lb. reuteri, Lb. kefiri, Lb. rhamnosus, and Lb. curvatus.

What are lactobacilli used for?

They are mainly used in the manufacture of fermented dairy, sourdough, meat and vegetable foods or used as probiotics. The general utility of the Lactobacillus species is related to their GRAS (Generally Recognized as Safe) status and it will be dependent on the availability of cost-effective methods for production and delivery of viable cultures. In dairy products such as fermented milks and cheeses, the lactobacilli have multiple effects depending on the species, strain, manufacturing conditions and product. The two most obvious beneficial roles of lactobacilli are as starter cultures (to produce acid rapidly) and as probiotic cultures. However, they may also synthesize bacteriocins and exopolysaccharides, and contribute to flavor of different dairy products. In some circumstances, lactobacilli may also cause flavor and texture defects.

What is the taxonomic reclassification of lactobacillus?

What is lactobacillus acidophilus?
