lactobacillus jensenii infection

Examples of micro-organisms used for the production of bioactive peptides. (1995a,b) identified two ACE inhibitory peptides, Val-Pro-Pro and Ile-Pro-Pro, derived from milk by fermentation with a combination of L. helveticus CP790 and Saccharomyces cerevisiae.

The residual cells were more than 50% of the initial cells even after 2 h of incubation at pH 2 or 3. Whereas all bacteria could tolerate 0.3%-1% bile salt, L. plantarum LP3 was the most resistant strain of all. Lactobacillus casei and Lactobacillus paracasei strains isolated from Kurdish cheese displayed considerably higher survival at 120 min of exposure at pH 2.0 than their corresponding strains of origin (Tofangsazan, 2014). The BG-1 strain had the highest volatile acidity, which is a parameter associated with a sensorial defect in distilled beverages. Table 3.1. rhamnosus GG.

Cheeses made with the addition of Lactobacillus casei 279, L. casei LAFTI® L26 or L. acidophilus LAFTI® L10 had significantly higher ACE inhibitory activity than those without any probiotic adjunct.

Togwa, a lactic acid–fermented maize and sorghum gruel, inhibits the growth of some enterotoxin-producing bacteria in children <5 years of age. Several cases of sepsis have been reported in humans administered with L. rhamnosus [26,40–42], Lactobacillus casei var. In the majority of healthy reproductive age women, the VMB is dominated by lactobacilli; although these bacterial communities can vary considerably between individuals and over time. The first study of human vaginal microbiota was published by Döderlein in 1892.

Colonisation of the intestinal mucosa with strains of Lb. It is also found on the skins of grapes at the time of their harvest. The gut microbiota is also known to engage in similar relationships with host endothelium to help maintain homeostasis necessary for organ functioning.

Lactobacillus plantarum indigenous to a variety of cereal-based fermented foods is also associated with the gastrointestinal tract of humans (Ahrné et al., 1998; Molin, 2001). In this pattern, a series of potentially bioactive peptides could be detected. However, in the wine production, differently from the cachaça process, there is no distillation step where many chemical compounds could be lost thus prejudicing the fermentation traceability. [4][5][6] L. jensenii is sometimes used in producing fermented foods. The vaginal vault is colonized within 24 h of a female child’s birth and remains colonized until death.

only when there is a clear pairwise interaction or when mutual reciprocity has been directly investigated and demonstrated. To increase the number of beneficial bacteria in the gut, large numbers of probiotic bacteria have to be consumed by means of capsules or by using food as vector. Strain ST712BZ revealed only 38% hydrophobicity, but 63% of the cells adhered to HT-29 cells, compared to 32% adherence recorded for Lb.

Glycogen, which is a storage form of glucose, has been shown to promote growth of lactobacilli (Mirmonsef et al., 2016). This suggests that togwa may possess probiotic properties (Kingamkono, Sjögren, & Svanberg, 1998). On the other hand, ingestion of probiotic strains with food or dairy products raises the pH in the stomach to 3.0 or higher (Iñiguez-Palomares et al., 2007). (2012) stated L. plantarum and L. casei strains isolated from Koozeh cheese were resistant to 0.3% of bile salt.

It was recently described a correlation between the chemical profile of cachaças and the use of different commercial and autochthonous S. cerevisiae yeast strains.
(2001) found a great variety of yeasts strains such as S. cerevisiae, Kluyveromyces marxianus, Pichia heimii, Pichia subpelliculosa, ebaryomyces hansenii, and Hanseniaspora uvarum microorganism in the must during the alcohol fermentation processes.

In this procedure, rice bran, corn flour, or soybean, are mixed with the sugarcane juice, as nutritional supplements to support the reproduction of the natural S. cerevisiae. These results contributed with the discrimination of S. cerevisiae strains used during the fermentation of cachaças distilled in columns. strain CS93 isolated from pozol were identified and exhibited activities against several Gram-positive and Gram-negative bacteria, yeasts and moulds (Phister et al., 2004). The highest concentrations of acetic and lactic acids are probable due to bacterial contamination during the natural S. cerevisiae proliferation. rhamnosus GG. As one of these human-microbe habitats, the female genital tract is colonized by bacterial communities that are known to confer antimicrobial protection to the vagina and play a crucial role in health [2,3].

Barley and oats contain β-glucan (Angelov et al., 2006), a prebiotic that may contribute to the reduction of LDL-cholesterol levels by 20–30%, and in this way may also contribute to a decrease in the risk of cardiovascular diseases (Gallaher, 2000; Stark & Madar, 1994; Wrick, 1994).

mundtii ST4V. MICs of vancomycin were high (>256 microg/mL) for all other species except Lactobacillus gasseri and Lactobacillus jensenii. The vaginal microbiota can also be altered by external factors, such as environmental exposures, microbial interspecies competition or commensalism, and hygiene behaviors [4].

Oligopeptides that cannot be transported into the cells can be further degraded after lysis of the bacterial cell, which allows the release of intracellular peptidases, such as di-, tri-, amino- or endopeptidases (Lopez-Fandino et al., 2006).

plantarum isolated from sourdough has also been reported (Johansson, Molin, Jeppsson, Nobaek, & Ahrné, 1993). Lactobacilli benefit the host by producing lactic acid, which acidifies the vaginal microenvironment and provides protection against genital infections. This relationship is similar to symbiotic relationships seen in plants, e.g. Hassanzadazar et al. In healthy women, the vaginal ecosystem is dominated by Lactobacillus species. However, factors as raw materials, pH, and temperature control should also be considered. Therefore, the vaginal microbiota suffers significant structural changes at various stages in a woman’s life that are closely associated to the level of estrogens in the body [4].

Lactobacillus plantarum and Lactobacillus casei, Lactobacillus ferintoshensis, Lactobacillus fermentum, Lactobacillus jensenii, Lactobacillus murinus, Lactococcus lactis, Enterococcus sp., and Weissella confusa were the species isolated. In these studies, L. plantarum and Lactobacillus jensenii were found to be more resistant to stomach conditions like low pH. mundtii ST4V had no negative effect on the sensory qualities of the final product.

lactis CRL 581. For this purpose, boza was prepared based on the traditional recipe (Todorov, 2010; Todorov et al., 2009). The protective effect of Lactobacillus-dominant VMB have also been attributed to hydrogen peroxide; however, production of this antimicrobial compound by lactobacilli in hypoxic conditions of the vagina remains controversial (O’Hanlon et al., 2013). (2002) detected immunostimulatory peptides in milk fermented with a L. helveticus strain. As such, we echo the suggestion by Mushegian and Ebert (2016) that the term ‘mutualism’ be used more sparingly, i.e. Vaginal mucosa is rich in nutrients such as glucose or amino acids, which allows for the colonization by bacteria that forms the vaginal microbiota.

Similarly, a study on the persistence of human-associated Bacteroidetes in the gut (discussed in Section 2.3) showed that some bacterial species can exclude an invader by producing bactericidal effectors triggered by direct physical contact, and that this activity is mediated by resistance evolution and relative population densities between species (Wexler et al., 2016).
The process of alcohol fermentation can be divided into two steps. Antimicrobial compounds produced by Bacillus sp.

Table 35.1. Identification of the yeast strains in the cachaça production has been carried out through yield, conversion, efficiency, and microbiological analyses of the fermentative process. They indicated that the development of antioxidant activity was strain-specific with Leuconostoc mesenteroides ssp. All these protective mechanisms have made that lactobacilli are proposed for the maintenance of the vaginal mucosa integrity and prevention of disorders related to alteration of vaginal microbiota, such as vaginitis and vaginosis.

L. jensenii was discovered by F. Gasser, M. Mandel, and M. Rogosa in 1969.

mundtii ST4V, to evaluate its survival in boza, and to study the antimicrobial activity of the strain in situ. The concentrations of acetic acid and DMS are about 10-fold higher in the cachaças from natural yeasts than in those produced with industrial yeasts. (2010) found that the presence of related bacteria in the resident microbiota can facilitate bacterial invasion.

A snack exhibiting the combined postulated beneficial effects of bran and probiotic bacteria may serve as an alternative to soy-based and milk-based yogurts (Salovaara, 1996; Salovaara & Simonson, 2003). L. jensenii is Gram-positive, rod-shaped, negative for catalase and oxidase, and anaerobic. All of these findings, along with future studies, will surely help in promoting the consumption of this interesting Mayan drink. (1999) found that the LAB present in various LAB-fermented foods, such as sourdough, is similar or, in some cases, identical to species found in the gastrointestinal tract of humans and animals.

Schawn et al.

Cereal grains have a high nutritive value and are distributed worldwide, making cereal a very suitable raw material for the development of various fermented functional foods (Angelov, Gotcheva, Kuncheva, & Hristozova, 2006).

Certain cell envelope-associated proteinases (CEP) of LAB can release bioactive health-beneficial peptides during milk fermentation. Randomized Controlled Trials of Mixed Probiotic Strains and Their Adverse Effects. Adhesion of strains ST194BZ, ST284BZ, ST414BZ, ST461BZ, ST462BZ and ST664BZ to HT-29 cells ranged from 18% to 22%, which is similar to that reported for Lb. It is also found on the skins of grapes at the time of their harvest. In normal acid tolerance assay, the viability of candidate probiotic bacteria is determined by exposing them to low pH in a buffer solution for a period of time, during which the number of surviving organisms remaining is determined (Hassanzadazar et al., 2012; Hashemi et al., 2014a). In a 4-year Finish study to assess the possibility of lactobacilli to cause serious infections, the researchers monitored the frequency of bacteremia due to Lactobacillus species in southern Finland. One case of Lactobacillus jensenii-associated empyema has been reported [43]. Bile was reported to be involved in growth delay of Lactobacillus strains isolated from traditional Iranian cheese after 2 h incubation in the presence of 0.3% bile salt (Jafari et al., 2011; Tajabadi Ebrahimi et al., 2011). The cell-wall bound proteinases, which have a very broad substrate specificity, initiate the proteolytic attack and release of oligopeptides.

The aim of the study of Todorov et al. In vitro study (Mirzaei et al., 2012) showed that L. plantarum strains isolated from Lighvan cheese were able to survive after 2 h of exposure at pH 1.55, where the number of final surviving bacteria ranges between 6.3 and 7.86 log cfu/g. More research into the human virome and its effects on invasions is greatly needed. Hashemi et al. (2007) investigated the production of antioxidant activity during fermentation of whey with 25 LAB strains. Various levels of auto- (self-) aggregation between the probiotic bacteria and co-aggregation with Li.

These two peptides, of casein origin, exert in vivo antihypertensive activity in spontaneously hypertensive rats (SHR) and in hypertensive subjects (Takano, 1998). Their study identified four different species of lactobacilli, Lactobacillus crispatus, L. gasseri, L. iners, and L. jensenii.
