The microbiota present in the processed olives and in the brine includes members of Enterobacteriaceae, Clostridium, Pseudomonas, Staphylococcus, LAB, yeasts, and sometimes mold. Figure 7. The global burden of IBD: from 2015 to 2025. (2008) have demonstrated that an alkaline treatment with a low NaOH strength and insufficient alkali penetration allowed for the presence of EDA and HyEDA in brines (Figure 109.5), and they inhibited the growth of L. pentosus. Lactobacillus pentosus modulates immune response by inducing IL-10 producing Tr1 cells. With respect to the viable LAB count, the results obtained showed a curve similar to the typical bacterial growth curve (Fig. Strittmatter CF. In fact, both EDA and HyEDA can explain most of the antimicrobial activity found in olive brines.

Pereira, T.C. In the stationary phase, a straight line was not observed (which would respect the ideality of a typical bacterial growth curve). Lactobacillus pentosus ABHEAU-05 survival during 21 days of refrigerated storage (4°C). An approach to the classification of lactobacilli using computer-aided numerical analysis.
The ability to adhere to the epithelial surface, the antagonistic activity against pathogenic microorganisms and the potential to colonize the intestine temporarily are also tested through in vitro tests17,22,9. 31772642 and 31672457), Ministry of Agricultural of the People’s China (2015-Z64 and 2016-X47), Hunan Provincial Science and Technology Department (2019TP2004, 2017NK2322, 2016WK2008, and 2016TP2005), Double First-Class Construction Project of Hunan Agricultural University (SYL201802003), and China Postdoctoral Science Foundation (2018M632963 and 2019T120705). (2019). Microbiol. Effect of inulin as prebiotic and symbiotic interactions between probiotics to improve fermented milk firmness. Transl.

If the species was not widely studied, the American Type Culture Collection (ATCC) was used to … Screening potential probiotic characteristics of.
The most abundant genera were Akkermansia, Bacteroides, Lactobacillus, and Parasutterella.
However, another study showed that providing five strains of Lactobacillus, also isolated from the equine intestine, did decrease the incidence of foal diarrhea (Yuyama et al 2004). Copyright © 2019. Moreover, the Shannon and Simpson index values were higher in the DSS-L. pentosus group than the DSS group (Figures 6C,D, p < 0.05).
However, there has been little research on the use of Lactobacillus pentosus to treat IBD induced by DSS. Appl Microbiol Biotechnol, 100 (2016), pp. All Rights Reserved. Proc. Similar to isolated strains AB-2 and AB-3, isolated strains AB-4 and AB-5 only developed on MRS agar (Fig. In this respect engineered strains of Lactobacillus plantarum and Lactococcus lactis have been shown to efficiently produce 2,3-BDO from inexpensive substrates such as whey permeate.

These metabolites were mainly composed of lipids and lipid-like molecules (48.87%), organoheterocyclic compounds (14.29%), and organic acids and their derivatives (12.03%, Figure 4). In contrast, isolated strain AB-3 grew during all the fermentation process from the first 4h showing minimal and constant concentration compared to isolated strains AB-1 and AB-2.

Copyright © 2020 Ma, Hu, Yan, Jiang and Liu. were determined, the average was taken. As a result, the olives from Geracese cultivar showed wide LAB population in fermented samples, in this case, olives were inoculated with Lactobacillus plantarum and L. casei and maintained for 180 days at the room temperature. Our data indicate that L. pentosus improves intestinal barrier function by remodeling the intestinal microbial structure and increasing the abundance of Akkermansia. R.P. (2018).
Phylogenetic tree showing the interrelationship of Lactobacillus pentosus ABHEAU-05 with closely related species of Lactobacillus and other related genera. The survival of L. pentosus ABHEAU-05 in refrigerated fermented milk was verified through plating on MRS medium by the microdrop technique. Inflammatory bowel disease (IBD) is a chronic disease caused by the interaction of environmental, immune, genetic, and other factors (Batura and Muise, 2018). LDA was then used to estimate the magnitude of the effect of species abundance on the effect of differences between each group. Lactic acid bacteria are recognized to play an important role in olive fermentation and Lactobacillus plantarum and Lactobacillus pentosus are, in fact, regarded as the main species leading this process, being often used as starters in guided olive fermentation. Lactobacillus casei Shirota was used as the reference strain.
Bacteriol. Subsequently, the counting of each plate was carried out. Additionally, the antimicrobial activity of oleuropein, hydroxytyrosol, and HyEDA against several microorganisms found in table olives was studied (Table 109.3). 2B) while isolated strain AB-3 showed rhizoid acuminate white colonies, with dry consistency (Fig. The amino acid requirements of twenty-three lactic acid bacteria. S.L. Most commonly, inflammation induces neutrophil aggregation and promotes the formation of neutrophil extracellular traps, and furanoid fatty acids induce NADPH oxidase and the production of reactive oxygen species in the mitochondria (Khan et al., 2018). All rights reserved. Exosomes mediate LTB4 release during neutrophil chemotaxis. Gut 65, 330–339. Those LAB have demonstrated their ability to survive to acidic conditions. Pineapple tepache, a traditional Mexican fermented beverage, was used for the isolation of lactic acid bacteria with probiotic potential, one of which withstood the in vitro tests. As discussed before, LAB are the most important group of fermentative bacteria in the table olives production, they are divided in homofermentative bacteria (Lactobacillus, Streptococcus, and Pediococcus) and heterofermentative bacteria (Leuconostoc and some members of Lactobacillus) where the most important role is exerted by Lactobacillus spp.
