Abstract

The aim of the present work was to assess the probiotic potential of lactic acid bacteria (LAB) isolated from huauzontle (Chenopodium berlandieri spp. Nuttalliae) inflorescences; additionally, multifunctional bioactivities of the intracellular content and cell wall fractions of the selected strains were also determined. Eight strains identified as Lactiplantibacillus plantarum, one as Lactobacillus pentosus and one as Pediococcus pentosaceus, were pre-selected according to their survival rate to acid (range 78.67 to 97.11%) and bile salt (range 49.62 to 55.23%) exposure, and their potential probiotic properties were evaluated. Overall, all strains were able to survive to several technological conditions and production of exopolysaccharides and β-galactosidase activity, auto-aggregation (> 40%), hydrophobicity (31.27–53.56%), coaggregation (41–63%), and mucosa adhesion capacity (> 70%). Besides, no biogenic amine production, mucin degradation, and γ-hemolysis activity was observed. Strains with the best probiotic properties were selected and showed to be resistant to four different antibiotics, but conjugation frequency was not found for filter mating. A survival higher than 75% was registered after bacterial exposure to simulated gastrointestinal conditions. Furthermore, whole cells, intracellular contents, and cell wall fractions of these selected strains exhibited antioxidant and anti-inflammatory activities and promoted splenocyte cell proliferation. Our results indicated that epiphytic bacteria from huauzontle not only met basic criteria for probiotics, but also represent a source of bioactive metabolites with potential therapeutic or preventive activity against stress- and inflammatory-mediated disorders; however additional experiments are still required.
