Oligosaccharide Metabolism and Lipoteichoic Acid Production in Lactobacillus gasseri and Lactobacillus paragasseri

Abstract: Lactobacillus gasseri and Lactobacillus paragasseri are human commensal lactobacilli that are candidates for probiotic application. Knowledge of their oligosaccharide metabolic properties is valuable for synbiotic application. The present study characterized oligosaccharide metabolic systems and their impact on lipoteichoic acid (LTA) production in the two organisms, i.e., L. gasseri JCM 1131T and L. paragasseri JCM 11657. The two strains grew well in medium with glucose but poorly in medium with raffinose, an… Show more

“…Similar results were obtained in the antimicrobial activity tests ( Table 1 ), where five bacterial strains were selected. Several strains of gram-positive bacteria were mainly selected, as they are generally more sensitive to propolis than gram-negative bacteria [ 13 , 42 , 43 ], and because they are considered to be probiotics [ 44 , 45 ]. Meanwhile, E. coli was also chosen to include a representative of gram-negative bacteria.…”

“…In addition to providing energy to the host ( Huang et al., 2015 ), Ruminococcaceae are known to have beneficial effects on intestinal barrier function ( Leclercq et al., 2014 ). Further, Lactobacillus-gasseri , a symbiotic lactic acid bacterium, can inhibit the NF-κB signaling pathway and increase intestinal barrier integrity ( Shiraishi et al., 2021 ). Lactobacillus-gasseri can also regulate gut bacterial dysbiosis, alleviate colonic inflammation, and improve cognitive dysfunction in mice ( Yun et al., 2020 ).…”

“…49 Nevertheless, the identification of L. paragasseri is still lacking. With recent research supporting its probiotic functionalities, 50,51 our study provides a new L. paragasseri strain for this field, which has also been examined for potential probiotic use. However, L. paragasseri is not yet considered an edible probiotic because it has been discovered recently.…”
