“…The HePs from Lactobacillus gasseri was investigated for its antibacterial activity on various test pathogens which revealed that it has inhibited Listeria monocytogenes MTCC 657 to a greater extent [97]. EPS from Lactobacillus sp.Ca6 inhibited the growth of Micrococcus luteus and Salmonella enterica with zone of inhibition of around 14 and 10 mm, respectively [32]. EPS-C70 from camel milk exhibited 2 to 3 log reduction against tested food-borne pathogens with initial population of 9 log CFU/ml and highest inhibition was observed against Staphylococcusaureus and E. coli [31].…”

Exopolysaccharides (EPS) are extracellular macromolecules excreted as tightly bound capsule or loosely attached slime layer in microorganisms. They play most prominent role against desiccation, phagocytosis, cell recognition, phage attack, antibiotics or toxic compounds and osmotic stress. In the last few decades, natural polymers have gained much attention among scientific communities owing to their therapeutic potential. In particular the EPS retrieved from probiotic bacteria with varied carbohydrate compositions possess a plenty of beneficial properties. Different probiotic microbes have unique behavior in expressing their capability to display significant health promoting characteristics in the form of polysaccharides. In this new era of alternative medicines, these polysaccharides are considered as substitutes for synthetic drugs. The EPS finds applications in various fields like textiles, cosmetics, bioremediation, food and therapeutics. The present review is focused on sources, chemical composition, biosynthetic pathways of EPS and their biological potential. More attention has been given to the scientific investigations on antimicrobial, antitumor, anti-biofilm, antiviral, anti-inflammatory and immunomodulatory activities.

“…The EPS extracted from Lactobacillus sp. Ca6 had shown to possess in-vivo dermal wound healing property in male wistar rats [32]. The EPS of Lactobacillus strains have the ability to stimulate innate immune response and EPS from Lactobacillus plantarum JLK0142, Leuconostoc citreum, Lactobacillus johnsonii 142 and Bifidobacterium sp.…”

Oxidative stress tolerance and antioxidant capacity of lactic acid bacteria as probiotic: a systematic review

2020

View full text Add to dashboard Cite

Lactic acid bacteria (LAB) are the most frequently used probiotics in fermented foods and beverages and as food supplements for humans or animals, owing to their multiple beneficial features, which appear to be partially associated with their antioxidant properties. LAB can help improve food quality and flavor and prevent numerous disorders caused by oxidation in the host. In this review, we discuss the oxidative stress tolerance, the antioxidant capacity related herewith, and the underlying mechanisms and signaling pathways in probiotic LAB. In addition, we discuss appropriate methods used to evaluate the antioxidant capacity of probiotic LAB. The aim of the present review is to provide an overview of the current state of the research associated with the oxidative stress tolerance and antioxidant capacity of LAB.

“…However, DPPH radical scavenging ratio of IPL‐treated strain EPS was higher than Lactobacillus rhamnosus zy EPS noted at 57% (Ng et al ., 2016) and lactobacillus sp. Ca6 EPS noted at 53.62% (Trabelsi et al ., 2017) at the concentration of 5.0 mg mL −1 . The result shown that the EPS produced by IPL‐treated strain basically the same DPPH radical scavenging capacity.…”

Summary In this work, IPL technology was used for improving the production of exopolysaccharide (EPS) in Lactobacillus bulgaricus. The effects of fluence per pulse, pulse number and pulse distance were investigated. Through GC–MS, Fourier transform infrared (FT‐IR), 1H nuclear magnetic resonance (1H NMR), X‐ray diffraction (XRD) and scanning electron microscopy (SEM) study the influence on EPS primary chemical structure and surface morphology. The antioxidant activity of EPS was evaluated by DPPH, Fe2+ chelating and reducing power assays. The findings demonstrate that IPL could be a novel environment protection method for improving the production of EPS. The research results provide a theoretical basis for whether IPL is a new type of environmental protection method and can be used to improve EPS production.
