“…These advantageous effects are antitumor, anti-ulcer, antioxidant activities, cholesterollowering activity, and immune-stimulating activities [4]. Although some EPSs form a biofilm that causes hygiene problems, other EPSs derived from LAB play crucial role in improving the rheology, texture, mouth feel of fermented food formulations in food industry [1,5]. Bioflocculants, bio-absorbents, heavy metal removal agents, drug delivery agents, and others are the new application of EPSs [6].…”

Exopolysaccharides (EPSs) are high molecular weight and biodegradable polymers. They are biosynthesized by a wide range of bacteria. Lactic acid bacteria (LAB) are also able to produce EPSs. EPSs can be classified into two groups. These are homopolysaccharides and heteropolysaccharides. Homopolysaccharides are polymers which are composed of one type of monosaccharide. Heteropolysaccharides are polymers of repeating units. They are composed of two or more types of monosaccharides. Producer microorganisms don't use the bacterial EPSs as energy sources. EPSs have been used in the production of several fermented foods such as thickeners, stabilizers, emulsifiers and gelling or water-binding agents. In addition, EPSs have some positive effects on health. These are to have antitumor effects, immune-stimulatory activity and to lower blood cholesterol. Incubation temperature and time, growth medium, acidity of growth medium and type of strain have an impact on EPSs production.In this review, EPSs production by LAB, including chemical composition, structure, biosynthesis, genetics and application of EPSs produced by LAB is discussed.

“…Similar to polysaccharides isolated from plant, fungal, and marine sources, exopolysaccharides (EPS) from several probiotics also exhibit desirable antioxidative effects. Different microbial sources of EPS, including Enterococcus faecium , L. plantarum RJF4, L. plantarum , and Weissella cibaria GA44, can scavenge free radicals (Abdhul et al, ; Adesulu‐Dahunsi, Sanni, & Jeyaram, ; Dilna et al, ; Mahdhi et al, ). This special biological function mainly depends on monosaccharide composition, molecular weight, and branching structures (Dilna et al, ).…”

In recent years, probiotics have received increasing attention and become one type of popular functional food because of their many biological functions. Among these desirable biological functions, the immune regulation, antioxidative activities, and antimicrobial effects are essential properties to maintain host health. Probiotics can regulate the immune system and improve the antioxidative system by producing microbial components and metabolites. Meanwhile, probiotics also possess antimicrobial abilities owing to their competition for nutrient requirements and mucus adherence, reducing pathogenic toxins, producing antimicrobial metabolites (short‐chain fatty acids, bacteriocins, reuterin, linoleic acid, and secondary bile acids) and enhancing intestinal, or systemic immunity. Therefore, probiotics could be used to alleviate heavy metal toxicity and metabolic disorders by improving immunity, the antioxidative system, and intestinal micro‐environment. This comprehensive review mainly highlights the potential health promoting activities of probiotics based on their antioxidative, antimicrobial, and immune regulatory effects. Practical applications The antioxidative defense and the immune system are essential to maintain human health. However, many factors may result in microbial dysbiosis in the gut, which subsequently leads to pathogenic expansion, oxidative stress, and inflammatory responses. Therefore, it is important to explore beneficial foods to prevent or suppress these abnormal responses. Successful application of probiotics in the functional foods has attracted increasing attention due to their immune regulatory, antioxidative, and antimicrobial properties. The aim of this review is to introduce immune regulatory antioxidative and antimicrobial effects of probiotics, which provides some basic theories for scientific research and development of potential functional foods.

“…Several works focus on the EPS production by Lactobacillus (Ismail and Nampoothiri, 2010;Dilna et al, 2015;Fontana et al, 2015;Salazar et al, 2015;Oleksy and Klewicka, 2016 The genes encoding for proteins responsible for EPS synthesis by mesophilic lactic bacteria are generally located on a plasmid. In Lactococcus, the production of EPS is less stable, the main reasons being the plasmidic location of the production genes and the presence of a mobile insertion sequence (IS, e.g.…”

Twenty-eight strains of lactic bacteria were isolated from fermented wheat "hamoum" and phenotypically attributed to the following species: seven strains of Lactococcus lactis subsp. lactis, six strains of Lactobacillus brevis and 15 strains of Lactobacillus plantarum. The acidifying behavior of the strains is considerably variably demanding on considered strain. The amounts of lactic acid produced reached 9.7 g for lactococci. Strains (27) showed proteolytic activity in the presence of 1% skimmed milk. The lipolysis activity of L. lactis strains was greater than that expressed by lactobacilli. The search for aromatic activity showed that four out of ten citratase producing strains can produce acetoin. The results indicate that L. plantarum is the most dominant strain in the "hamoum" with the most important technological characteristics.
