Lactobacillus fermentum: Could EPS production ability be responsible for functional properties?

Area of Science:

• Microbiology
• Food Science
• Biotechnology

Background:

• Exopolysaccharides (EPS) are produced by many lactic acid bacteria (LAB), influencing dairy product properties like viscosity and texture.
• While LAB EPS are utilized in food manufacturing, the functional properties of EPS themselves, particularly from Lactobacillus species, are less understood.
• Lactobacillus fermentum is a species with known functional properties, but the connection to its EPS synthesis requires further investigation.

Purpose of the Study:

• To review the functional properties of Lactobacillus fermentum strains.
• To emphasize strains of Lactobacillus fermentum that produce exopolysaccharides (EPS).
• To investigate the potential relationship between EPS production and the functional/probiotic roles of Lactobacillus fermentum.

Main Methods:

• Literature review of recent scientific publications.
• Focus on studies reporting functional properties of Lactobacillus fermentum.
• Analysis of studies specifically addressing EPS production in Lactobacillus fermentum.

Main Results:

• Exopolysaccharide (EPS) production is a common trait in Lactobacillus fermentum.
• EPS-producing Lactobacillus fermentum strains often exhibit beneficial functional properties.
• A potential link exists between EPS synthesis and the probiotic capabilities of Lactobacillus fermentum.

Conclusions:

• Exopolysaccharide (EPS) production in Lactobacillus fermentum may contribute to its functional and probiotic characteristics.
• Further research is needed to fully elucidate the role of EPS in the bioactivity of Lactobacillus fermentum.
• Understanding this link can optimize the use of Lactobacillus fermentum in functional foods and probiotics.
