“…Moreover, microbial levan can be a good source of pure fructose production. The bio-degradable film obtained with levan has a high potential to be used in different areas, especially in food packaging [ 279 ]. In the biomedical sectors, levan has many applications due to its biocompatibility and antibacterial [ 215 , 218 ], anticancer [ 215 , 216 , 217 ], antioxidant [ 218 ], anti-inflammatory, immunomodulatory [ 219 ], and prebiotic activities [ 220 ].…”

Bacterial exopolysaccharides (EPS) are essential natural biopolymers used in different areas including biomedicine, food, cosmetic, petroleum, and pharmaceuticals and also in environmental remediation. The interest in them is primarily due to their unique structure and properties such as biocompatibility, biodegradability, higher purity, hydrophilic nature, anti-inflammatory, antioxidant, anti-cancer, antibacterial, and immune-modulating and prebiotic activities. The present review summarizes the current research progress on bacterial EPSs including their properties, biological functions, and promising applications in the various fields of science, industry, medicine, and technology, as well as characteristics and the isolation sources of EPSs-producing bacterial strains. This review provides an overview of the latest advances in the study of such important industrial exopolysaccharides as xanthan, bacterial cellulose, and levan. Finally, current study limitations and future directions are discussed.

“…Levan from Paenibacillus polymyxa was used to obtain a biodegradable film, also consisting of bentonite and selected essential oils with antimicrobial properties. The film containing peppermint oil showed the highest antimicrobial activity against Candida albicans , film containing lemon oil was effective against S. aureus and one with citronella showed activity against E. coli [ 120 ]. This solution has the potential to be used in biodegradable food packaging.…”

Polysaccharides are essential components with diverse functions in living organisms and find widespread applications in various industries. They serve as food additives, stabilizers, thickeners, and fat substitutes in the food industry, while also contributing to dietary fiber for improved digestion and gut health. Plant-based polysaccharides are utilized in paper, textiles, wound dressings, biodegradable packaging, and tissue regeneration. Polysaccharides play a crucial role in medicine, pharmacy, and cosmetology, as well as in the production of biofuels and biomaterials. Among microbial biopolymers, microbial levan, a fructose polysaccharide, holds significant promise due to its high productivity and chemical diversity. Levan exhibits a wide range of properties, including film-forming ability, biodegradability, non-toxicity, self-aggregation, encapsulation, controlled release capacity, water retention, immunomodulatory and prebiotic activity, antimicrobial and anticancer activity, as well as high biocompatibility. These exceptional properties position levan as an attractive candidate for nature-based materials in food production, modern cosmetology, medicine, and pharmacy. Advancing the understanding of microbial polymers and reducing production costs is crucial to the future development of these fields. By further exploring the potential of microbial biopolymers, particularly levan, we can unlock new opportunities for sustainable materials and innovative applications that benefit various industries and contribute to advancements in healthcare, environmental conservation, and biotechnology.

“…Antimicrobial effects were evaluated against several microorganisms by the addition of calendula, citronella, lemon, tamanu, and peppermint oil. The greatest antimicrobial activity was obtained against Candida albicans with the levan/bentonite/peppermint oil film (Koşarsoy Ağçeli et al ., 2022).…”

SummaryExopolysaccharides (EPS) are high‐valued biopolymers produced by microorganisms, which are secreted to the outside of the microbial cell as capsules or soluble slime and have unique characteristics that make their application possible in multiple industries. EPS have shown antioxidant, prebiotic, and antimicrobial activity. In addition, they have been described as non‐toxic, biodegradable, and safe biopolymers for applications in food processes. Due to these characteristics, they became essential complements in the design of environmentally friendly packaging, mainly in the development of bioactive, edible, and intelligent films. In this sense, the objectives of this review were to discuss relevant issues on EPS production for environmentally sustainable food packaging, including principles, recently identified sources, and biosynthesis of different types of EPS produced by microorganisms on different substrates. The potential use of these components in manufacturing packaging films is also discussed as a promising strategy to extend the shelf life of foods.
