Feed Postbiotics-Extracellular Polysaccharides
Extracellular polysaccharides (EPS), also known as exopolysaccharides, exhibit structural and functional diversity reflecting the microorganisms from which they originate. They are found in various forms such as cell-bound capsular polysaccharides, unbound "slime", and as part of the O-antigen component of lipopolysaccharide, showcasing a broad array of biological functions. BioVenic offers tailored solutions for utilizing extracellular polysaccharides as postbiotics in animal feed. Our comprehensive suite of services includes analytical solutions for EPS, safety and efficacy assessments, mechanism studies, and production optimization.

Biological Functions of EPS
EPS derived from diverse sources are shaped by factors like monosaccharide composition, glycosidic linkage, and chemical modifications, which determine aspects such as conformation, chain expansion, and molecular weight. These constituents collectively contribute to the health-promoting attributes of EPS. Probiotic bacteria-produced EPS are particularly noteworthy for their therapeutic value, encompassing antimicrobial, immunomodulatory, anti-inflammatory, antioxidant, anti-tumor, anti-viral, anti-diabetic, anti-ulcer, and cholesterol-lowering activities.
Extracellular Polysaccharides Structural Analysis
The structural details of extracellular polysaccharides are elucidated through examination of monosaccharide composition, anomeric configurations, glycosidic linkages, the presence of repetitive units, noncarbohydrate substituents, and the depiction of a chemical molecular structure or a composite model. Various techniques such as hydrolysis for chemical degradation, SEC-chromatography and HPLC/HPAEC for separation, and NMR spectroscopy for identification aid in the analysis of microbial extracellular polysaccharides. This information is crucial for developing extracellular polysaccharides for application in animal feed postbiotics.
Safety and Efficacy Assessment of Extracellular Polysaccharides
Our platform for feed safety analysis is proficient in identifying detrimental components, such as toxins, within extracellular polysaccharides products that may pose risks to animals. Furthermore, we offer a diverse array of animal in vivo and in vitro models to assess the safety and efficacy of exopolysaccharides in specific animal contexts. Key research areas encompass evaluating the impact of extracellular polysaccharides on growth patterns, intestinal well-being, immune responses, and antioxidant capabilities.
Exploration of Mechanisms Involving Extracellular Polysaccharides
The varied landscape of polysaccharide structures, properties, and functions underscores the critical role of this matrix component in enabling bacteria to thrive across diverse environments. Through our specialized microbial extracellular polysaccharide research infrastructure, we delve into the structural attributes of microbial extracellular polysaccharides and their effects in both in vitro and in vivo settings. This facilitates a thorough investigation into the mechanisms underpinning the actions of microbial extracellular polysaccharides.
