Self-Nourishing and Armored Probiotics via Egg-Inspired Encapsulation

Area of Science:

• Microbiology
• Biotechnology
• Gastroenterology

Background:

• Gut microbiota is crucial for physiological functions, and its dysregulation is linked to diseases like obesity, diabetes, and IBD.
• Oral probiotic delivery faces challenges due to poor stability in the gastrointestinal environment.
• Effective delivery systems are needed to maintain gut microbiome health.

Purpose of the Study:

• To develop an innovative, egg-inspired encapsulation strategy for effective oral probiotic delivery.
• To evaluate the stability, functionality, and bioavailability of probiotics encapsulated using the PIE technology.
• To assess the potential of PIE as a practical platform for maintaining gut health.

Main Methods:

• Developed Probiotics-In-Egg (PIE) technology using phosvitin and ovalbumin for probiotic encapsulation.
• Tested PIE stability and functionality in a simulated gastrointestinal tract.
• Assessed PIE bioavailability and gut colonization in mouse models following oral administration.

Main Results:

• PIE demonstrated significantly enhanced probiotic survival and proliferation in simulated GI conditions.
• PIE effectively neutralized reactive oxygen species (ROS) and sustained probiotics in nutrient-depleted environments.
• Oral administration of PIE in mice showed excellent bioavailability and improved gut colonization.

Conclusions:

• The egg-inspired PIE technology offers a robust and effective method for oral probiotic delivery.
• PIE enhances probiotic stability and efficacy, addressing limitations of current delivery systems.
• This technology holds significant potential for maintaining a healthy gut microbiome and preventing associated disorders.
