Summary
Dietary fibers like beta-glucans (BGs) modulate gut microbiota (GMB) for health benefits. This review explores BG
Area of Science:
- Microbiology and Nutrition Science
- Gut Health and Microbiome Research
Background:
- The human gut microbiota (GMB) is integral to health and disease.
- Diet significantly influences GMB composition and function.
- Dietary fibers, particularly beta-glucans (BGs), offer health benefits by modulating GMB.
Purpose of the Study:
- To review the metabolization of beta-glucans (BGs) by gut microbiota (GMB).
- To examine the effects of BGs on GMB population dynamics and gut infections.
- To assess the prebiotic potential, fermentation (in vitro and in vivo), and processing effects on BG fermentability.
Main Methods:
- Literature review synthesizing existing research on beta-glucans and gut microbiota.
- Analysis of studies focusing on GMB metabolization, population shifts, and fermentation.
- Inclusion of in vitro and in vivo fermentation data, alongside processing impact assessments.
Main Results:
- Beta-glucans (BGs) are metabolized by gut microbiota (GMB), influencing its composition.
- BGs demonstrate prebiotic effects, promoting beneficial microbial growth.
- Fermentation of BGs yields health-associated metabolites; processing affects their fermentability.
Conclusions:
- Beta-glucans (BGs) positively modulate gut microbiota (GMB), offering therapeutic potential for gut health.
- Understanding BG-GMB interactions is crucial for developing functional foods.
- Further research into processing effects can optimize BG's bioactive properties.

02:11The Roles of Bacteria and Fungi in Plant Nutrition
36.5K
Plants have the impressive ability to create their own food through photosynthesis. However, plants often require assistance from organisms in the soil to acquire the nutrients they need to function correctly. Both bacteria and fungi have evolved symbiotic relationships with plants that help the species to thrive in a wide variety of environments.

The gut microbiome is formed by a vast and diverse community of bacteria that colonizes our large intestine. These bacteria start residing in the gut from birth and continue diversifying throughout life, influenced by factors such as diet, lifestyle, and stress. The gut bacterial community also includes bacteria from food and those that enter the colon through the anus.
The normal gut flora of the colon plays a critical role in generating essential vitamins such as vitamins K, B5, and B7.

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.
