Summary
Yeasts offer unique probiotic and postbiotic benefits distinct from bacteria. This review introduces the yeast-biotic continuum, highlighting their bioactive components and diverse health applications.
Area of Science:
- Microbiology
- Immunology
- Biotechnology
Background:
- Research on probiotics and postbiotics traditionally focuses on bacteria, underrepresenting yeasts.
- Yeasts possess unique eukaryotic cellular structures and secretory pathways, offering distinct functional properties.
Purpose of the Study:
- To review the relationship between yeast probiotics and yeast-derived postbiotics.
- To propose the concept of a "yeast-biotic continuum".
- To explore the distinct functional properties of yeasts in the context of biotics.
Main Methods:
- Literature review of yeast probiotics and postbiotics.
- Conceptual framework development for the yeast-biotic continuum.
- Analysis of yeast-derived bioactive components and their functions.
Main Results:
- Yeasts exhibit unique functional properties due to their eukaryotic nature and bioactive components like β-glucans and mannoproteins.
- The yeast-biotic continuum model describes functionality from live cells to inactivated preparations.
- Yeast-derived biotics play roles in immune modulation, barrier support, and host-microbiota interactions.
Conclusions:
- Yeasts represent a significant, underutilized resource in the field of probiotics and postbiotics.
- The yeast-biotic continuum provides a novel framework for understanding yeast functionality.
- Further research and technological advancements can unlock the full potential of yeast-derived biotics.

01:22Bioreactor Controls-III
Strain improvement is a foundational strategy in industrial microbiology aimed at maximizing microbial productivity, particularly because natural isolates typically yield commercially valuable products in very low concentrations. Although optimizing the culture medium and environmental conditions can improve yields, these adjustments are inherently limited by the organism’s genetic potential. As a result, the focus shifts toward genetic modifications to enhance biosynthetic capacity. The...
01:28Yeast Signaling
Yeasts are single-celled organisms, but unlike bacteria, they are eukaryotes (cells with a nucleus). Cell signaling in yeast is similar to signaling in other eukaryotic cells. A ligand, such as a protein or a small molecule released from a yeast cell, attaches to a receptor on the cell surface. The binding stimulates second-messenger kinases to activate or inactivate transcription factors that further regulate gene expression. Many of the yeast intracellular signaling cascades have similar...
01:22Probiotics
Probiotics are live, non-pathogenic microorganisms that confer health benefits by modulating the gut microbiota. The human gastrointestinal tract harbors a complex microbial ecosystem, and the balance of this microbiota is crucial for digestive and systemic health. Among the most extensively studied and utilized probiotics are species formerly classified within the genera Lactobacillus and Bifidobacterium. These organisms not only naturally colonize the human gut but are also consumed through...
01:21Microbiota Modulation by Antibiotics
Antibiotics have revolutionized modern medicine by saving countless lives from bacterial infections. However, their widespread use has inadvertently harmed the delicate balance of the human gut microbiota. The gut microbiota, a complex community of bacteria, archaea, viruses, and fungi, plays a vital role in regulating metabolism, immune responses, and maintaining intestinal health. Antibiotics, especially broad-spectrum types, disrupt this ecosystem by eradicating both harmful and beneficial...
01:27Microbes in the Production of Fermented Foods
Lactic acid bacteria (LAB) and molds are instrumental in fermenting plant-based foods to enhance preservation and ensure year-round availability. These microbial processes convert plant carbohydrates into organic acids and other metabolites that inhibit spoilage organisms and contribute to the sensory qualities of the final product.In sauerkraut production, cabbage goes through a microbial succession that starts with cocci such as Leuconostoc mesenteroides. These microbes begin fermentation by...
01:29Microbes in Food Production
Microbial fermentation is central to food biotechnology, enhancing flavor, texture, preservation, and stability. Fermentative microorganisms metabolize carbohydrates into organic acids, alcohols, and other metabolites that inhibit spoilage organisms and improve digestibility while contributing distinctive sensory qualities.In baking, amylases naturally present in flour hydrolyze starch into monosaccharides such as glucose, which Saccharomyces cerevisiae ferments anaerobically.
