Current Issues in Intestinal Microbiology
|August 1, 2006
Summary
Probiotic strains, including Lactobacillus and Bifidobacterium, offer health benefits by combating pathogens and modulating the immune system. Their effectiveness relies on survival and colonization within the human gastrointestinal tract.
Area of Science:
- Microbiology
- Gastroenterology
- Immunology
Background:
- Probiotic strains are live microorganisms used as food supplements for health benefits.
- Health claims range from improved bowel activity to specific pathogen inhibition and immune response modulation.
- Most evidence comes from case reports, uncontrolled human studies, or animal/in vitro research.
Purpose of the Study:
- To review the proposed health benefits and mechanisms of probiotic strains.
- To discuss the importance of strain survival and colonization in the human gastrointestinal tract.
- To highlight the strain-specific nature of probiotic properties and the need for rigorous testing.
Main Methods:
- Review of existing literature on probiotic microorganisms.
- Analysis of proposed mechanisms of action, including antimicrobial effects and immune modulation.
- Discussion of factors influencing probiotic efficacy, such as gastrointestinal survival and colonization.
Main Results:
- Probiotics can exert antagonistic effects on gastrointestinal pathogens.
- They may neutralize food mutagens, alleviate allergic reactions by shifting immune response, and lower serum cholesterol.
- Probiotic bacteria produce antioxidants and antimicrobial substances, and can influence host immune responses.
Conclusions:
- Probiotic strain efficacy is strain-specific and requires thorough testing.
- Survival and colonization of the human gastrointestinal tract are critical for probiotic function.
- Further clinical trials are needed to substantiate many health claims, particularly for allergic diseases.

01:30Bacterial Phylum Actinobacteria
Coryneform bacteria are gram-positive, aerobic, nonmotile rods that exhibit irregular, club-shaped, or V-shaped arrangements. Their V-shape results from snapping division, where the inner cell wall layer forms the cross-wall, while the outer layer remains intact until it ruptures on one side, causing the daughter cells to bend away.The primary genera are Corynebacterium and Arthrobacter. Corynebacterium includes diverse species, ranging from saprophytes to pathogens like Corynebacterium...
01:27Bacterial Phylum Firmicutes
Firmicutes is a diverse phylum of Gram-positive bacteria characterized by a low GC content in their genomes. This phylum includes organisms with monoderm or diderm cell envelopes, highlighting a complex evolutionary history. Firmicutes comprises several major orders, including Lactobacillales, Clostridiales, and Bacillales, which exhibit remarkable diversity in their morphology, metabolism, and ecological roles.The order Lactobacillales includes lactic acid bacteria, which are fermentative...
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. Through...
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...
01:22Probiotics
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...
01:25Production of Organic Acids
Lactic acid, an important organic acid extensively applied in food, pharmaceutical, and biodegradable polymer industries, is primarily produced via microbial fermentation. This method is favored over chemical synthesis due to its environmental sustainability and capacity for enantiomerically pure product formation. Among various microbial processes, the fermentation of starch-based substrates stands out due to the abundance and renewability of raw materials like corn and potatoes.Hydrolysis of...
