Summary
Enterococci from commercial feeds were analyzed for probiotic potential. Enterococcus faecium strain EE3 demonstrated promising probiotic properties, suggesting its use as a feed additive.
Area of Science:
- Microbiology
- Probiotics
- Animal Feed
Background:
- Enterococci are common in commercial feeds.
- Assessing their probiotic potential is crucial for feed applications.
Purpose of the Study:
- To identify Enterococci strains from commercial feeds.
- To evaluate their probiotic characteristics for potential use as feed additives.
Main Methods:
- Isolation and identification of Enterococci from 28 commercial feeds.
- Species identification using tRNA-PCR and capillary electrophoresis.
- Assessment of probiotic traits including adherence, lactic acid production, bile tolerance, and antimicrobial activity.
Main Results:
- Six strains identified as Enterococcus faecium, four as E. faecalis, and one as E. hirae.
- All strains exhibited sensitivity to vancomycin, ampicillin, tetracycline, and rifampicin.
- Strains showed adherence to intestinal mucus, produced lactic acid, and survived in Oxgall-bile; no antimicrobial activity was detected.
Conclusions:
- Enterococcus faecium strain EE3 possesses significant probiotic properties.
- Strain EE3 is a potential candidate for a feed additive.
- Further research may explore its efficacy in animal nutrition.

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...
01:27Microbiota of the Large Intestine
The large intestine hosts the most densely populated microbial ecosystem in the human body. This complex community primarily consists of anaerobic bacteria, with Bacillota (formerly Firmicutes) and Bacteroidota (formerly Bacteroidetes) as the predominant groups. The distribution of these microbes varies along different sections of the large intestine, influenced by local environmental factors such as oxygen availability and nutrient composition.The cecum, located at the beginning of the large...
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. 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...
