| Description | Bifidobacterium pseudocatenulatum is a gram-positive, rod-shaped bacterium that thrives in a thermophilic environment, characterized as mesophilic, with a temperature preference range of 25-45°C. As a heterotroph, it obtains its energy by breaking down complex organic molecules, specifically by fermenting carbohydrates and peptides. This microbe produces ATP through anaerobic fermentation of glucose, yielding lactate, acetate, and formate as byproducts. Bifidobacterium pseudocatenulatum is a ubiquitous microbe, colonizing various body sites, including the oral cavity, gut, vagina, and skin, in all species of mammals. It is an obligate anaerobe, unable to survive in the presence of oxygen, which necessitates the development of specialized membrane-bound enzymes to facilitate anaerobic metabolism. One of the distinctive features of Bifidobacterium pseudocatenulatum is its ability to produce various bioactive compounds, including conjugated linoleic acid, which exhibits immunomodulatory effects. Additionally, it has been associated with the production of antimicrobial peptides, contributing to its ability to inhibit the growth of pathogenic bacteria. In the context of human health, Bifidobacterium pseudocatenulatum is considered a beneficial microbe, playing a crucial role in maintaining gut homeostasis and immune system development. Furthermore, it has been linked to the alleviation of symptoms in patients suffering from irritable bowel syndrome (IBS), inflammatory bowel disease (IBD), and other gastrointestinal disorders. |
