| Description | Bifidobacterium coryneforme is a gram-positive, rod-shaped bacterium that thrives in anaerobic environments, preferring a mesophilic temperature range of 30–37°C. This microbe is classified as a chemoheterotroph, relying on organic compounds for its energy and carbon needs. Bifidobacterium coryneforme is predominantly found in the human gastrointestinal tract, where it plays a crucial role in maintaining gut health, as well as in other body sites, including the oral cavity and the vagina. It is an obligate anaerobe, meaning it requires an oxygen-free environment to survive and metabolize effectively. The gram-positive nature of Bifidobacterium coryneforme indicates the presence of a thick peptidoglycan layer in its cell wall, conferring protection against environmental stresses and antibiotics. Its rod shape contributes to its efficient colonization in the gastrointestinal tract, where it competes with pathogenic microorganisms. The mesophilic temperature preference aligns with human body temperature, facilitating optimal growth and activity within the host. As a chemoheterotroph, Bifidobacterium coryneforme derives energy from fermenting dietary fibers and other complex carbohydrates, producing short-chain fatty acids that are beneficial for colonic health. The obligate anaerobic characteristic enables it to flourish in the gut’s low-oxygen environment, where it thrives alongside other beneficial microbes, contributing to a balanced microbiota. Bifidobacterium coryneforme has been studied for its potential probiotic benefits, including the enhancement of immune response, suppression of pathogenic bacteria, and improvement of lactose digestion. Its presence is often associated with a healthy microbiome and overall well-being, highlighting its significance in human health. This microbe has attracted attention in the field of functional foods and dietary supplements, underscoring its relevance in modern microbiological research and applications. |
