Microbe Identification
Microbe nameBifidobacterium longum
NCBI Taxonomy ID216816
DescriptionBifidobacterium longum DJO10A is a species of bacterium that thrives in a temperature range of 37°C to 45°C, placing it in the mesophilic category. This microbe is a Heterotroph, meaning it requires a pre-existing energy source to survive, as opposed to producing its own energy through photosynthesis. B. longum DJO10A uses fermentation to produce energy, breaking down complex organic molecules and releasing energy through the processes of glycolysis and the citric acid cycle. Gram-stained, B. longum DJO10A displays a characteristic Gram positive staining pattern, indicating the presence of a thick peptidoglycan layer in its cell wall. The bacterium has a rod-shaped morphology, with a length of approximately 0.5-1.5 μm and a width of 0.2-0.5 μm. As a member of the genus Bifidobacterium, B. longum DJO10A can be found in all body sites, including the gastrointestinal tract, oral cavity, and genitourinary tract of humans and animals. It is an Obligate Anaerobe, meaning it cannot survive in the presence of oxygen and will die off quickly if exposed to high levels of O2. In terms of oxygen preference, B. longum DJO10A is a strict anaerobe that requires an oxygen-free environment to thrive. This is likely due to its ability to survive in the lower oxygen environments of the gastrointestinal tract and other body sites. B. longum DJO10A has been shown to have potential health benefits, particularly in the context of gut health and immune modulation. It has been used as a probiotic in certain human studies, demonstrating its ability to colonize the human gut and provide beneficial effects on the host. Furthermore, research has implicated B. longum DJO10A in the regulation of the host's metabolic response to dietary changes, highlighting its importance in maintaining a balanced gut microbiome.
