Description and significance
The bacterium, Bacteroides coprophilus are one of many micro bacteria from the phylum Bacteriodetes, which are the predominant bacterial organisms within the mammalian digestive system .
The bacterium consists of a linear genome with 3,855,443 nucleotide base pairs, 3,906 genes, and 3,838 proteins [6,7].
Cell and colony structure
B. coprophilus cells are bacilli shaped with 0.7-0.8x2.5-4.1μm in dimension. The organism’s colonies are 0.5-1.2mm in diameter and are translucent, circular, convex, and dark gray .
The bacterium are gram-negative, mesophilic, they maintain a strict obligate anaerobe, non-motile, and non-spore forming life. Optimal temperature is mammalian diet dependent, within the range of 34-37°C.
B. coprophilus thrives in a habit that contains 85% H20, 10% bile salts, 3% mucus, 1% fat, 0.7% inorganic salts, and 0.3% cholesterol, which corresponds to normal properties of mammalian stomach bile[3,2]. The bacterium also enjoys a pH within the range of 3-4, which can be maintained by the presence of HCl within the mammalian host gut. The bacterium also enjoys a habitat rich in undigested polysaccharides’ that host enzymes were unable to degrade.
Currently research to understand how B.coprophilus, and other bacterium within the phylum Bacteroidetes, affect digestion and obesity are underway. Research so far has indicated that a digestive system rich with bacterium from the phylum Bacteroidetes correlates with weight lose and lean body mass of rats.
