Species

Bacteroides thetaiotaomicron

Description and significance

Bacteroides thetaiotaomicron, a Gram negative anaerobic microbe, resides in and dominates the human intestinal tract . It consists of a 4779 member proteome containing the structural means to bring in and hydrolyze non-digestible polysaccharides as well as an environment sensing mechanism consisting of outer membrane proteins. Initially isolated from fecal matter, Bacteroides thetaiotaomicron has great importance in terms of the study of the symbiotic bacteria-host relationships within the human intestine as well as for its digestive abilities and potential breakdown of digested plants.
