Cell Structure, Metabolism and Life Cycle
Lactobacillus reuteri is a Gram-positive rod that forms chain arrangements and does not produce endospores. Some strains have also been shown to form relatively thin biofilms (5-7µm thick.) [1] L. reuteri is a mutualistic host-associated microbe, living in the guts of animals. As such, it requires a host habitat and is a mesophilic, facultative anaerobe with a preference for acidic environments. L. reuteri is an obligate heterofermentative microbe, producing carbon dioxide, ethanol, acetate, and lactic acid from glucose fermentation. It can also anaerobically metabolize glycerol, producing the antimicrobial reuterin (3-hydroxypropionaldehyde). [2] L. reuteri has also been shown to produce folate and cobalamin, also known as vitamin B12, nutrients that many animals, including humans, require.
Ecology and Pathogenesis
Habitat; symbiosis; biogeochemical significance; contributions to environment.
If relevant, how does this organism cause disease? Human, animal, plant hosts? Virulence factors, as well as patient symptoms.
