Serratia liquefaciens
Description and significance
S. liquefaciens is a straight rod shaped bacterium with a diameter of 0.5-0.8 μm, a length of 0.9-2.0 μm, and Gram negative. Gram negative organisms have a thinner layer of peptidoglycan surrounded by an inner and outer membrane. Serratia species are usually motile and contain peritrichous flagella. [Bergey’s Manual of Determinative Bacteriology:9th edition p.187]
S. liquefaciens are facultative anaerobes making oxygen inessential to survival. They can inhabit both aerobic and anaerobic environments. Thus, S. liquefaciens is a widespread bacteria found in the environment and capable of colonizing on soil, water, plants, and the digestive tracts of rodents, insects, fish, and humans.[2] However, it must be noted that S. liquefaciens is not a normal component of human fecal flora.
