marcescens has a single circular chromosome that is signature to many bacterial species. Several partial sequences of 16S ribosomal RNA have been analyzed and are indicated as linear strands. The entire genome has not been sequenced so the complete size and contents of the genome are unknown along with number of chromosomes. Limited information can be found on the genome of Serratia liquefaciens. It is also a pathogenic bacterium that has been associated with severe nosocomial infections. Thus far, it has been proven to have certain antifungal properties in a plantвЂ™s rhizosphere.

However, current research is taking place on its mechanisms and pathogenic affects. ДЇollowing the genus change, little can be found regarding S. marcescens and the genus was changed to Serratia. liquefaciens was determined to be more closely related to S. In fact, up until 1971, it was actually characterized as Enterobacter liquefaciens.

Not much is actually known about Serratia liquefaciens. liquefaciens is not a normal component of human fecal flora. 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. They can inhabit both aerobic and anaerobic environments. liquefaciens are facultative anaerobes making oxygen inessential to survival. Serratia species are usually motile and contain peritrichous flagella. liquefaciens is a straight rod shaped bacterium with a diameter of 0.5-0.8 Ојm, a length of 0.9-2.0 Ојm, and is Gram negative.
