Shewanella frigidimarina
Description and Significance
S. frigidimarina is a bacterial species that is motile, gram-negative, and rod-shaped. This psychrophilic species inhabits a variety of habitats on the coast of Antarctica (Bozal et al., 2002). It is important to humans because of potential biomedical applications and to the environment because of its use in bioremediation (Sani et al., 2009).
Genome Structure
The genome is made up of about 4.8 million base pairs, with about 41% of that consisting of G & C. This genome exists within a single circular chromosome, although some extrachromosomal plasmids are present. It is very plastic due to the large abundance of mobile genetic elements (MGE) used to evolve and adapt (Di Noto et al., 2016).
Cell Structure, Metabolism and Life Cycle
S. frigidimarina is gram-negative, rod-shaped, and contains one unsheathed polar flagellum for motility. Young colonies are circular and mucoid, while older colonies can sometimes become filamentous. This species is chemo-organotrophic, exhibiting anaerobic growth while using reduction of ferric compounds (with DL-Lactate as the electron donor) and fermentation of carbohydrates to gain energy (Bozal et al., 2002). It produces polyunsaturated fatty acids that have potential applications in health care and bioremediation of environments affected by petroleum hydrocarbons (due to events like fuel leaks) (Sani et al., 2009).
