Alteromonas
Encyclopedia
Alteromonas is a genus of Proteobacteria
Proteobacteria
The Proteobacteria are a major group of bacteria. They include a wide variety of pathogens, such as Escherichia, Salmonella, Vibrio, Helicobacter, and many other notable genera....

 found in sea water, either in the open ocean or in the coast
Coast
A coastline or seashore is the area where land meets the sea or ocean. A precise line that can be called a coastline cannot be determined due to the dynamic nature of tides. The term "coastal zone" can be used instead, which is a spatial zone where interaction of the sea and land processes occurs...

Gram-negative
Gram-negative bacteria are bacteria that do not retain crystal violet dye in the Gram staining protocol. In a Gram stain test, a counterstain is added after the crystal violet, coloring all Gram-negative bacteria with a red or pink color...

. Its organelles consist of curved rods and a single polar flagellum
Flagellum
A flagellum is a tail-like projection that protrudes from the cell body of certain prokaryotic and eukaryotic cells, and plays the dual role of locomotion and sense organ, being sensitive to chemicals and temperatures outside the cell. There are some notable differences between prokaryotic and...

Etymology

The etymology of the genus is L. adj. alter -tera -terum, another, different; L. fem. n. monas (μονάς / μονάδα)
-monas
The suffix -monas is used in microbiology for many genera and is intended to mean "unicellular organism".-Meaning:The suffix -monas is used in microbiology for many genera in a similar way to -bacter, -bacillus, -coccus or -spirillum...

, a noun with a special meaning in microbiology used to mean unicellular organism; N.L. fem. n. Alteromonas, another monad.

Members of the genus Alteromonas can be referred to as alteromonads (viz. Trivialisation of names).

Authority

The genus was described by Baumann et al. in 1972, but was emended by Novick and Tyler 1985 to accommodate Alteromonas luteoviolacea (now Psuedoalteromonas luteoviolacea), Gauthier et al. 1995, who split the genus in two (Pseudoalteromonas
