Biofilm containing Alteromonas sp. and diatom Navicula incerta, from Rivas & Riquelme (2012).

Belongs within: Chromatibacteria.
Contains: Pseudoalteromonas.

The Alteromonadaceae are a group of marine gamma-Proteobacteria defined on phylogenetic grounds.

Characters (from Ivanova & Mikhailov 2001): Gram-negative, rod-shaped bacteria. Motile by single flagellum, sometimes sheathed, occasionally forming lateral flagella, fimbria or other sheath-like structure. Not forming endospores or microcysts; sometimes forming capsules. Requiring Na+-ions for growth; sometimes capable of growth in media containing 15% salts. Chemoorganotrophs; oxygen used as electron acceptor. Aerobic or facultatively anaerobic. Usually not denitrifying; arginine dehydrolase absent. Usually utilising glucose, fructose, not utilising mannose. Major isoprenoid quinone usually Q8. Major fatty acids i15:0, 16:0, 16:1 (n-7). G+C content of DNA ranging from 35–50%.
