Proteobacteria is a major phylum of Gram-negative bacteria. They include a wide variety of pathogenic genera, such as Escherichia, Salmonella, Vibrio, Helicobacter, Yersinia, Legionellales, and many others. Others are free-living (nonparasitic) and include many of the bacteria responsible for nitrogen fixation.
Sea slug is a common name for some marine invertebrates with varying levels of resemblance to terrestrial slugs. Most creatures known as sea slugs are actually gastropods, i.e. they are sea snails that over evolutionary time have either completely lost their shells, or have seemingly lost their shells due to having a greatly reduced or internal shell. The name "sea slug" is most often applied to nudibranchs, as well as to a paraphyletic set of other marine gastropods without obvious shells.
The Rhizobiaceae is a family of proteobacteria comprising multiple subgroups that enhance and hinder plant development. Some bacteria found in the family are used for plant nutrition and collectively make up the rhizobia. Other bacteria such as Agrobacterium tumefaciens and A. rhizogenes severely alter the development of plants in their ability to induce crown galls or hairy roots found on the stem. The family has been of an interest to scientists for centuries in their ability to associate with plants and modify plant development. The Rhizobiaceae are, like all Proteobacteria, Gram-negative. They are aerobic, and the cells are usually rod-shaped. Many species of the Rhizobiaceae are diazotrophs which are able to fix nitrogen and are symbiotic with plant roots.
Parvularcula bermudensis is a marine bacterium which was identified in 2003 in the western Sargasso Sea in the Atlantic Ocean. It forms a deep branch in the Alpha Proteobacteria, distinct from the other orders.
The Aurantimonadaceae are a small family of marine bacteria. Six species are known. Aurantimonas coralicida causes a white plague in corals. Fulvimarina pelagi was isolated from seawater, and takes the form of nonmotile rods.
Fulvimarina is a genus of bacteria from the family of Aurantimonadaceae.
Epsilonproteobacteria are a class of Proteobacteria. All species of this class are, like all Proteobacteria, Gram-negative.
Jeotgalicoccus is a genus of Gram-positive, facultatively anaerobic, and halotolerant to halophilic bacteria. The cells are coccoid. The genus is named after the Korean fish sauce jeotgal, whence these bacteria were first isolated.
Cohaesibacter is a genus of bacteria from the family of Brucellaceae.
Algoriphagus is a genus in the phylum Bacteroidetes (Bacteria).
The Nautiliaceae are a family of bacteria placed in an order to itself, Nautiliales, or in the order Campylobacterales. The members of the family are all thermophilic. They are:
Virgibacillus is a genus of Gram-positive, rod-shaped (bacillus) bacteria and a member of the phylum Firmicutes. Virgibacillus species can be obligate aerobes, or facultative anaerobes and catalase enzyme positive. Under stressful environmental conditions, the bacteria can produce oval or ellipsoidal endospores in terminal, or sometimes subterminal, swollen sporangia. The genus was recently reclassified from the genus Bacillus in 1998 following an analysis of the species V. pantothenticus. Subsequently, a number of new species have been discovered or reclassified as Virgibacillus species.
Aureimonas frigidaquae is a Gram-negative, catalase- and oxidase-positive, facultatively anaerobic bacteria from the genus of Aurantimonas which was isolated from a water-cooling system in Gwangyang in the Republic of Korea. Aurantimonas frigidaquae was reclassified to Aureimonas frigidaquae.
Aureimonas ureilytica is a bacterium from the genus of Aurantimonas. Aurantimonas ureilytica was reclassified to Aureimonas ureilytica.
The Natranaerobiales are an order of bacteria placed within the class Clostridia. This order contains the thermophilic bacterial species Natranaerobius thermophilus and the related species Natranaerobaculum magadiense.
