Species

Nisaea is a genus in the phylum Pseudomonadota (Bacteria), [2] which contains two [3] species, namely N. denitrificans and N. nitritireducens , which were described in 2008. [1]

Description

Like all Proteobacteria the two species stain Gram-negative.(, [1] cf. [4] ) They were isolated from coastal, surface waters of the north-western Mediterranean Sea, specifically in February 2004 at the SOLA station located in the bay of Banyuls-sur-Mer (42 2.99 N 3 0.89 E) at a depth of 3 metres. [1] The cells are motile pleomorphic rods that are 2.9 μm long and 0.9 μm wide. [1] When grown on marine agar medium, they form cream colonies (i.e. no pigmentation). Apart from standard genetic differences for species (98% 16S, 55% DNA-DNA), the two species differ in that Nisaea denitrificans can fully denitrify whereas Nisaea nitritireducens cannot only reduce nitrite. [1]

Etymology

The name Nisaea derives from:
Latin feminine gender noun Nisaea, nymph of the sea, referring to the marine origin (Mediterranean sea). [1] Nicaea is in fact a sea nymph and daughter of the river-god Sangarius and Cybele. Whereas the specific epithets, refer to:
