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 edit
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 edit
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:
- denitrificans: Neo-Latin participle adjective denitrificans (from Neo-Latin v. denitrifico), denitrifying.[1]
- nitritireducens: Neo-Latin noun nitris -itis, nitrite; Latin participle adjective reducens, leading back, bringing back and (in chemistry) converting to a different oxidation state; Neo-Latin participle adjective nitritireducens, reducing nitrite.[1]
