Pseudomaricurvus
Pseudomaricurvus is a genus of Gram-negative, aerobic, rod-shaped marine bacteria in the family Cellvibrionaceae. Members of the genus have been isolated from seawater and tidal-flat sediments. Individual species can degrade compounds including nonylphenol, aliphatic hydrocarbons, and carboxymethyl cellulose.
Taxonomy
The generic name combines the Greek adjective pseudês, meaning false, with the bacterial genus name Maricurvus. The type species is Pseudomaricurvus alkylphenolicus.
A genome-based revision found that species classified in Aestuariicella formed a well-supported group with Pseudomaricurvus in phylogenies based on 16S rRNA genes, RpoB protein sequences, and core genes. Aestuariicella is consequently treated as a heterotypic synonym of Pseudomaricurvus.
The List of Prokaryotic names with Standing in Nomenclature recognizes four species with validly published and correct names:
- Pseudomaricurvus albidus, formerly Aestuariicella albida
- Pseudomaricurvus alcaniphilus
- Pseudomaricurvus alkylphenolicus
- Pseudomaricurvus hydrocarbonicus, formerly Aestuariicella hydrocarbonica
Characteristics and ecology
The type strain of P. alkylphenolicus was isolated from seawater collected near the Ogasawara Islands of Japan and can degrade para-nonylphenol.
The type strain of P. alcaniphilus was isolated from tidal-flat sediment in Taean Province, South Korea. It is motile and can degrade carboxymethyl cellulose.
The type strain of P. hydrocarbonicus was isolated from a sea tidal flat in Dangjin Bay, South Korea. It is non-motile and can degrade a range of aliphatic hydrocarbons. Growth was observed at sodium chloride concentrations of up to 10% by weight.
The type strain of P. albidus was isolated from surface water of the Yellow Sea. It is aerobic, non-motile, and oxidase-positive.
