Methylosphaera hansonii

Methylosphaera hansonii, also called Antarctic budding methanotroph AM6,[1] is a species of psychrophilic, group I methanotrophs, named after microbiologist Richard S. Hanson.[2] It is non-motile, coccoidal in morphology, does not form resting cells, reproduces by constriction, and requires seawater for growth. Its type strain is ACAM 549.

Scientific classification
Domain: Bacteria
Phylum: Proteobacteria
Class: Gammaproteobacteria
Order: Methylococcales
Family: Methylococcaceae
Genus: Methylosphaera
Species:
M. hansonii
Binomial name
Methylosphaera hansonii
J.P.Bowman et al. 1997

The cells are round and 1.5–2.0 μm in diameter. They are Gram-negative, non-motile, and strictly aerobic. They use methane and methanol as substrates to produce energy, and they can fix atmospheric nitrogen.[3]

Nomenclature

The name has French and Greek roots. Methyl for its methyl group and sphaera for sphere. Overall the name means "methyl sphere."[3]
