General information
Name
Subsaxibacter broadyi
Valid publication
2005
Nomenclature type
ACAM 1064;CIP 108527;P7
Etymology
N.L. gen. masc. n. <i>broadyi</i>, of Broady, named in honour of P.A. Broady, Antarctic microbiologist from New Zealand who pioneered the study of many Antarctic terrestrial biomes.
Ecology
Source
isolated from cyanobacterial biofilms attached to the undersides of partially buried quartz stones, found in the Vestfold Hills, an ice-free region of East Antarctica.
Morphology
Cells are non-spore-forming, coccobacilli (0.3-0.5 × 0.4-1.0 µm), and motile by gliding. Cell mass is orange. Flexirubin pigments are not formed. Do not form resting cells. Colonies are small (<1 mm), circular and convex, with a spreading or entire edge and a butyrous to viscid consistency on MA. Colonies exhibit spreading margins on dilute media.
