Cold adaptation of the Antarctic haloarchaea Halohasta litchfieldiae and Halorubrum lacusprofundi

*Halohasta litchfieldiae* represents ∼ 44% and *Halorubrum lacusprofundi* ∼ 10% of the hypersaline, perennially cold (≥ −20°C) Deep Lake community in Antarctica. We used proteomics and microscopy to define physiological responses of these haloarchaea …

Morphological and proteomic analysis of biofilms from the Antarctic archaeon, Halorubrum lacusprofundi

Biofilms enhance rates of gene exchange, access to specific nutrients, and cell survivability. Haloarchaea in Deep Lake, Antarctica, are characterized by high rates of intergenera gene exchange, metabolic specialization that promotes niche …
