Giant aquatic bacterium is a master of adaptation

The largest freshwater bacterium, Achromatium oxaliferum, is highly flexible in its requirements, as researchers have now discovered: It lives in places that differ extremely in environmental conditions such as hot springs and ice water. The adaptation is probably achieved by a process which is unique to these bacteria: only relevant genes are enriched in the genomes and transcribed, while others are archived in cell compartments.
