Membrane and Extracellular Matrix Glycopolymers of Colwellia psychrerythraea 34H: Structural Changes at Different Growth Temperatures
Colwellia psychrerythraea 34H is a marine Gram-negative psychrophile; it was isolated from Arctic marine sediments, but it is considered cosmopolitan in cold environments. This microorganism is considered a model to study adaptive strategies to sub-zero temperatures, and its lifestyle has been the o...
