5. Microbes that are classified as psychrophiles live in extremely cold conditions. The bacterium Psychromonas ingrahamii, which lives in the ice of the Arctic Ocean at a frigid -20C, holds the record in terms of bacteria growth at low temperatures. Microbes that live in such extreme conditions have a variety of adaptations; changes in membrane lipids and the cell's proteins are especially important adaptations. What adaptations would you suspect this bacterium has regarding its membrane fatty acids that help maintain mem- brane fluidity in such cold conditions? Provide a possible explana- tion as to why most enzymes from these bacteria do not function at room temperature.
