describe the difference between an obligate halophile and a facultative halophile. An obligate halophile is an organism that requires a high concentration of salt to survive and grow. It cannot tolerate low salt concentrations. On the other hand, a facultative halophile is an organism that can survive and grow in both high and low salt […]

Bacteria that are considered halophiles are capable of growth in salt concentrations greater than 3% A in salt concentrations greater than 7% B in salt concentrations greater than 1% C in salt concentrations greater than 11% Bacteria capable of growth in both 1% and 7% salt concentrations are O considered A obligate halophiles B extreme
