Facultative halophile
WebA halophile is a microorganism that can survive and replicate in a high salt concentration environment (high osmotic pressure). Obligate halophiles are microorganisms that can only survive in high salt concentration environments. Facultative halophiles are able to survive in both high and normal salt concentration environments. WebFacultative halophiles: Most microoganisms are inhibited by high-salt conditions, but facultative halophiles are microorganisms that can grow and reproduce under high-salt conditions. In contrast, to obligate halophiles, which require high-salt conditions, facultative halophiles do not require high-salt conditions but neither are they inhibited ...
