Question

Which group of microorganisms is most likely to spoil a freshwater trout preserved with salt? A) Psychrophiles B) Facultative halophiles C) Anaerobes D) Thermophiles E) Hyperthermophiles

Answer 1

The right option is; B. Facultative halophiles

Facultative halophiles are the group of microorganisms that is most likely to spoil a freshwater trout preserved with salt because they can survive, grow and reproduce in extremely salty environments. Facultative halophiles can also survive and reproduce at not-high salt concentrations as they do not rely on high salt concentrations for growth. Examples of facultative halophiles are Staphylococcus aureus and Streptococcus spp.
