You inoculate the bacterium into 3 tubes of nutrient broth medium containing salt--0.5% NaCl,5% NaCl,and 15% NaCl.After incubation,you notice that the organism is growing very well in the 15%,and somewhat in the 5%.There is no growth in the third tube.This organism would be called:

Question

Quizplus · Accepted Answer

Halophilic organisms are those that thrive in high-salt environments, such as the 15% NaCl medium in which this bacterium is growing very well. The lack of growth in the 0.5% NaCl medium suggests that this organism is unable to tolerate low salt concentrations, ruling out osmophobic. Barophilic refers to organisms that thrive under high pressure, which is not relevant to this scenario. Haloduric refers to organisms that can survive in high salt concentrations but do not necessarily require them for growth, which does not fully describe the behavior of this organism in the 15% NaCl medium.
