Question

You inoculate a bacterium into three tubes of nutrient broth medium containing added salt: 0.5% NaCl, 5% NaCl, and 15% NaCl. After incubation, you notice significant turbidity in the 15% NaCl medium and modest turbidity in the 5% NaCl medium. There is no growth in the third tube. This organism would be termed ________.

Answer 1

Halophile.

Step-by-step explanation:

Halophile microorganisms are microorganisms that require very large amounts of NaCl. If the concentration of NaCl is very little, there will be no growth. Ih this case, given that it grows between 5% and 15%, it can be considered a moderate halophile.
