Question

which of the following pairs of microbe classification terms and optimal growth temperatures is mismatched? thermophile- growth at 30 - 50c hyperthermophile- growth at 80 - 110c mesophile- growth at 25 - 40c psychrotroph- growth at 20 - 30c question 12 (bonus) (1 point) which type of microorganism can survive in the absence of oxygen but prefers to use oxygen when it is available? aerotolerant anaerobe microaerophile facultative anaerobe obligate anaerobe

Explanation:

1. Thermophiles grow optimally at temperatures above 50°C, not 30 - 50°C. Hyperthermophiles grow at 80 - 110°C, mesophiles at 25 - 40°C, and psychrotrophs at 20 - 30°C.
2. Facultative anaerobes can survive without oxygen via fermentation or anaerobic respiration but prefer to use oxygen for aerobic respiration when it is available. Aerotolerant anaerobes are indifferent to oxygen, microaerophiles need low - levels of oxygen, and obligate anaerobes are killed by oxygen.

Answer:

Question 11: thermophile- growth at 30 - 50C
Question 12: facultative anaerobe
