Question

multiple choice question
which name is given to microbes that grow in environments where the ph is lower than 7, such as ph 2?
o mesophiles
o thermophiles
o acidophiles
o neutrophiles
o alkalinophiles

Explanation:

• Mesophiles: Grow at moderate temperatures (20 - 45°C), pH around 7.
• Thermophiles: Thrive at high temperatures (45 - 122°C).
• Acidophiles: Prefer acidic environments (pH < 7).
• Neutrophiles: Optimal growth at pH near 7.
• Alkalinophiles: Grow in alkaline (basic) conditions (pH > 7).

Since the question is about microbes growing in environments where pH is lower than 7 (e.g., pH 2), acidophiles are the correct category.

Answer:

Acidophiles
