if a bacteria is allowed to grow for several generation in very low temperature then there is increase in the content of the glycolipid in the the cell wall of the bacteria.
Option 4
Explanation:
- That glycolipid helps the bacteria to live in the extreme cold temperature. The amount of glycolipid is different in different types of bacteria.
- On the basis of amount of glycolipid present in the cell wall the bacteria can only be divided into gram positive and gram negative bacteria.
- The bacterial growth usually follows sigmoid shaped curve.
