Answer:

Thermophilic bacteria adjust the fluidity of their plasma membrane by increasing the distinct fatty acids and polar carotenoid content.

Explanation:

Thermophilic bacteria adjust fluidity of their plasma membrane by increasing the following content in it;

  • Branched iso-fatty acids
  • Long-chain fatty acids
  • Saturated fatty acids
  • Polar carotenoid content

Interestingly, the thermophilic bacteria that grow above 70°C possess lipid species such as diether, tetraethers, and tetra esters.

Bacteria are prokaryotic organisms, which can survive in extreme temperatures. The bacteria that live in the hot springs are thermophile bacteria.

Thermophile bacteria adjust the fluidity of the plasma membrane by increasing the fatty acids and polar carotenoid content.

The bacteria adjust the fluidity of the plasma membrane by:

  • regulating the ratio of unsaturated fatty acids to saturated
  • levels of cyclopropane fatty acids
  • polar carotenoid content

Thus, the bacteria adjust the fluidity of the plasma membrane by fatty acids content.
