Question 14 • Earth and Space Science

Why might microbes that produce surfactant vesicles show higher pollutant degradation than microbes that rely only on oxygenase or dehydrogenase enzymes?

Answer
A
Surfactant vesicles increase the pH of the water, making hydrocarbons dissolve instantly.
B
Surfactant vesicles break oil into smaller droplets, giving enzymes more surface area to act on.
C
Surfactant vesicles reduce the need for oxygen in microbial metabolism.
D
Surfactant vesicles directly convert hydrocarbons into water without enzymes.
