Can bacteria synthesize their own growth factors?
Click to flip
Some bacteria can synthesize their own growth factors, while others require them from external sources.
Click to flip
What is the difference between autotrophic and heterotrophic microbes in terms of growth factor requirements?
Click to flip
Autotrophic microbes synthesize their own growth factors; heterotrophic microbes obtain them from the environment.
