Major Microbial Habitats Flashcards
Give an example of medically relevant biofilm that forms in virtually all healthy humans.
Dental plaque.
Why might a biofilm be a good habitat for bacterial cells living in a flowing system?
It prevents cells to be washed away due to liquid flow
What is a microbial mats?
It’s a very thick biofilm that is formed in extreme environments.
How would aerobic bacteria respond to changing oxygen concentration over a diel cycle?
They can migrate to the surface during the night when the mat becomes anoxic.
Which phylum of Bacteria dominates soil bacterial diversity?
Proteobacteria.
What factors govern the extent and type of microbial activity in soils?
Water and resources avaiability.
Which region of soil is the most microbially active?
In the organo-rich soil surfaces layers, especially around the rhizosphere.
