filaments

Description:

Hydrogenobacter acidophilus (high-dro-jen-owe-back-ter ass-sid-off-ill-us) is found at some of the hottest regions, often above 60 degrees C. In nature, it takes the forms of filaments which collect together and are visible with the naked eye as white wispy threads. The bacterial filaments have denser inclusions. Phase contrast.
