associated with sulphur

描述：

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 whiteness in part is due to the inclusion of crystallized sulphur,. The bacteria form intimate association with the sulphur,, and a number of rod shaped cells can be seen adhering to it.
