skein of filaments

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 as can be seen here and are visible with the naked eye as white wispy threads.
