Anaerobic organisms require an oxygen free environment. When culturing anaerobic microbes, broths are often flushed with nitrogen gas to extinguish oxygen present, and growth can also occur on media in a chamber without oxygen present. Sodium resazurin can be added to indicate redox potential. Cultures are to be incubated in an oxygen free environment for 48 hours at 35oC before growth is examined

Anaerobic bacteria collection can come from a variety of sources in patient samples, including blood, bile, bone marrow, cerebrospinal fluid, direct lung aspirate, tissue biopsies from a normally sterile site, fluid from a normally sterile site (like a joint), dental, abscess, abdominal or pelvic abscess, knife, gunshot, or surgical wound, or severe burn.
