11. Anaerobes utilize electron acceptors from sources other than oxygen gas.12. The species are anaerobes with varying degrees of oxygen tolerance. 13. Anaerobes access oxygen from sources other than the surrounding air.14. Intestinal organisms, especially anaerobes , are commonly cultured from the gallbladder. 15. This motile bacillus is a Gram negative, facultative anaerobe . 16. Anaerobes have been found in infections throughout the human body.17. Anaerobes are able to cause all types of intracranial infections.18. They are aerobes as well as anaerobes and aerotolerant bacteria. 19. However, microaerophiles metabolise energy aerobically, and obligate anaerobes metabolise energy anaerobically. 20. Soil-borne anaerobes are particularly well-adapted to surviving harsh conditions.
