1. This motile bacillus is a gram negative, facultative anaerobe and a spirochaete. 2. Strain CKB is a Gram negative, facultative anaerobe belonging to the Betaproteobacteria. 3. Chlorhexidine is active against Gram-negative organisms, facultative anaerobes , aerobes, and yeasts. 4. This is observable when facultative anaerobes are cultured in thioglycollate broth. 5. "Victavallis vadensis " is a facultative anaerobe , like most gut microbes. 6. And facultative anaerobes can grow without oxygen but use oxygen if it is present. 7. Many facultative anaerobes use denitrification because nitrate, like oxygen, has a high reduction potential. 8. It is a facultative anaerobe , it can therefore use alcoholic respiration in aerobic conditions. 9. Vibrionaceae are Gram-negative organisms and facultative anaerobes , capable of flagella, which are generally polar. 10. It is a facultative anaerobe capable of aerobic respiration.
