FIG 1.

(A) Survival of A. muciniphila after exposure to oxygen over time. A survival rate of 1% was measured during 48 h of exposure to ambient air (dashed line), while >90% were still viable in anaerobic cultures (solid line). Points depict averages of results of 4 replicates. (B) Growth of A. muciniphila in the tube assay. Left: an A. muciniphila-inoculated tube. Right: a control tube. The lower line indicates the resazurin-oxidized zone in the control tube; the upper line indicates the reduced oxidized zone in the tube where A. muciniphila was growing. A picture representative of 4 repeats is shown.
