S. oligofermentans

Webpetitive advantages of S. oligofermentans over the caries patho-gen Streptococcus mutans. Of note, So-aqpA orthologs with the functionally important Phe-40 are present in all streptococci. Our work has uncovered an intrinsic, H 2 O 2-inducible bacterial peroxiporin that has a key physiological role in H 2 O 2 detoxifi-cation in S. oligofermentans. WebSeveral growth conditions were examined in the model, namely: S. oligofermentans was inoculated 24 h before S. mutans or vice versa; the growth medium was supplemented with 0.2% sucrose or 0.4% glucose; biofilms were grown under a constantly neutral pH or pH-cycling condition, which included 8 h of neutral pH and 16 h of pH 5.5.
