Other commonly encountered …PSA was purified from B. fragilis mutant strain Δ44 and LOS was purified from an acapsular B. fragilis mutant strain by phenol-water extraction as previously described (Tzianabos et al., 1992). To obtain the purified delipidated polysaccharide domain of PSA, PSA was subjected to acid hydrolysis with 2% acetic acid at 90°C for 2 h.To confirm the mucin-degrading capacity of B. vulgatus, B. fragilis, and B. thetaiotaomicron, we grew B. vulgatus ATCC 8482, B. fragilis MGH 10513 and B. thetaiotaomicron ATCC 29148 in ZMB1 with ... ….
