The cell wall is the main effective component of BB68 on nematode longevity. (A) Feeding worms the cell wall (CW) of BB68 (0.12 mg and 1.2 mg per plate) significantly increased the lifespan of nematodes relative to feeding them OP50 CW (0.12 mg per plate). (B) Feeding worms cell wall-free extracts (CFE) of BB68 did not affect the lifespan of nematodes relative to the lifespan of nematodes fed OP50 CFE.
