Abstract: | Increased listerial barotolerance at elevated osmolarity is attributed, in part, to the presence of accumulated betaine and L-carnitine. The percentage of listerial survival following exposure to 400 MPa for 5 min increased from 0.008 to 0.02% with added L-carnitine (5 mM) and to 0.05% with added betaine (5 mM). Furthermore, listerial cells incapable of transporting compatible solutes fail to adapt to high pressure at elevated osmolarity. |
