reduced growth rate at higher temperatures, addition of 1 mM glycine betaine, homobetaine, carnitine, butyrobetaine, crotonobetaine, DMSP, choline, or glutamate have a clear thermoprotective effect at 52°C, heat protectants are taken up under heat stress via the OpuA, OpuC, and OpuD transporters, despite the strongly reduced glycine betaine transport rate at 52°C, substantial glycine betaine accumulation, but it is not increased in comparison to cells grown at 37°C, thermoprotection by glutamate does not depend on an increased cellular pool of this amino acid
