We investigated the influence of cell hydration on the ability of Saccharomyces cerevisiae CBS 1171 to withstand extreme hydrostatic pressure in order to determine the mechanisms involved in cell resistance. Hydration conditions were modified in two different ways. We first modulated the chemical potential of water by adding glycerol in cell suspensions. Another procedure consisted in dehydrating cells aerobically and immersing them in perfluorooctane, an innocuous hydrophobic liquid used as a… CONTINUE READING
