Abstract:

The behaviour and state of the envelopes from B. subtilis cultures grown in Luria Bertani (LB) medium with and without 1.5 M NaCl are compared. Under hypertonic conditions, the hydrophobicity of the cultures increases. The phospholipid and fatty acid (FA) compositions show important differences: a higher cardiolipin (CL) content [at the expense of phosphatidylglycerol (PG)], and a higher unsaturated and straight chain FA content. The fluidity of the membranes, determined with fluorescent probes, indicates an increase in viscosity of the cytoplasmic membrane. The consequences of these variations in membrane permeability and osmotolerance are discussed. Copyright (C) 2000 Elsevier Science B.V.
