The effect of different drying techniques on the bioremediation properties of a strain selected for its drought resistance characteristics was studied. The lyophilisation process does not affect its ability to grow on xenobiotic compound when measured right after drying. However, when stored at 25 degrees C for 15 days, a loss of bioremediation properties appears. An accelerated storage test shows that the rate of loss of the biodegradation properties is higher than the rate of loss of survival and that there is a critical storage temperature under which the activity is fully maintained.
