ABSTRACT
The storage in the laboratory of hydrocarbon degrading bacteria to be used in the decontamination of polluted sites or in the enhancement of biological treatment of industrial effluents was studied. Storage was carried out at 4 degrees C in nutrient agar and in a medium with selection pressure, liquid mineral medium with hydrocarbons. Storage at 4 degrees C with selection pressure and storage at -20 degrees C of 7 gram negative bacilli were compared. The former was the easiest method for preserving the greatest number of strains viable and active.

ABSTRACT
A study was made of the elimination of fosfomycin by the membrane of the artificial kidney in 10 patients with hemodialysis and a creatinine clearance of less than 5 ml/min. To do so we determined the half-life, the dialysance, the percentage of total loss and the percentage of loss by the artificial kidney. We reached the conclusion that fosfomycin is heavily dialyzed (D = 64 ml/min), it is entirely eliminated by the kidneys and its half-life is therefore affected very little (an increase of only about 30 min is produced). All of this leads to a practical schema by which the entire initial dose should be replenished at the end of each dialysis.
