title: Proteins and acids from petroleum.
abstract: The wax distillate fraction (boiling range 300 up to 400 degrees C) from the crude oil "El-Alameen" was found to be a good substrate for the biosynthesis of proteins and/or amino acids by bacteria under special culture conditions. The fermentation processes were accompanied by a refining effect to the oil fraction, elevating its refraction index and lowering its melting point, giving dewaxing effect to the oil fraction.
