ABSTRACT:
A process and apparatus for treating culture medium with a dilute acid such as nitric acid, are disclosed. In a preferred embodiment, nitric acid is sprayed on to a floating oily layer of hydrophobic materials at the surface of a stilled culture rich in aerobic bacteria, which materials can obstruct oxygen take up. The nitric acid surface treats the protective hydrophobic third phase, increasing its surface viscosity and the undesired lipid or oily materials to be readily removed mechanically. Oxygen take up and thence microorganismic growth are promoted. Quite small quantities of dilute acid are effective and leave no toxic residue. An optional embodiment entrains nitrogen dioxide in the aeration gases to form nitric acid in situ for surface treatment of thin oily films occluding bubbles in the culture broth.
