ABSTRACT:
A process for the aerobic biological break-down of substances having low water solubility in an aqueous medium, and a microorganism, Bacillus thermoleovorans strain DSM 10561 and an enzyme obtained therefrom are disclosed. The microorganism is suitable for use in the disclosed process wherein the bioavailability of the substances to be broken down is raised by setting the temperature of the aqueous medium to 45 degrees Celisus and higher. The microorganism is used to break-down the substances having low water solubility.
