Analytical monitoring:
no

Test solutions

Details on test solutions:
For the purpose of the definitive study the test material was prepared by a direct dispersion in sterile reverse osmosis water.

Test organisms

Test organisms (species):
Pseudomonas putida
Details on inoculum:
The test was carried out using Pseudomonas putida strain NCiB 8248. Freeze dried cultures of Pseudomonas putida were obtained from the National Collection of Industrial Bacteria, Aberdeen, Scotland. Cultures were maintained in the laboratory by routine sub-culturing onto fresh agar slopes approximately once per week. The cultures were maintained in the laboratory at a temperature of 25· C.
