1.1 This test method specifies the operational parameters required to grow a repeatable Pseudomonas aeruginosa biofilm under high shear (1). The resulting biofilm is representative of generalized situations where biofilm exists under high shear rather than representative of one particular environment.

1.2 This test method uses the Centers for Disease Control and Prevention (CDC) biofilm reactor. The CDC biofilm reactor is a continuously stirred flow reactor with high wall shear. Although it was originally designed to model a potable water system for the evaluation of Legionella pneumophila (2), the reactor is versatile and may also be used for growing and/or characterizing biofilm of varying species (3 and 4).

1.3 This test method describes how to sample and analyze biofilm for viable cells. Biofilm population density is recorded as log colony forming units per surface area.

1.4 Basic microbiology training is required to perform this test method.

1.5 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.

1.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
