Cochrane Database Syst Rev ; 3: The organism has secreted enzymes that breakdown substances into smaller organic molecules which are then absorbed into the cells of the microbes and used for cellular respiration. Biofilms may move collectively, by rippling or rolling across the surface, or by detaching in clumps.

The UV exposure breaks down the bonds in the non-ionic, organic compounds oxidation which creates carbon dioxide and water. Research work on PHA could be rapidly initiated with these ready-to-use techniques and microbial strains.

Microbial contamination regulations vary substantially by the use of the water that is being analyzed, for example, wastewater and pharmaceutical water have very different requirements for eliminating microbial contamination.

The position can be structurally compared to some indirect form of consequentialism and may attract parallel critiques see Henry Sidgwick on utilitarianism and esoteric morality, and Bernard Williams on indirect utilitarianism.
