In 1998–1999, Harvard researchers published their DNA identifications of samples of whale meat they obtained in the Japanese market, and found that mingled among the presumably legal (i.e. minke whale meat) was a sizeable proportion of dolphin and porpoise meats, and instances of endangered species such as fin whale and humpback whale.

Sewage treatment plants mix these organisms as activated sludge or circulate water past organisms living on trickling filters or rotating biological contactors. [ 5 ] Aquatic vegetation may provide similar surface habitat for purifying bacteria, protozoa, and rotifers in a pond or marsh setting; although water circulation is often less effective.
