The discovery is a contribution to understanding the ecosystem service and mechanism in improving water quality. This is helpful to develop innovative ecobiotechnology to treat polluted water. New insight into natural mechanisms of ecological biotechnology that remediate aquatic ecosystems and improves water quality.

The detergent Lanza-Automat inhibited water filtration by the bivalve (oysters) Crassostrea gigas. As a result, the removal from water of suspended cells of Saccharomyces cerevisiae was inhibited by the detergent. New data are in line with the previous findings of the same author on the similar action of other detergents as well as surfactants (e.g., Ostroumov, 2000, 2001). The author formulated and substantiated a new conceptualization of ecological hazards from chemicals that pollute aquatic environment. The author proposed that the ability of bivalves to contribute to water purification and ecosystem remediation may be damaged by chemical pollutants exemplified by detergents. The concept is in accord with the conclusions made on some other studies of the same author using bivalves Unio tumidus (DAN, 1991, v.380: 714-717); Mytilus edulis (DAN, 1998, v.262: 574-576) and Crassostrea gigas (DAN, 2001, v. 378: 283-285). Experiments were performed using mollusks (oysters), Crassostrea gigas Thunberg, and a cell suspension of Saccharomyces cerevisiae. The cell suspension was a model of suspended matter in aquatic ecosystem. Laundry detergent Lanza-Automat inhibited water filtration by oysters C. gigas. As a result, the removal of the cells (S. cerevisiae) from water was inhibited. This demonstrated a new type of ecological hazard caused by water pollution with chemical pollutants at sublethal concentrations. This hazard is associated with the fact that chemical pollution of water causes inhibition of the physiological activity of filter-feeders, thereby inhibiting the important ecological processes of water filtration. These ecological processes contribute significantly to improving water quality, water purification and the related remediation of aquatic ecosystems (their ecological repair). [Effects on elimination efficiency (EEE); new concept of ecological remediation as ecological repair; new data on inhibitory effects of the detergent Lanza-Automat 20 mg/L on water filtration by oysters C. gigas and removal of the cells of S. cerevisiae from water (Tabl. 1); a summary table of effects of cationic, anionic, non-ionic surfactants, pesticides, potassium bichromate, on marine and freshwater bivalves, larvae of Ephemeroptera, rotifers, and Cladocera – mainly the data of the author plus some data from literature (Tabl. 2) The author identified "a new type of ecological hazard caused by water pollution. This hazard is associated with the fact that chemical pollution of water causes inhibition of the physiological activity of hydrobionts, thereby inhibiting the ecological processes mediated by the hydrobionts. These processes contribute significantly to water purification and the related remediation of aquatic ecosystems (their ecological repair)" (p.379)].
