Water Biomachinery:   Innovative conceptualization. A step to a silent revolution in ecology, environmental science, and water science. Ecosystem function and water safety.

http://5bio5.blogspot.com/2012/07/innovative-conceptualization-of.html

This blog post will be many times updated, with addition of new important references.
The author suggested an innovative conceptualization of ecosystem: biomachinery. Biomachinery is a new scientific term that was proposed by the author, Dr. S.A.Ostroumov (Moscow State University; Fulbright Award winner). It means ecological mechanisms that include biological communities and biodiversity; biomachinery's function is improving water quality. 

The innovative experimental data analysis, concepts, and generalizations in this article provide the fundamental elements of the new qualitative theory of biocontrol of water quality in a systematized form. The theory covers water self-purification in freshwater and marine ecosystems. The theory is supported by the results of the author’s experimental studies of the effects exerted by some chemical pollutants. These chemical pollutants included synthetic surfactants, detergents, and other xenobiotics. The author studied their effects on aquatic organisms.

Example: a paper published in 2010. The new fundamental conceptualization provides a basis for remediation of polluted aquatic ecosystems including purification of water in lakes, reservoirs, and rivers. This paper presents the qualitative theory of the water self-purification mechanism of aquatic ecosystems. This theory will be useful to develop phytoremediation and other types of green technologies.

Additional info on how the concept of biomachinery was developing, step by step, in a series of publications - a list of these publications (some of them with annotations) see  below at the end of this blog post.

A comment about the series of publications:


During the period 1998 – 2012 a series of papers on aquatic ecosystems, water quality and hazard assessment were published by the author. The size of the papers was limited. The author got more facts in support of the conclusions of those papers. A broad range of facts which supported the points and conclusions of those papers was presented in a book that was published by the author, a Fulbright Award winner. The title of the book:  Biological Effects of Surfactants. A full reference is given below.

The innovations in the papers and the book were the conclusions on a bigger role (than it was thought before) of aquatic organisms in safety and sustainability of water resources and water supply.

This conclusion leads to not only a fundamental change in the vision of ecology of freshwater and seas but also to a change in management of natural resources, water resources and bioresources. The conclusions of Dr. S.Ostroumov's papers mean that without healthy aquatic ecosystems and healthy state of aquatic organisms it is impossible to have safe water supply. It makes the protection of biodiversity and healthy state of aquatic organisms not only a humanistic goal but also a rigid prerequisite for having water of acceptable quality. This is a fundamental change in goals and practice of environmental and resource management of to-day and to-morrow.

This paper is the first publication that considered an aquatic ecosystem as an analog of a bioreactor, with some specific features that were described in the paper.
This paper gave a revolutionary new insight into the core functions and identity of ecosystem as a bioreactor to maintain water quality;

**
This paper was the first that discovered the multi-faceted role of the entire broad range of aquatic organisms of all main groups of biodiversity in water self-purification. The conclusion was made that the complex of all the organisms, the entire biota is a unique (both changeable and fragile) part of the mechanism of ecosystem service to improve water quality;

**
It is the first paper that reported two new experimental results. First, the new author’s experiments measured the biota-driven fluxes of the matter and chemical elements in a model ecosystem. Second, the authors got another innovative result: a discovery of effects of chemical pollutants. Namely, these biota-driven flows of the chemical elements were decreased by a chemical pollutant exemplified by a synthetic surfactant:

65628020163255/ Abstract: The effect of synthetic anionic surface active substance (SAS) sodium dodecylsulfate (SDS, 4 mg/l) on the kinetics of water filtration by mussel Mytilus edulis was studied. A suspension of algae Isochrysis galbana was added to the vessel with the mussels, and their filtration activity was measured by counting the concentration of the algae cells in the experimental vessels. Algae concentration was measured every 30 min for an hour and a half. The inhibiting effect on the mollusk filtration rate (FR) was qualitatively described.
After the first 30 min filtration at 4 mg/l initial SDS concentration, the cell density was 322% of the control. The inhibiting effect was observed later as well. Due to FR inhibition in the vessels with the above specified initial SDS concentration, the algae cell density was 6.4 and 14.7 times that of the control after 1 and 1.5 h, respectively. Thus, SAS SDS can decrease the natural capacity of aquatic ecosystems for self-purification and disturb other aspects of ecosystem functioning through inhibiting the filtration activity of mussels. The obtained data are discussed in the context of environment and hydrosphere protection from pollution.
