The intestinal tract of warm-blooded animals also contains viruses that can contaminate water and cause disease. The foreign bacteria rapidly reproduce and consume debris and nutrients in the sewage, but use up all the oxygen in the water in doing so. Aquatic Microbial Ecology From Wikipedia, the free encyclopedia Aquatic Microbial Ecology is a monthly peer-reviewed scientific journal covering all aspects of aquatic microbial dynamics, in particular viruses, prokaryotes, and eukaryotes in marine, limnetic, and brackish habitats. The Microbiology Society has a vision and mission around which we base our strategy. Many microorganisms are found naturally in fresh and saltwater. The algae that thrive in water is also an important food source for other forms of life. They penetrate host cells and use the nucleic acid of other cells to replicate. The plentiful numbers of these organisms in turn are used as food for other life. Therefore, these microorganisms are intimate members of the food web in at least two ways. Without this recycling , plants would have few, if any, organic nutrients to use for growth. "Water Microbiology Aquatic environments occupy more than 70% of the earth’s surface. Finally, Escherichia coli can be detected easily and inexpensively. But, salt loving (halophilic) bacteria abound near the surface, and some bacteria that also live in freshwater are plentiful (i.e., Pseudomonas and Vibrio ). He is an environmental microbiologist specializing in the Another microorganism found in saltwater are a type of algae known as dinoflagellelates. One popular test measures the turbidity of the water. These can be important in the food chain that forms the basis of life in the water. Contamination of drinking water with a type of Escherichia coli known as O157:H7 can be fatal. Microbes can also be physically excluded from the water by passing the water through a filter.
