Small heterotrophic bacteria of the genus Rhizobium capable of forming symbiotic noduies on the roots of leguminous plants. In the nodules the bacteria fix atmospheric nitrogen that is used by the plants.
Some contain compounds which kill useful bacteria and encourage algae growth when they are in wastewater that reaches receiving waters. Disinfectant A chemical or physical process that kills pathogenic organisms in water.
Some reasons for adding chlorine are reducing the number of coliform bacteria (Most Probable Number), obtaining a particular chlorine residual, or oxidizing some substance in the water. In each case a definite dosage of chlorine will be necessary.
Phagocyte Any cell which engulfs and usually digests particles, microorganisms such as bacteria, or harmful cells. Phenols See Halogenated Biphenyls.

decomposition The breakdown of matter by bacteria and fungi. It changes the chemical makeup and physical appearance of materials. deep water That part of the ocean below the main thermocline.
Another type of root symbiotic association occurs between several species of trees and nitrogen fixing bacteria. In these associations, nodules are produced by the roots of the host plant upon bacterial infection.
Methane is released from methane producing bacteria (methanogens) that live in these anaerobic places. Methanogens in termite guts are the source of methane released by termites.
In the environment, the half-life is the time it takes for half the original amount of a substance to disappear when it is changed to another chemical by bacteria, fungi, sunlight, or other chemical processes.
