amp Anaerobic Bacteria Introduction Bacteria can exist in a wide variety of environments including environments that lack oxygen In fact oxygen is toxic to some bacteria This toxicity is usually due to the accidental formation .

Anaerobic Bacteria. Anaerobic bacteria or anaerobes are bacteria that do not need oxygen to live. In humans, these bacteria generally live in the gastrointestinal tract, but they may also be found in other places outside the body, including in the soil and water, in foods, and in animals. Some anaerobes are beneficial to humans, but others can cause illnesses. Characteristics of an anaerobic bacterial infection are bad-smelling pus, the formation of abscesses, and the destruction of tissue.. Loynachan. Citation: Thomas . Loynachan. . 2008. Soil bacteria.. Publication Date : June 2008. Introduction. . Bacteria are the most numerous of the culturable soil microorganisms. Their numbers are often as high as 1 x 10. Binary fission. Prokaryote cells grow by increasing in cell number (as opposed to increasing in size).. Replication is by binary fission, the splitting of one cell into two. Therefore, bacterial populations increase by a factor of two (double) every generation time.
