The Role of Microbial Diversity in the Cycling of Elements. (Summary of Workshop)

Abstract

Prokaryotes are the oldest and most diverse group of organisms, encompassing a wide array of adaptations to extreme environmental conditions. The prokaryotes, including both Archaea and Eubacteria, comprise a large and versatile gene pool which can be translated to include highly versatile physiological responses to the environment, resulting in ability to grow within an extraordinarily-wide spectrum of environmental conditions. The communal metabolism of microorganisms is largely responsible for global cycling of elements, resulting in evolution of the Earth’s biosphere throughout the living history of the Earth and in maintaining dynamic stability of the present biosphere. Microbial activities are also closely associated with present global climatic changes, both accelerating and slowing these processes.

In the discussions which follow (chapters 19 and 20), it is important to note that the remarks (questions and comments) were not prepared in written form by those participants, but represent summaries of the informal workshop discussion.
