Structure of microbial community in soil ecosystem: detection of environmental filters

MURAKAMI, M. (Chiba Univ.)

Microorganisms have very limited abilities to move and the occurrence of a function of microorganisms within soils thus is largely determined by the occurrence of mechanisms that bring microorganisms into contact with the environments, which should determine the dominated functioning within the soils. This paradigm is known as the “sleeping beauty paradox". This idea was tested in field and laboratory experiments. In the field experiment, the effect of earthworms on the assemblage of soil microorganisms was assessed. In the microcosm experiment, five different microcosms with microorganisms were established. The changes in assemblage structure of microbes was assessed by T-RFLP and Cloning-Sequence analyses.
