Invention of Artificial Rice Field Soil: A Tool to Study the Effect of Soil Components on the Activity and Community of Microorganisms Involved in Anaerobic Organic Matter Decomposition.

ABSTRACT: Soils are characterized by diverse biotic and abiotic constituents, and this complexity hinders studies on the effects of individual soil components on microorganisms in soil. Although artificial soils have been used to overcome this issue, anoxic soils have not yet been examined. We herein aimed to create artificial soil that reproduces anaerobic methane production by soil from a rice field. Organic materials and mineral particles separated from rice field soil were mixed to prepare an artificial soil matrix; the matrix was added with a small volume of a soil suspension as a microbial inoculum. When the microbial inoculum was added immediately after matrix preparation, anaerobic decomposition was markedly less than that by original soil. When the inoculum was added 9-15 days after soil ma
