In this issue, latest knowledge on "Geochemistry of organic matter, microbes, and ecosystem" was compiled in ten review articles as a special volume of the Annual Meeting of the Geochemical Society of Japan, held at Hiroshima in September 2009. The key point of these studies is "molecular" and/or "elemental" scale techniques dealing with mainly organic and/or inorganic compounds including their isotopic compositions to elucidate roles of microbes in evolution and biogeochemical cycles. Though molecular analyses and cultivation experiments demonstrate a high diversity of microbial life, the relative abundances and ecological roles of archaea, bacteria, eukarya, and viruses have been largely unknown. We wish that this issue would act as useful media for the community and the new comers to this research field.
