| Research Abstract |
Microbial mat and film on hot-spring travertines were studied for understanding developmental processes of stromatolites that had been widely debeloped in ancient oceans. Togetherwith a post-doc reseacher, I performed continuous observation of sedimentary texture and water chemistry. Genetic analyses were also done for the specimens collected from the travertine surfaces. The results of these analyses indicated that the laminated textures were basically daily and refrected from metabolic cycle of photosynthesic bacteria including cyanobacteria. Results from study localities (e.g., Nagayu hot-sprng in Ohita Prefecture and Myoken hot-spring in Kagoshima Prefecture) were published in reseach papers including three international journal papers. Study in Nagayu hot-spring was especially important in terms with similality with the ancient stromatolites.
