The authors thank to Prof. J. Ishibashi, chief scientist of the Shinryu-Maru cruise and the other scientists, ROV operating team and crew of the cruise. Also, We are grateful to Mr. T. Kaneko, Yokohama National University, for providing technical advice and discussion. This research was funded by the Ministry of Education, Culture, Sports, Science and Technology of Japan through the Special Coordination Fund of the Archaean Park project; an international research project on interaction between the sub-vent biosphere and the geo-environment.

N2 - Pure seawater samples, at a temperature of 300°C (purity >97%) were collected from deep-sea hydrothermal vents at Suiyo Seamount, Izu-Bonin Arc, Pacific Ocean as a part of the Archaean Park Project. Dissolved and total hydrolyzable amino acids were determined by ion-exchange HPLC, and for the first time, their enantiomeric ratios were measured by reversed-phase HPLC. Glycine and serine were the two most abundant amino acids, followed by other proteinaceous amino acids such as alanine, glutamic acid and aspartic acid. Non-proteinaceous amino acids, e.g. β-alanine and γ-aminobutyric acid, were as minor constituents. The majority of the amino acids detected were of the L-form which suggests most of the amino acids detected were formed biologically and that there are active microbial communities near these hydrothermal systems.
