<p> We evaluated biological activities in terrestrial extreme environment samples from Antarctica soils and submarine hydrothermal systems by measuring phosphatase activities. The soil of Site 8 (near a penguin rookery) showed almost the same level of phosphatase activities as usual surface soil sampled in Yokohama National University (YNU ) campus, while the soil of the other stations showed much less activities. Massive sulfide chimneys of submarine hydrothermal vents in South Mariana Backarc also showed phosphatase activities: The exterior part of the chimnies showed higher than the interior part, suggesting the prokarotic habitat and cell density. Alkaline phosphatase (ALP) in the extracts from the soil of Antarctica Site 8 and chimney samples was characterized by the laboratory-based enzymatic assessments. Among these profiles, firstly, the Antarctica ALP showed the maximal at 37℃, the chimney ALP showed the maximal at 90℃, while ALP from the YNU soil showed the maximal at 60℃. Secondly, the gel filtration chromatography showed that the ALP activity in both Antarctica and chimney samples was found mainly in the fraction whose molecular weights were around 100000 Dalton. The ALP activity was diminished with EDTA and was recovered with addition of zinc ion. The present results showed that zinc-containing metalloenzymes are present in the Antarctica soils and the chimneys in the hydrothermal system, and that phosphatases are useful bio-signatures for extant life in extreme environments. Phosphatase activity could be used for life detection in extraterrestrial environments, as well as for evaluation of biochemical function of prebiotic samples.</p>

EFFECTS OF MINERALS FOR EVOLUTION OF ORGANIC MATTER IN THE SOLAR SYSTEM

<p>Extraterrestrial organic matter provided by meteorites and interplanetary dust particles could have been contributed to the origin of life on the Earth. As a part of chemical evolution toward life, it is important to understand origin and evolution of organic matter in the Solar System and beyond. Formation and evolution of organic matter in the Solar System have been studied over decades. Although organic matter usually exists with minerals as in meteorites, effects of minerals for the processes of extraterrestrial organic matter are not well understood. Here I review the relationships between organic matter and minerals observed in meteorites, experimental studies of interactions of organic matter with minerals, and mechanisms of effects of minerals for organic reactions.</p><p>Extraterrestrial organic matter provided by meteorites and interplanetary dust particles could have been contributed to the origin of life on the Earth.

<p>Roles of solar energetic particles in habitability of the early Earth and in formation of amino acids and their enantiomeric excesses were examined by simulation experiments. SEPs are mainly composed of high energy protons, and it was suggested that high-flux SEPs were generated from the young Sun and entered into Earth atmosphere. It was shown that such SEPs were major energy to form amino acid precursors, in the case that primitive Earth atmosphere was slightly reducing. SEPs were produced N<sub>2</sub>O, which is greenhouse effect gas and could be keep the early Earth habitable. SEPs could generate spin-polarized muons, which may have formed enantiomeric excesses of amino acids.</p>

<p>Pyrolysis gas chromatography-mass spectrometry (GC / MS) can reveal more detailed characteristics of the structure of organic matter by changing the pyrolysis temperature. In order to investigate the structure and thermal characteristics of complex organic matter, a method "Continuous" that performs GC / MS analysis at a series of pyrolysis temperatures by repeatedly using the same sample, and a method that prepares a new sample for each pyrolysis temperature "Replaced" step heating methods were examined and evaluated. In addition, Fourier transform infrared spectroscopy (FT-IR) analysis was also performed using a heating stage to observe changes in the sample during analysis.The reproducibility of each of the two methods was confirmed. With the "Replaced" method, it was possible to discriminate fine peaks, and with "Continuous", the difference in the detected compounds was remarkable for each pyrolysis temperature. The results of the experiments using FT-IR were in line with the tendency of the compound species detected at each pyrolysis temperature in the GC / MS experiments. Therefore, it was found that performing pyrolysis GC / MS analysis by changing the pyrolysis temperature using both methods is useful for the analysis of the components and thermal properties of complex organic molecules.</p>
