| Research Abstract |
We analyzed the synthesis and accumulation of oxidative damage base in the cell in low temperature environment. After isolating deep sea bacteria each from the Boso ( 6,000m) and south mariana area ( 2,900m), and comparing resolution gene MutT of the oxidative damage base with the Escherichia coli origin gene, the specific activity of MutT showed a high value of approximately 2 times than Escherichia coli and the substrate specificity for the oxidation damage base was more remarkable than Escherichia coli and was high. Then, as a result of 8-OH-G quantity in microbe genomic DNA in the deep sea which collected sea water in MR09-04 (JAMSTEC) to check 8-OH-G production, there were more deep sea microbes approximately 10 times than an microbe from surface sea water.
