Research Abstract

Project study of Mineral - Microbe interaction was carried out for 3 years. This project study aimed to disclose insights of new earth image and to have some new insights of mineral image ; bio-related minerals and bio-related surface solid earth. A mineral - microbe interaction was concretely demonstrated. (1) Arsenic contamination of ground water in Bangladesh was studied : dissolution of arsenic was demonstrated by experiments using microbial culture experiments. There are two disputive hypotheses of reductive dissolution and oxidative dissolution, but the experimental results showed that reductive dissolution was true and under oxidatrve conditions no arsenic dissolved. Microbe which is related to the dissolution was examined by gene analysis and fatty acid analysis. Such microbes are playing an important role in dissolution of arsenic from sediments. These results are summarized in research papers (including a paper in print). (2) Microhial weathering of biotite In natural sample and in experiments, microbial weathering of biotite was disclosed : in the case, three types of microbes are acting in the weathering process. Examining bacterial Influences on changes in weathering of uranium minerals from Tohno, secondary uranium minerals, cherni kovitc and metaankolcitc were found to be formed. (3) Examining iron ore deposit bio-role was disclosed. Stromatolite structure was also examined. Iron oxides from Gunma iron mine and arsenic contaminated materials were disclosed to be not purely iron hydroxide but hydroxides with phosp horous component and sulphate component. (4) Magnetotactic bacteria such as Magnetospirillum magnetotacticum were examined : elongation directions of magnetite with tear drop type were an alyzed. (5) We discovered peculiar structure of icosahedral domains of framboidal pyrite from sediment samples from Niigata Pref.
