The purpose of the present research is to find seeds of developing a nontraditional bioprocessing utilizing microbiogenic functions. As the first step for the purpose, general characteristics of microbial corrosion in the seawater were examined by employing the corrosion test for various metals, and based on the results a few bioprocessings were attempted. Results obtained are as follows :1.Microbial Corrosion of Copper Sheets and Its Application to Bioprocessing(1)Microbiological effescts on the corrosion of oxygen-free high-purity copper sheets were clarified by the SEM observation adn the EPMA analysis.(2)A mehod to produce concave details on a pecimen surface with the action of anaerobic bacterium, referred to as biomaching (MBM), was proposed by making artificially the anaerobic environment, and was shown to be valid.(3)The optimum temperature for MBM was found, and methods for improving the machining rate were devised.(4)The MBD process to make a metal crystal deposit and grow on the substrate, which was bioprocessed in advance, was developed, and its validity was confirmed by making copper crystals.2.Microbial Corrosion of Mild Steel Sheets and Its Application to Biomachining(1)The MBM process was successful in producing concave details on a pecimen surface.(2)The influencing factors on the MBM machining rate were clarified, and the condition for improving the machining rate were presented.3.Microbial Corrosion of Molybdenum SheetsFrom the microbial corrosion test of molybdenum sheets, it was found that diatoms (Achnanthes) corroded preferentially this material.

本研究的目的是寻找利用微生物功能开发非传统生物加工的种子。作为第一步的目的，在海水中的微生物腐蚀的一般特性进行了检查，通过使用各种金属的腐蚀试验，并根据结果的一些生物处理的尝试。1.铜片的微生物腐蚀及其在生物处理中的应用（1）通过SEM观察和EPMA分析，阐明了微生物对无氧铜腐蚀的影响。(2)A本文提出了一种通过人工制造厌氧环境，利用厌氧细菌的作用，在试样表面产生凹陷细节的方法--生物刻蚀（MBM），并证明了该方法的有效性。（3）找到了最佳的MBM加工温度，并设计了提高加工速度的方法。（4）开发了在预生物处理的基体上制备金属晶体存款和生长的MBD工艺，并通过制备铜晶体证实了其有效性。2.低碳钢板的微生物腐蚀及其在生物加工中的应用（1）MBM工艺成功地在试样表面上制备了凹状细节。（2）阐明了影响MBM加工速度的因素，提出了提高MBM加工速度的条件。3.钼板的微生物腐蚀通过对钼板的微生物腐蚀试验，发现硅藻（曲壳藻）优先腐蚀钼板。
