The precipitation of carbonate in the ocean is the important problem concerning the cycle of carbon in nature. In the authors laboratory, studies have been made to clarify the specific properties of marine microorganisms from various viewpoints of microbiology. The crystal-forming bacteria show higher rates of detection in various marine microorganisms isolated from different sea areas. The authors studied the types of crystals deposited in the peptone medium prepared with natural sea water or artificial sea water, and obtained the following results by an analysis of X-ray diffraction. 1) Crystals deposited in medium prepared with natural sea water or Lyman and Flemings artificial sea water were calcium carbonate monohydrate. 2) The crystals deposited in the medium prepared with Herbsts artificial sea water were identified as magnesium ammonium phosphate hexahydrate.
