自上个世纪开始,已知细菌,包括蓝藻,参与CaCO 3的细胞外形成和沉淀。还已知一些海洋细菌在含Ca的人工介质中形成方解石颗粒。然而,尚未对这些颗粒进行详细分析。本研究的目的是分离的海洋细菌,形成碳酸钙颗粒在培养基中,以分析颗粒的结构详细。01 OK 105-5-5是从日本冲绳安那珊瑚礁中的海鞘中分离到的一株α变形菌纲的细菌。在含钙的人工培养基中产生胞外CaCO 3颗粒。X射线衍射分析,红外光谱,电感耦合等离子体原子发射光谱法表明,细胞外颗粒含有富含镁的方解石样晶体多晶型物。这种碳酸钙的晶体形式与许多海洋无脊椎动物骨骼中发现的富含镁的方解石相似。这种细菌提供了一个很有前途的工具,研究机制参与形成的富镁生物方解石。
Since the beginning of the last century, bacteria, including cyanobacteria, have been known to be involved in the extracellular formation and precipitation of CaCO3. It is also known that some marine bacteria form calcite granules in Ca-containing artificial media. However, a detailed analysis of these granules has not yet been performed. The objective of the present study was to isolate marine bacteria that form CaCO3granules in a culture medium to analyze the structure of the granules in detail.Pseudovibriosp. 01OK 105-5-5, belonging to the class Alphaproteobacteria, was isolated from an ascidian in a coral reef at On-na, Okinawa, Japan. It produced extracellular granules of CaCO3in a Ca-containing artificial medium. X-ray diffraction analysis, infrared spectroscopy, and inductively coupled plasma atomic emission spectrometry demonstrated that the extracellular granules contained Mg-rich calcite-like crystal polymorphs. This crystal form of CaCO3was similar to that of Mg-rich calcite found in the skeletons of many marine invertebrates. This bacterium provides a promising tool for studying the mechanisms involved in the formation of Mg-rich biogenic calcite.
