Application

类似于纯 HAp 纳米粉体（目录号 677418），可将硅取代的羟基磷灰石 (Si-HAp) 纳米粉体结合到可生物降解的聚合物复合材料中或沉积在生物相容性表面上。据发现，硅离子代入一部分 HAp 晶格的磷酸化位点可增强 HAp 的生物活性。[1][2]

Discovery of piperonal-converting oxidase involved in the metabolism of a botanical aromatic aldehyde.

Shiori Doi et al.

Scientific reports, 6, 38021-38021 (2016-12-03)

Piperonal-catabolizing microorganisms were isolated from soil, the one (strain CT39-3) exhibiting the highest activity being identified as Burkholderia sp. The piperonal-converting enzyme involved in the initial step of piperonal metabolism was purified from strain CT39-3. Gene cloning of the enzyme
