摘 要: 实验室培养的硅藻多存在尺寸和结构退化现象,难以获取大尺寸且结构均一的壳体。选用3种典型硅藻进行不同方法培养,以49 d为培养周期观察其生长状况,发现自然水域条件和微生物共存环境能有效抑制藻种退化,使硅藻恢复天然尺寸,尤其是批量培养平台可实现硅藻优质,快速繁殖,可获取尺寸大而均一且优质的硅藻壳体,这类壳体用于微纳米制造和功能微器件研究优于一般实验室培养的壳体。
关 键 词: 微生物学;硅藻培养;生长退化;微纳米结构;硅质壳

Abstract: It is difficult to obtain diatom frustules with bigger and uniform size in laboratory culture environment, because growth degradation of diatom is hard to avoid. In this paper, three types of diatoms were cultured in different environments and observed in the following 49 days. The experimental results indicate that natural water and microorganism environment successfully prevent diatoms from growth degrading and make diatoms recover to original size. The batch culture system in this study can be used to obtain bigger and uniform frustules, which is more functional when used in micro-nanofabrication and functional micro-device study.
Key words: microtiology; diatom culture; growth degradation; micro-nanostructure; frustle
