Kultivierung von Mikroalge: Lipidgewinnung, Evaluierung der antioxidativen Wirkung und Modellierung des Wachstums sowie der Lipidgewinnung [PDF]

open access: yes, 2013
Two strains of microalgae were studied with regards to biomass concentration, total lipid content and fatty acid content and composition. The strains were a freshwater and a marine microalga, Chlorococcum sp. and Nannochloropsis sp., respectively.

HIGHLY BRANCHED ISOPRENOID ALKENES FROM DIATOMS: A BlOSYNTHETIC AND LIFE CYCLE INVESTIGATION [PDF]

open access: yes, 2003
In addition to the production of phytol (from chlorophylls) and sterols, a limited number of diatom species are capable of synthesising unusual C25 and C30 highly branched isoprenoid (HBl) alkenes.

Valve Teratology of Two Marine Diatoms Under the Artificial Culture: Forms and Potential Mechanism [PDF]

open access: yes, 2014
硅藻的细胞壁由一层硅质组成,分为上下两个壳面,具有种间特异性的花纹,是硅藻分类学的重要依据。硅质壳的外形及花纹通常具有规则性的轮廓及排列方式。如果处于环境胁迫下,硅藻硅质壳的轮廓和花纹就可能发生改变,称之为硅藻的形态畸变。这些畸变有时很轻微,畸变增加了形态分类学的难度。一般的畸变形式表现在壳面的整体轮廓改变,也可能发生在壳面的孔纹、壳缝及各种附属结构上。导致硅质壳畸变的原因有多种,其中长期的人工培养可以造成高比例的硅藻畸变。 本文依托国家自然科学基金项目“海洋硅藻硅质壳变形的特征与生态学机制 ...
