[Abstract] Diatoms are an ecologically important group of eukaryotic microalgae with properties that make them attractive for biotechnological applications such as biofuels, foods, cosmetics and pharmaceuticals. Phaeodactylum tricornutum is a model diatom with defined culture conditions, but routine genetic manipulations are hindered by a lack of ...

[Abstract] The marine beta-glucan laminarin is an abundant storage polysaccharide in microalgae. High production rates and rapid digestion by heterotrophic bacteria turn laminarin into an ideal carbon and energy source, and it is therefore a key player in the marine carbon cycle. As a main storage glucan laminarin also plays a central role in the energy ...

[Abstract] Genome editing in diatoms has recently been established for the model species Phaeodactylum tricornutum and Thalassiosira pseudonana. The present protocol, although developed for T. pseudonana, can be modified to edit any diatom genome as we utilize the flexible, modular Golden Gate cloning system. The main steps include ...

[Abstract] The establishment of the CRISPR/Cas9 technology in diatoms (Hopes et al., 2016; Nymark et al., 2016) enables a simple, inexpensive and effective way of introducing targeted alterations in the genomic DNA of this highly important group of eukaryotic phytoplankton. Diatoms are of interest as model microorganisms in a variety of ...

[Abstract] This protocol describes a method to extract ribulose-1,5-bisphosphate carboxylase oxygenase (Rubisco) from diatoms (Bacillariophyta) to determine catalytic performance. This protocol has been adapted from use in cyanobacteria and higher plants (Andrews, 1988; Whitney and Sharwood, 2007). First part (steps A1-A3) of the extraction provides ...
