Genome scale metabolic modelling of Phaeodactylum tricornutum
… of genome scale metabolic models (GSMs) of Phaeodactylum tricornutum, a model diatom, the characterisation of physiological properties and the identification of the potential strategies to optimise the lipid production. GSMs were constructed based on a previously published model and …

Expanding the molecular tools for the microalgae Chlorella vulgaris and Phaeodactylum tricornutum
… alga *Chlorella vulgaris* and the marine diatom *Phaeodactylum tricornutum*, both exhibit rapid growth rates and high density cultures making them prominent candidates for use in numerous applications. Work in this thesis was sponsored by the algal biotechnology company Algenuity, Stewartby, …

Molecular biology of B vitamin metabolism genes and their regulation in Phaeodactylum tricornutum
… 3’-RACE showed that the THIC and SSSP genes in Phaeodactylum tricornutum did not respond to thiamine supplementation at the transcriptional or post-transcriptional level, even though thiamine is taken up by the cells. Furthermore, unlike in the green alga Chlamydomonas reinhardtii, which has …

Vitamin B12-mediated physiology, mutualisms, and gene regulation studies in Chlamydomonas reinhardtii and Phaeodactylum tricornutum
… reinhardtii, and the marine diatom, Phaeodactylum tricornutum, also have a B12-independent form of methionine synthase (METE). This means that they can utilize METH if B12 is available, but when it is absent or in limited supply, they use METE. To study the influence of vitamin …

Mixotrophic Production of Omega-3 Fatty Acid-rich Alga Phaeodactylum tricornutum on Biodiesel-derived Crude Glycerol
… used in the mixotrophic production of the alga, Phaeodactylum tricornutum, which is an eicosapentaenoic acid (EPA) producing diatom. Mixotrophic growth is when cells perform autotrophic and heterotrophic modes of growth concurrently. EPA is an omega-3 polyunsaturated fatty acid that has been …

Characteristics of Nitrogen- and Iron-Limited Growth in the Diatom Phaeodactylum tricornutum, and in Natural Phytoplankton Populations.
… environment (using the coastal marine diatom Phaeodactylum tricomutum), and in the open ocean (e.g. Jellicoe Channel and the Subtropical Convergence Zone, New Zealand). Although the characteristics of ammonium uptake have been extensively studied in marine phytoplankton, comparatively little …

Investigating mechanisms of triacylglycerol synthesis induced by nitrogen depletion in the diatom Phaeodactylum tricornutum and characterising its diacylglycerol acyltransferases and phospholipid: diacylglycerol acyl transferase
The ability of the diatom Phaeodactylum tricornutum (P. tricornutum) to accumulate triacylglycerol (TAG) and synthesise the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic (DHA) has led to interest in their development for biofuels and human nutrition. Nitrogen depletion is a …

Development of a hydrogel-based biocompatible platform for studying metabolic interactions between algae and bacteria
… bacteria co-cultured with their algal host Phaeodactylum tricornutum, which is shaped by diffusion process using the hydrogel-based platform.

The Effects of Temperature on the Growth and Competition of Phytoplankton
… I focused on mixed populations of the diatoms Phaeodactylum tricornutum and Thalassiosira pseudonana and how they compete across stable and fluctuating temperatures under high and low nitrate concentrations. I could show that under stable thermal conditions, the outcome of competition could be …

Bioinstrumentation and Statistical Methods for Investigating Host-Microbial Interactions
… metabolite exchange. Using a model host alga Phaeodactylum tricornutum, I describe bacterial responses to algal metabolites in the porous microplate. I extend the findings to provide an insight into how different bacterial species partition host nutrients. The host-microbiota relationship …

Growth, photophysiology and photosynthesis of two marine diatoms grown under predictable intra-diel light fluctuations
… in the diatoms Thalassiosira pseudonana and Phaeodactylum tricornutum when grown under square-wave (SQ), sinusoidal (SI), and low (LF) and high (HF) amplitude light fluctuations of a 1-hour period each with the same light dose. Acclimation to increasing light fluctuation amplitude was found …

Utilising microalgal mixotrophy to maximise larval nutrition
… three microalgal species: Tetraselmis suecica, Phaeodactylum tricornutum and Cyclotella cryptica were screened for mixotrophic or heterotrophic growth with glucose, glycerol or acetate. These strains had a shift in the fatty acid profile in favour of shorter chain, saturated fatty acids and an …

The biogeochemistry of lipid derived infochemical signals in the ocean
… grazer Oxyrrhis marina and both wild type Phaeodactylum tricornutum and a chronically stressed, transgenic strain (PtNOA). Grazing was suppressed in the PtNOA treatments compared to the WT, likely due to upregulation of small unknown lipophilic molecules. This suggests that cellular stress …
