Investigating mechanisms of triacylglycerol synthesis induced by nitrogen depletion in the diatom Phaeodactylum tricornutum and characterising its diacylglycerol acyltransferases and phospholipid: diacylglycerol acyl transferase
… development for biofuels and human nutrition. Nitrogen depletion is a well-studied experimental system for producing high levels of TAG in P. tricornutum. Identication of the mechanisms involved in TAG synthesis holds promise for increasing TAG yields. Numerous studies of nitrogen depletion …

The role of glycogen Metabolism in the Adaptation to environmental Changes of the cyanobacterium Synechocystis sp. PCC 6803
… towards glycogen synthesis, such as high light, nitrogen depletion (chlorosis). This work expands our understanding of how to regulate carbon flow towards desired compounds by diverting it from glycogen reserves. The research also focuses on the importance of glycogen in the transition from …

Lipid Production by Microalgae Treating Municipal Wastewater
… ameliorated through laboratory manipulations of nitrogen availability and light intensity. This two-part project measured microalgae lipid levels in open raceway ponds located at the San Luis Obispo Water Reclamation Facility (SLO WRF) grown in primary clarifier effluent and then performed …

Primary production of particulate protein amino acids : algal protein metabolism and its relationship to the composition of particulate organic matter
… with conversion of inorganic carbon and nitrogen into protein, the effects of NH+4 limitation on free amino acid and protein composition and incorporation of inorganic 14C were studied in the marine chlorophyte, Nannochloris sp. (clone GSB Nanna). Free amino acid metabolism was sensitive …

From the ice to the open ocean : threats to phytoplankton productivity in the Antarctic marine ecosystem from a changing climate
… of phytoplankton under nutrient limitation. Nitrogen depletion in F. cylindrus had a strong influence on non-photochemical quenching capacity and resulted in the impairment of photosynthetic electron transport resulting in the formation of Qʙ non-reducing PSII centres within the photosystem …

Physiological studies of phototrophy and heterotrophy in two algae with contrasting nutritional characteristics, Pyrenomonas salina (Cryptophyceae) and Poterioochromonas malhamensis (Chrysophyceae)
… first hypothesis was that P. salina responds to nitrogen deprivation by mobilizing phycoerythrin in order to help sustain cellular nitrogen requirements. In response to nitrogen depletion from the culture medium, the phycoerythrin content of P. salina cells decreased prior to any changes in …
