From the Ocean to the Lab—Assessing Iron Limitation in Cyanobacteria: An Interface Paper
Hunnestad, Annie Vera; Vogel, Anne Ilse Maria; Digernes, Maria Guadalupe; Armstrong, Evelyn; Ardelan, Murat Van; Hohmann-Marriott, Martin Frank (Peer reviewed; Journal article, 2020)Iron is an essential, yet scarce, nutrient in marine environments. Phytoplankton, and especially cyanobacteria, have developed a wide range of mechanisms to acquire iron and maintain their iron-rich photosynthetic machinery. ... -
IRON AS A DRIVING FORCE OF LIFE: INVESTIGATING EFFECTS OF IRON SOURCE ON PHYSIOLOGICAL FACTORS AND BIOTIC IRON RELATIONSHIPS IN SYNECHOCOCCUS SP. PCC 7002
Hunnestad, Annie Vera (Doctoral theses at NTNU;2021:347, Doctoral thesis, 2021)Iron is one of the most abundant elements in the Earth’s crust, and yet it is a limiting factor for primary production in large parts of the world’s oceans. This is due to the low solubility of iron throughout the water ... -
Iron Speciation and Physiological Analysis Indicate that Synechococcus sp. PCC 7002 Reduces Amorphous and Crystalline Iron Forms in Synthetic Seawater Medium
Hunnestad, Annie Vera; Vogel, Anne Ilse Maria; Digernes, Maria Guadalupe; Ardelan, Murat Van; Hohmann-Marriott, Martin Frank (Peer reviewed; Journal article, 2020)Cyanobacteria have high iron requirements due to iron-rich photosynthetic machineries. Despite the high concentrations of iron in the Earth’s crust, iron is limiting in many marine environments due to iron’s low solubility. ... -
The Effects of Macronutrient Enrichments (ammonium) on the Distribution of Four Bioactive Trace Metals (Cd, Mo, Ni, Cu) in Seawater and Planktonic Biomass.
Hunnestad, Annie Vera (Master thesis, 2012)Environmental impacts of aquaculture can be widespread and serious, and one of the problems connected to this activity is the release of waste in the form of macronutrients. One important aspect is the potential of a shift ...
