    • Flashing light emitting diodes (LEDs) induce proteins, polyunsaturated fatty acids and pigments in three microalgae 

      Lima, Serena; Schulze, Peter Simon Claus; Schüler, Lisa M.; Rautenberger, Ralf; Morales-Sanchez, Daniela; Santos, Tamára F.; Pereira, Hugo; Varela, João C.S.; Scargiali, Francesca; Wijffels, Rene Hubertus; Kiron, Viswanath (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-11-25)
      As the periodic emission of light pulses by light emitting diodes (LEDs) is known to stimulate growth or induce high value biocompounds in microalgae, this flashing light regime was tested on growth and biochemical composition of the microalgae <i>Nannochloropsis gaditana, Koliella antarctica</i> and <i>Tetraselmis chui</i>. At low flashing light frequencies (e.g., 5 and 50 Hz, Duty cycle = 0.05), ...

    • Flashing lights affect the photophysiology and expression of carotenoid and lipid synthesis genes in Nannochloropsis gaditana 

      Lima, Serena; Lokesh, Jep; Schulze, Peter S.C.; Wijffels, Rene Hubertus; Kiron, Viswanath; Scargiali, Francesca; Petters, Sebastian; Bernstein, Hans Christopher; Morales-Sanchez, Daniela (Journal article; Tidsskriftartikkel; Peer reviewed, 2022-11-20)
      Nannochloropsis gaditana is a promising microalga for biotechnology. One of the strategies to stimulate its full potential in metabolite production is exposure to flashing lights. Here, we report how N. gaditana adapts to different flashing light regimes (5, 50, and 500 Hz) by changing its cellular physiology and the relative expression of genes related to critical cellular functions. We analyzed ...

    • Growth strategies of Chlorella vulgaris in seawater for a high production of biomass and lipids suitable for biodiesel 

      Rautenberger, Ralf; Detain, Alexandre; Skjånes, Kari; Schulze, Peter Simon Claus; Kiron, Viswanath; Morales Sanchez, Daniela (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-12-09)
      Chlorella vulgaris is a freshwater microalga that synthesises large amounts of saturated lipids, which makes it suitable for production of bioenergy and biofuels. Since its cultivation usually requires freshwater, it competes with agriculture, economic development and ecological conservation for this limited natural resource. This study investigated the possibility of the partial replacement of ...

    • Temperature-dependent lipid accumulation in the polar marine microalga Chlamydomonas malina RCC2488 

      Morales-Sanchez, Daniela; Schulze, Peter Simon Claus; Kiron, Viswanath; Wijffels, Rene Hubertus (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-12-23)
      The exploration of cold-adapted microalgae offers a wide range of biotechnological applications that can be used for human, animal, and environmental benefits in colder climates. Previously, when the polar marine microalga <i>Chlamydomonas malina</i> RCC2488 was cultivated under both nitrogen replete and depleted conditions at 8°C, it accumulated lipids and carbohydrates (up to 32 and 49%, respectively), ...
