    • Associated bacteria of Botryococcus braunii (Chlorophyta) 

      Gouveia, Joao Diogo; Lian, Jie; Steinert, Georg; Smidt, Hauke; Sipkema, Detmer; Wijffels, Rene Hubertus; Barbosa, Maria (Peer reviewed; Journal article, 2019-03-27)
      Botryococcus braunii (Chlorophyta) is a green microalga known for producing hydrocarbons and exopolysaccharides (EPS). Improving the biomass productivity of B. braunii and hence, the productivity of the hydrocarbons and ...

    • Effect of initial biomass-specific photon supply rate on fatty acid accumulation in nitrogen depleted Nannochloropsis gaditana under simulated outdoor light conditions 

      Janssen, Jorijn H.; Driessen, Jasper L.S.P.; Lamers, Packo P.; Wijffels, Rene Hubertus; Barbosa, Maria (Peer reviewed; Journal article, 2018-11)
      Triacylglycerol (TAG) accumulation in the microalgae Nannochloropsis gaditana is induced by nitrogen starvation and dependent on the light supplied. We studied under simulated outdoor light conditions the effect of supplied ...

    • Effect of removal of bacteria on the biomass and extracellular carbohydrate productivity of Botryococcus braunii 

      Gouveia, João Diogo; Moers, Antoine; Griekspoor, Yvonne; van den Broek, Lambertus A.M.; Springer, Jan; Sijtsma, Lolke; Sipkema, Detmer; Wijffels, Rene Hubertus; Barbosa, Maria (Peer reviewed; Journal article, 2019)
      Botryococcus braunii CCALA778 is a green microalga that can produce large amounts of extracellular carbohydrates and therefore is a potential host for industrial applications such as materials, food and pharmaceutical ...

    • Innovating carbon-capture biotechnologies through ecosystem-inspired solutions 

      Schweitzer, Hannah; Aalto, Nerea Johanna; Busch, Wolfgang; Chan, Dennis Tin Chat; Chiesa, Matteo; Elvevoll, Edel O.; Gerlach, Robin; Krause, Kirsten; Mocaer, Karel; Moran, James J.; Noel, Joseph P.; Patil, Shalaka Kiran; Schwab, Yannick; Wijffels, Rene Hubertus; Wulff, Angela; Øvreås, Lise; Bernstein, Hans Christopher (Journal article; Peer reviewed, 2021)
      Rising atmospheric carbon concentrations affect global health, the economy, and overall quality of life. We are fast approaching climate tipping points that must be addressed, not only by reducing emissions but also through ...

    • Lipid production in nannochloropsis gaditana during nitrogen starvation 

      Janssen, Jorijn H.; Wijffels, Rene Hubertus; Barbosa, Maria (Peer reviewed; Journal article, 2019)
      The microalga Nannochloropsis gaditana is a natural producer of triacylglycerol (TAG) and the omega-3 fatty acid eicosapentaenoic acid (EPA). TAG accumulation is induced by nitrogen starvation. The biomass-specific photon ...

    • Optimization of high-throughput lipid screening of the microalga Nannochloropsis oceanica using BODIPY 505/515 

      Südfeld, Christian; Hubáček, Michal; D'Adamo, Sarah; Wijffels, Rene Hubertus; Barbosa, Maria Hjelset (Journal article; Peer reviewed, 2021-03)
      Background Microalgae are considered a promising platform for sustainable lipid production. Despite this, productivities need to be improved to facilitate an economically viable production process. This can be achieved ...

    • Potential of novel desert microalgae and cyanobacteria for commercial applications and CO2 sequestration 

      Schipper, Kira; Al Muraikhi, Mariam; Alghasal, Ghamza Saed H.S.; Saadaoui, Imen; Bounnit, Touria; Rasheed, Rihab; Dalgamouni, Tasneem; Al Jabri, Hareb Mohammed S.J.; Wijffels, Rene Hubertus; Barbosa, Maria (Peer reviewed; Journal article, 2019)
      CO2 fixation by phototrophic microalgae and cyanobacteria is seen as a possible global carbon emissions reducer; however, novel microalgae and cyanobacterial strains with tolerance to elevated temperatures and CO2 ...

    • Translocation and de novo synthesis of eicosapentaenoic acid (EPA) during nitrogen starvation in Nannochloropsis gaditana 

      Janssen, Jorijn H.; Lamers, Packo P.; de Vos, Ric CH; Wijffels, Rene Hubertus; Barbosa, Maria (Peer reviewed; Journal article, 2019-01)
      The microalga Nannochloropsis gaditana is known for accumulating fatty acids, including the commercially interesting eicosapentaenoic acid (EPA) within the polar lipids (PL) and neutral lipids (NL). During microalgal growth ...
