Analyses of algal biomass

  • carotenoid and chlorophyll content (spectorophotometer)
  • carotenoid and chlorophyll profiling by HPLC, including esterified carotenoids such as astaxanthin
  • phycocyanin content in Spirulina
  • total lipid content according to Ryckebosch et al. (2011)
  • separation of lipid classes (neutral, phospho- and glycolipids)
  • fatty acid analysis of total lipids and lipid classes using GC (range from 8:0 to 24:1)
  • free fatty acid content
  • degree of lipid oxidation
  • protein content and amino acid profiling
  • phytosterol and cholesterol analysis
  • antioxidant activity, using TEAC, FRAP, AIOLA and square wave voltammetry
  • carbohydrate content and composition
  • polyphenol and flavonoid content
  • ash content and analysis of major minerals

Experimental services

  • batch, fed-batch and continuous production of microalgae in lab (1-2 L)
    and pilot scale photobioreactors (30-120 L) or raceway ponds (30 L)
  • experiments with economically relevant microalgal model species
    (Chlorella, Phaeodactylum, Nannochloropsis, Spirulina/ Arhtrospira, Scenedesmus, Microcystis, Pavlova, Tetraselmis, Haematococcus, Botryococcus)
  • flocculation of microalgae: pH-induced auto-flocculation, electro-flocculation, flocculation using metal salts or biopolymers
  • harvesting by cross-flow membrane filtration, cenrifugation, and freeze-drying facilities
  • lab-scale extraction and biorefinery
  • microalgal growth assays in wastewater, including nutrient removal efficiency
  • Pulse Amplitude Modulated fluorescence (PAM) measurements for algae viability evaluation
