Can algae replace commodities of today?
 European market:
● Fossil fuels:
400
● Polymers and chemicals: 100
● Palm oil:
7
● Soy:
8
 Global microalgae market today:
● < 10,000 tonnes/year

Develop this process
is a sustainable and
economical way
within the next 10 15 years
To develop a more
sustainable and
economically feasible
process, all biomass
components should be
used
From basic to applied research
 Resources
● Efficient use of sunlight
● Reduction of energy input
● Use of residual nutrients
 Strains
● Lipid accumulation
● Metabolic Engineering
 Implementation
● Scale-up
● Biorefinery
● Design scenarios/LCA’s
Photobioreactor design


Antenna size mutants
● Light-saturation at
higher light intensity
● Less energy wasted.

Behaviour during day/night cycles
Lenneke de Winter
• The aim of this research is to obtain more knowledge in the circadian behaviour
of the cell cycle of lipid producing microalgae grown in photobioreactors. This
will provide ways to optimize the current production process under outdoor
day/night cycles.
• Neochloris oleoabundans is grown in a lab-scale photobioreactor under
simulated outdoor conditions.
• The circadian rhythm of the cell cycle is analysed using flow cytometry.
• In addition, cell composition (lipids, starch, proteins) during the cell cycle is
investigated.

Genetic engineering
 Lipids
Stefan Aanstoot
● Strain improvement towards a desired
fatty acid profile
● Strain improvement towards a increased
TAG production
 Hydrocarbons
● Botryococcus
● Insert Botryococcus genes for
hydrocarbons in Chlamydomonas
 Mutagenesis and direct gene targeting
approaches

AlgaePARC
 Basic research is not sufficient
 Gap between basic research and
commercial applications
 Continuous interaction between
basic research and pilots
 Follow up in
demonstrations
 Products
 Scale
 Production chain
AlgaePARC
 International centre of applied
research
 Intermediate between basic
research and applications
 Development of competitive
technology (economics,
sustainability)
 Acquire information for full
scale plants
 Algal biomass for food, feed,
chemicals and fuels
