Cultivation Systems
TWO TYPES
Open systemsPonds, raceways
cascades
Closed or semi-closedsystems = PBRs
NETZWERK ALGEN 2018, TULLN 5
Open Production Systems for Microalgae Cultivation
NETZWERK ALGEN 2018, TULLN 6
Outdoor PBRs for Microalgae Cultivation
NETZWERK ALGEN 2018, TULLN 7
Greenhouse PBRs or Microalgae Cultivation
NETZWERK ALGEN 2018, TULLN 8
Maintenance, cleaning, contamination
OPEN PONDS RACEWAYSCASCADES
CLOSED OR SEMI-CLOSED
PBRs
o Cheap construction and
maintenance
o Cleaning easy
o Low control of culture conditions
o Evaporation – cooling !!!
o Contamination !!!
o Higher costs for construction and
maintenance
o Cleaning !!!
o Good control of culture conditions
o Cooling !!!
o Low Contamination
NETZWERK ALGEN 2018, TULLN 9
Strain selection
OPEN PONDS RACEWAYSCASCADES
CLOSED OR SEMI-CLOSED
SYSTEMS=PBRs
o Species specific
o Fast-growing, robust strains –Chlorella, Scedesmus, etc. (Chlorophyta)
o Specific conditions - Spirulina (bicarbonate , high pH), Dunaliella(high salinity), marine Nannochloropsis
o Spectrum of specieso Production strains –
Haematococcus, Chlorellamixotrophic
o Strains for high-requirementso Aquaculture strains – Isochrysis,
Tetraselmis, Phaeodactylum, Skeletoma
o Cultivation of GMO
