Focused on the production of low cost biomass
Open ponds are continuously operated year round
Key challenge to continuous open operation is stability
Pests primarily impact stabilitySlide4

Open Algae Pond Ecology – What are the Punchlines?
SAPPHIRE ENERGY
14
There was a positive relationship between increasing species diversity and the productivity of the open algae pond.
I
ncreasing species diversity did
not increase the variance of
the open algae pond with this analysis.
Process and management strategies can impact ecology, and these impacts can be lasting.
While we
are still far from engineering open pond algae
ecosystems, these type of data suggest that open pond algae systems display some of the patterns observed in terrestrial ecosystems.
We and others are working to construct stable consortia in the lab that have productivity and stability benefits, and hope to translate those to the field to realize
the potential of the open pond platform for the continued production of low cost biomass.Slide16
