Why Do We Want (Need!) To Do This?
• Ecological Necessity
– Atmospheric Effects of Increasing CO2 Concentrations
![Page 5: CO 2 MITIGATION, FUELS AND FOODS FROM MARINE PHOTOSYNTHETIC MICROBES.](https://reader035.fdocuments.us/reader035/viewer/2022062313/56649d5d5503460f94a3cf6e/html5/thumbnails/5.jpg)
Atmospheric CO2 concentrations since the year 1000 AD estimated from
ice core data and monitoring of CO2 at Mauna Loa.

Increasing CO2
Atmospheric CO2 isnow 370 ppm -
a value not exceededin the past 20 million years
Source: Intergovernmental Panel on Climate Change (IPCC) 2001

Why Do We Want (Need!) To Do This?
• Ecological Necessity
– Oceanic Effects of Increasing CO2 Concentrations

Ocean Acidification
ΔpH
Coral reefs, molluscs, and other marine life formsare threatened
Caldeira & Wickett (2003)“Anthropogenic carbon and ocean pH”Nature 425 (6956): 365
As pH decreasescalcification diminishes
The marine food web will change – for at least 1,000 years
![Page 9: CO 2 MITIGATION, FUELS AND FOODS FROM MARINE PHOTOSYNTHETIC MICROBES.](https://reader035.fdocuments.us/reader035/viewer/2022062313/56649d5d5503460f94a3cf6e/html5/thumbnails/9.jpg)
Impact of Increased CO2-Associated Ocean Acidification on Marine Food Chains
Eukaryotic phytoplankton - diatoms, coccolithophores, & dinoflagellates.
Diatoms are favored in a dynamic, turbulent ocean (today); they will be less competitive in a stratified, steady state ocean (tomorrow).
Coccolithophores are very competitive in stratified systems, but produce calcium carbonate plates; ability to compete will be compromised as the ocean becomes more acidic.
Dinoflagellates will be the winners;
many Harmful Algal Blooms are dinoflagellates.

Health Effects Associated with Dinoflagellates
Diarrhetic shellfish poisoning (species of the genus Dinophysis).
Neurotoxic shellfish poisoning (Karenia brevis),
Paralytic shellfish poisoning (species of the genera Gymnodinium, Alexandrium, and Pyrodinium).
Ciguatera fish poisoning (Gambierdiscus toxicus).

Photobioreactors
• Advantages– Controlled, optimized conditions– Contamination can be minimized– High rates of production
• Disadvantages– Expensive

Open Ponds
• Advantages– Economical– Relatively simple
– High rates of production possible
• Disadvantages– Potential for contamination (competitors, invaders)– Less control of conditions (e.g., pH, Temp)

A Problem for Solazyme, A Potential Opportunity for UH
• The Navy wants Solazyme to produce biofuel in Hawaii
• Solazyme’s technology uses GMO algae
• Hawaii Dept. of Ag won’t allow GMO algae into the state
• Solazyme may have UH engineer the algae to their specifications
