MICROALGAE DIVERSITY - not all the same!• 30 000 described species (< 10% of estimated)• 11 Divisions divided into 29 classes (vs. 2/12 vascular plants]J. Benemann, 5 th Annual World Congress on Industrial Biotechnology, Chicago, April 30, 200812
SO, WHY MICROALGAE? REALITY CHECK• grow faster Not all that relevant (except for R&D)• more productive Possibly but not proven (need R&D!)• use power plant flue gas CO2 A need, not a virtue• have high oil content OK, but must be productive (R&D)• use saline, brackish, waste waters Yes, use less water• do not compete with agriculture We could eat algae!• Low cost of production / processing Not true!• Very Large production potential Many limitations• Co-products, Nutrient recycle, waste treatment YES!So, why Microalgae? Likely will not be a panacea, but dohave applications for biofuels and we must try and develop13all plausible biomass resources, including pond scum!J.
