Re: local algae   Message List  
Reply | Forward Message #9506 of 11589 |
All algae are wild strains (if they are not genetically modified). The culture collections are full of wild algae. Do people suggest that there are domesticated strains? I doubt so. If you look at Chlorella (which there has been GM work on) their are "wild types" and there are "mutants". The culture collections do not sell mutants so I think everything your have access to is wild. 

One thing to think about: If you get something from a culture collection that produces 90% lipids, but is impossible to grow to useable biomass, does this help you produce algae fuel?

If you grow a native species that that produces 20% but grows like a weed you will end up with at least more than with the previous scenerio. 

So the best thing is a local fast growing decent oil producer. High oil producers do exist in nature, or this whole venture would not be worth thinking about. They may take time and effort to find, but they are there (see the Aquatic Species Reports). 

Some species grow fast, some do not. Some species produce lots of lipids, some do not. Finding a combination that of these two variables, and a species that likes your growing system will ultumately determine your oil production.

Andy, Good points - I should have been more specific. It is true that almost all species in culture collections where isolated from algae found growing in the...

Bobby, We did the same with B. Braunii.. Look for oil on top of salt water ponds.. esp high pH ponds.. This is where we found B.Braunii Race B in three...

Andy and list, A posting on another list reminded me of another concern. There are toxic algae. If you collect wild algae, you may collect a toxic species. I...

Bobby,   I play alot of poker. I am used to dealing with incomplete information. I know that around two thirds of all strains have not been cataloged. I don't...

Tony, I have the impression that, out of three hundred thousand identified species, there are a couple of dozen that are toxic. So a small danger, but a...

Tony, Good point about Monti Carlo ... I think it is interesting that our system of picking alga from a Know system and using it to study the best clones of...

Bobby, I agree with many of your earlier points. Keeping things simple is often a key to success. Though I do feel that a strain worth growing is not going too...
