the natural way of course...with krill krill should be much easier to harvest than algae because they are so much larger...the food of humpback whales... ...
The krill is a small shrimp-like marine crustacean. There are 85 types of krill present in the world's oceans, the most abundant is the Antarctic Krill...
I had problems with carolina's algae being contaminated with bacillus and staphylococcus because they added a soil-water medium to provide micronutrients. I...
Jordan, (Your post lead me to three unrelated questions, so I am going to split them up.) So you are suggesting, for any inoculum with soil-water as a...
Jordan, I have seen the g/l d-1 measure being used. Since the relevant measure for an open pond is the area, wouldn't a better measure be grams per square ...
Jordan, Your point about the doubling time not telling us how much growth we were having is well taken. If the culture has just entered its exponential ...
Tom, We cannot afford the inefficiencies. Biological processes are notoriously inefficient. I doubt if we would get 10% of the oil from the algae into our ...
... We should get in the range of 10-20% of the original sunlights energy in the form of algal biomass. If conversion to krill oil is 10% we're down to 1-2%. ...
Hi, As my algal reactor design is taking its own sweet time. Can anybody supply me with algal cake or dry algae in Toronto or a link for suppliar so that I can...
hi Bobby, Do you know any custom built lens supplier in US or Canada who can build in the size of 5-6ft thanks andy ... Shape Yahoo! in your own image. Join...
Hi Gary, I would like to take the liberty to modify the algal growth curve on the group site and place the level of final D a little lower, as thats where the...
Hi Terry, The most convenient method to setup your process is by having a packed cell mass (PCM) by centrifuging a known volume and taking out the percentage...
Yes, I suppose your right about that for an open pond because light can only hit it from one direction (above) for a photobioreactor I would still use m^3....
exactly. think of biomass gained per unit area per unit time, not just biomass gained time. we need to combine the notion of a doubling time with a definition...
Another possibility, if you have a microscope, is to count the number of algae cells per "field of vision" at various magnifications. This has the added...
Anad, How much do you need? Do you have a species preference? Also, just to make sure we are on the same page, what do you mean by "algae cake"? I assume you...
Jonathan, How much dry weight algae production are you obtaining per square foot in your reactors? Gary ... Hi, As my algal reactor design is taking its own...
I have not yet determined that. I just started testing last week. My first test is running right now. I plan to harvest on Tuesday and will have some figures...
In my previous post, I mispoke when I said that Spirulina doubles every 4 days. I was going from memory, and that figure is incorrect. Spirulina doubles...
Hi Jonathan, As I am used to use the industrial term I call the harvested algae as algae cake as it comes out in cake form from the filteration press. ...
Andy, I know nothing close. My only idea would be to get the lens out of a projection TV that is busted - they have a large Fresnel lens - maybe not quite that...
Jordan, Agreed. We need to be trying to maximize the biomass added to the culture per unit area per day. Do you feel that cell density is a good measure or do...
One of our problems is drilling a well. Here is an inexpensive way to do it: http://www.howtodrillawell.com/ Catch 22s: We will need water before we can drill...
Interesting article at http://www.greencarcongress.com/2007/08/companies-to-in.html#more My comment is no 32. Kind regards Jag Kaurah ... From: Bobby Yates...
Right now, I have only 1 gram, or so, of spirulina. Spirulina has a very low oil content, but you can still work with it to test your procedures. Is 1 gram...
does any one know how they are dealing with algal toxins while cerculating the water. I beleave they will have to get a clearence before they contaminate the...
Hi Jonathan, Due to low oil content of spirulana there wont be enough oil for me to recover. I would be needing around 10gm to have oil sufficient for a Gas...
Ya now the curve looks great. The number 5 is the spot where the process will attain near max cell volume and the longer you can hold the process at that point...
I've been following algae for oil for about 7 months and I really appreciate all the information you all have put out. I work Piedmont Biofuels in North...
