I personally have no experience with a french press. One idea might be to use a ultra fine mesh screen, like for collecting algae from water, but make a small,...
Hi Seth, ... like NaOH might have a similiar effect to soften the membrane. Remember, you make soap by mixing oil/fat and lye in the presence of water. And I...
Faith, A good point - a cream separator may be just what we need. Does anyone have access to one? Other ideas to try are a sausage stuffer and a coffee...
Faith, That's true, and you bring up a good point, but I don't know that 8g/L will cause the oil to saponify, will it? Soap making is usually done at a much...
Hi Bobby, If you mean an "old fashioned" style coffee mill, they are just a type of grist mill/grain mill. As far as I know, the steel burrs were never...
I think I would start by trying to use a juce extractor from the health foof store. If they can turn carrots into juce they should be able to turn algae into...
Faith, I have a generic Porta - Power (a very flexible hydraulic tool used to straighten wrecked auto bodies). I could use it like you suggested (and I will)....
David, Good thought. I found some on eBay from $5 up. Think I'll skip the health food store- they're usually expensive. Bobby ... -- Toward freedom, Bobby...
Hi Bobby, ... gallons of algae, my best guess is a thrift shop blender and let the result sit for 24 hours. That is a good idea! It will take a little...
Faith, Some good thoughts and questions. Comments with +++++++++++++ ... +++++++++ A good issue. I am assuming a butter fly net with a much fine mesh filter...
Hi Bobby, ... So would the algae you are looking at be anything like the cold northern ocean algaes produce oil that puts EPA and DHA into the cold water...
... We used to use a small handheld steel thing we called a french press to pulverize either frozen fungal tissue in one of the labs where I was a student. I...
Faith, They are both marine (ie,saltwater), but CCMP647 is fast growing - doubles in 2 days. It was collected in the Salton Sea and has been found as far...
Susan, Thanks for the info and digging up the web references. Sounds like, if Bill can make a piston and cylinder set, we could use my Porta - Power to push...
Faith, I don't recognize any of this, but it may contain your DHA answer: TABLE 2. Sterols of some prymnesiophytes (as percentage of total sterol). CCMP594...
How about putting it in a pillow case and running it through an old fashioned ringer? Would that be enough pressure? Chris ... From: Bobby Yates Emory To:...
Chris, We don't know yet how much pressure is needed to rupture the cell walls. We need to start with the things that are easy to do. Do you have access to...
Bobby, No I don't have access to one. I'm just trying to come up with ideas. Silly me should have taken it when I saw it years ago. Chris Sent: Sunday, March...
I just made what I think might be a useful "discovery." In quotes because I made it in my library, not my workshop/laboratory. I was looking through P&D -...
Marc, Good find. We will need this if we use oil from algae to make biodiesel. Bobby On Fri, 11 Mar 2005 13:35:27 +0800, F. Marc de Piolenc ... -- Toward...
You should mention the butanol part also. Sorry, I was the one that was talking to you on the other list. I found a guy named David Ramey worked with Noon....
Great to be back in touch - sorry I lost track. I think you could argue that ABE fermentation is relevant to OfA because bye-products are the key to making...
I just joined the group, and I'm very excited. I'm looking to sell my home (a petroleum-consuming American dream in the burbs) and buy a farm big enough to...
David, Welcome to the group. We are not yet at the "farmer producer" stage. We are beginning the "backyard experimenter" stage. But there is no reason a...
I'm not a biologist, but I've read about a condition that causes cell walls to rupture: a sufficient difference in the salinity of the cell vs the solution...
... It would certainly work, but I think it would be less preferable than mechanical means because of the introduction of more compounds to the purification...
... Other than salt, what compounds are you talking about? Also, this could, if it worked as projected, eliminate the need for pressing equipment, which isn't...
... Just salt (although other things may be neccessary; it's been a while since I exploded cells:) ... My understandign is that hexane is used to extract the...
