If you know someone who has live spirulina producing biomass for biogas production, could you please be so kind to share? I'm asking for health reasons. I already got the aquarium, nutrients and iron solution. Look forward tk your reply... I will pay for all expenses, you got nothing to lose.

check with your local community college or university. If they have a class in microbiology, you'll hit the jackpot. Just pop by and chat with one of the microbiology professors. Trust me, what those poor professors normally do with their office time is a chore; talking shop with you (community outreach) will be far more interesting than anything else they have going on.

Tried everything... university marine department, commercial companies, individual farmers and even teachers... the best I got was "fork over 60 bucks and pray that it arrives to you alive in the mail"... Dunno about others but $60 for a shot in the dark seems risky and expensive. Company reps say it violates their commercial license to share... I even got a guy with half a dozen swimming pools living a few miles away who is very talkative but when the conversation changes from buying his seminars to sharing a tablespoon of spirulina for biomass production his conversation suddenly dies... unbelievable... But where others see emptiness I see possibilities... was even thinking about starting a croudfunded project like spirulinasystems dot com did last year in kickstarter dot com for biomass production and development through the use of algae.

you can buy a live cultures here for $25.

Stick it under a microscope as soon as it arrives. It should look like this:

Hot Dog! Now, that's a good find. $25 with shipping included.

Already bought it yesterday... trying to negotiate some last minute shipping details to ensure that it arrives alive in the mail this time.

I already lost count of how much time and money I've spent buying spirulina just to watch it arrive dead in the mail. That's why I say that the spirulina in that video looks quite beautiful and healthy and probably taken from a fresh culture, but it's not what I see in the microscope when it arrives in the mail...

What I usually see is not opaque green strands but rather semi-transparent ones with hard to tell outlines and a color that looks like a faint yellow with a little taint of green and they definitly don't curl half a dozen times like in the video but only once or once and a half times... I think when it reaches that stage it is already breaking down and dying beyond hopes of reviving. Spirulina preserves inside a closed bottle in the dark kinda like raw eggs.

Again, thank you for that link +1

Great find on the website. Has anyone order with that producer? What is the quality of his spirulina?

Aleluia, finally got it... cost me almost an arm and a leg but finally got it.

I want to thank for all the help I got here because I bought many times before spirulina delivered in the mail but always arrived dead and smelling like rotten eggs, this time had to do a long, time, money and effort consuming trip into unknown lands to to meet a spirulina grower in person and then carry a 5 liter bottle in my lap back home as fast as possible to put it quickly into the growing medium in less than 10 hours. Also tried growing a batch that I harvested myself two days before departing but was nearly dead when I arrived home and also placed it in the growing medium.

My first goal now is learning how to keep it alive and I am still experimenting with different kinds of nutrient solutions at different concentrations with different environments, etc, etc...



but I already found 2 kinds of nutrient solutions that are producing well and everyday I harvest half of this floating layer on a daily basis and next day is full again



I use two bottle like that to start new cultures and to compensate for the ones that die by mistake of mine and this next one I started yesterday and today it is already visible around the borders a layer of spirulina growing thick:



And for what I've seen I'm getting approximately 10 per cent of straight filaments... so, it is not so hard to harvest



Tomorrow or maybe after tomorrow when I have time let's start the excavation of a pond for growing spirulina.

...

Ufff... finally...

it was almost 1 year that I spent running around to catch this green thing.

Hi
The Great adventure has begun ... Ive started growing my own Spirulina culture ... its only been 9 days. And after a week and a bad start, a bad instruction manual said to add culture to nutrient liquid and wait 3 days add more nutrient liquid... I thought it meant to add the liquid nutrient mix undiluted. So I mixed 10Litres worth of nutrient with my 100mls spirulina culture . ...  Thankfully, its flourishing nicely now ... after7 days  I added 2L of water and a heaped of the bicarb nutrient powders. It has regained and flourished immensely overnight now only 2 days later .. I have 5x the amount of culture before it just about died.

My question is,

I am looking to use an organic  plant based liquid nutrient feed to put in the spare feeding tank for my algae.  Am I able to use a Bunnings bought organic liquid nutrient for plants as feed for my culture? Do you know which one is most suitable and the amount to use for a 10L tank?
Thank You
