Spirulina

[Reville]

You know im having a bugger of a time finding a place or person that has spirulina live cultures?

there is plenty of teks out there on how to grow it in your backyard
but i just dont see it

itd be simple enough to 1/3 fill a test tube and stick it in the mail. maybe theres just no demand?

can anyone elnlighten me please

Hi Reville,

itd be simple enough to 1/3 fill a test tube and stick it in the mail. maybe theres just no demand?

My understanding is that Spirulina is harvested using a centrifuge......and that's probably the principal obstacle to people growing it on small scale.

Ok thanks

A centrifuge is pretty easy to get

desk top test tube units can be had from Lab supplys

i was looking at getting a reconditioned one from a place that repairs labware


the teks ive seen suggest its pretty low tek

see the open ponds



and the guy harvesting with a fine sieve net



strain and green putty




what ive read says you need

heat- tick
strong sun - tick
salt
soda
fertiliser

i was interested partly for myself
but also as a food for fish fry or for live food

ive seen and done work experience at the Freo fish farm in the microalgae section.
it was a good experience and now i think back i realise how simple and streamlined a process it was.
Ive since been to uni and grown lots of things in test tubes, and micropropagted plants. and the process seems a fusion.

ive also visited pearl oyster hatcheries wher ethe algae are growing im thos same 1000L white transparent molasses tanks we use cut down as AP units with a bubbler in it


first thing is however a clean culture
Im sure S platensis would occur in the mangroves near me at low levels but id have to sort through a lot of junk to find it and isolate it
and even then i wouldnt know if it was S platensis now Arthrospira platensis???

oh well. another idea to put on the shelf for now and revisit periodically

this was interesting anecdote from

Incidentally the very expensive Spirulina from California (Earthrise) is
freeze dried. The cells in the pills are viable and can be used to start a
culture of it if you need to.

i might give it a go
