Spirulina can grow in BG11 media but pH must be 9-10

Zarrouk's medium is the best one Spirulina..

You can use BG-11 medium + Vitamin B12 supplement as enrichment media 

yes you can Isolate of Spirulina spp. and performing by streaking plate method of Stein (1973) using BG-11 agar medium.

you can use BG-11 Medium to isolate spirulina spp.

Spirulina is one of those things that grows for a while and then dies for no obvious reason.  It will grow in BG-11 plus 100 mM Sodium carbonate and 1 M NaCl.

The cosmic organic goodness Spirulina pills you can buy in health stores are usually viable and you usually can get a culture going by just throwing a pill into some sterile medium.

Hi dear Lawrence

Yes, Spirulina Spp can growing in BG11 culture medium, but Zarrouk medium is better than other culture media for growing Spirulina Spp in laboratory scale.

In oder than, Zarrouk’s medium (ZM) was the best medium in terms of biomass productivity, while BG11 medium gave the highest chlorophyll, carotenoid, phycocyanin, and allophycocyanin contents.

Good luck

Good question,

I have grown Spirulina platensis in BG11 medium. It didn't yield the same and since the salinity and buffer capacity is so low you have to work really sterile to do so. Many other algae and alike can grow in it compared to Zarrouk's medium where the pH and salinity keep the contaminations out or dormant. So it can be done but it is harder.

I have made this page listing all the medium, and their recipes, that have been used to grow Spirulina: https://www.healthalgae.com/spirulina-medium/
