RM6 Formula- A Cost Effective Culture Medium For Mass Production Of Spirulina - AKA "Delhi Mix"

In 2006, a team of Algae researchers from India investigated a new culture medium formulated for the mass production of Spirulina. They modified the standard Zarrouk medium by using alternative, cost-effective nutrients while simplifying the preparation method of the chemicals being used.

Take notice that unlike the original Zarrouk formula, no liquids or dangerous acids are used in this formula, making it a safer solution for growers who lack chemistry training.

The Benefits of Using the RM6 Formula

Ease of preparation

The standard Zarrouk formula includes 2 liquids that need to be prepared in advance, the A5 and B6 solutions. Preparing these solutions is a long and possibly hazardous process, that requires chemistry training, accuracy and special care. For the common farmer, this can be a bit of a problem.

The RM6 nutrients compound does not include any liquids, making it a lot safer for growers who lack chemistry training.

Growth Rate

In comparison with the original Zarrouk formula, the maximum growth rate (in dried biomass) of chlorophyll and proteins when using the RM6 formula is almost identical in terms of production yield.

No significant differences were observed in the protein profiles of the Spirulina in both mediums.

Economic viability

Cost calculations indicate that the preparation of 1000 litres of ZM (Zarrouk’s medium) would cost about 4 times more than the costs of using the RM6 formula.

For this reason, RM6 is the basis on which several different formulas were developed and revised over the past 10 years, during which we have seen an immense growth in the Spirulina industry. One of them is considered to be the most popular spirulina growth medium in the world to this day.
