chlorella pyrenoidosa vs chlorella vulgaris

Thanks to its rich nutritional content, many adore this green alga often found in freshwater. There are many species of chlorella, but two of the most popular are Chlorella Pyrenoidosa and Chlorella Vulgaris.

Both chlorella varieties abound in vitamins, minerals, and other health-promoting compounds. However, there are some significant differences between them. So, Chlorella Pyrenoidosa vs Chlorella Vulgaris, what should you use?

Chlorella Pyrenoidosa is often higher in vitamins and growth factors than Chlorella Vulgaris. It’s also a good source of beta-carotene, a precursor to vitamin A. Meanwhile, Chlorella Vulgaris contains more protein and is more easily digestible.

Chlorella’s Phylogenetic Classification

Chlorella is a genus of green algae in the phylum Chlorophyta. The genus name comes from the Greek word “chloros,” meaning “green.” 

Its full genetic line starts from the different species and rises to

  • Genus- Chlorella
  • Family- Docystaceae
  • Order- Chlorellales
  • Class- Trebouxiophyceae
  • Subdivision- Chlorophytina
  • Division- Chlorophyta
  • Infrakingdom- Chlorophyta
  • Subkingdom- Viridiplantae
  • Kingdom- Plantae

Chlorella Vulgaris

While many produce Chlorella Vulgaris indoors using the fermentation process, some grow it outdoors. 

Culturing it under fermentation offers a better chance to preserve purity, though it compromises with growth rate. Fermentation weakens the cell wall, making it more easily digestible.

Chlorella Vulgaris has slightly more protein than Pyrenoidosa. Under normal conditions, percentages are about 58% and 57%, respectively.

Chlorella Pyrenoidosa

Pyrenoidosa is an excellent species for those looking for a fast-growing alga. It contains more chlorella growth factor content than Chlorella Vulgaris, ensuring faster cell division.

Chlorella Pyrenoidosa has richer vitamin supplies, especially vitamin B12. For every 100g, it can supply as much as 434.6 micrograms of B12

That means a 10g dose gets you 43.46 micrograms of the vitamin. As a result, it offers more than enough, surpassing the daily requirement (2.4 micrograms) by over 1000%.

Is Chlorella Pyrenoidosa Unicellular?

Chlorella Pyrenoidosa is a single-celled (unicellular) green alga with a diameter of 2-10 μm. The implications of this are that the cell is the only fundamental unit of structure and function in the organism.

A unicellular cell handles all the functions that keep the organism alive, like metabolism, reproduction, and movement. Being unicellular also means that the cell can divide to produce more cells (binary fusion). This method aids chlorella cells in growing and repairing themselves.

Difference Between Chlorella Vulgaris and Chlorella Pyrenoidosa

Both varieties are rich in chlorophyll, proteins, growth factors, and more. You can get them in various forms, including chewable tablets.

However, as shown in this table, they differ in a few ways, like protein, CGF, and B12 percentages.
