QUESTION:

I'm interested to learn the dry matter contents of various species of
algae, such as Chaetoceros sp., Isochrysis galbana, Thalassiosira
pseudonana.

Secondly, where is the primary amount of lipid stored in algal cells?
Obviously some will be in the cell membrames, but are there also
storage vacuoles for lipid?

Breakdown on dry weight basis for:
Schizochytrium under commercial listing of AlgaMac-2000:
Protein: 39%
Lipid: 32%
Carbohydrate: 13%
Ash: 12%

Of Fatty acids, DHA = 7-8%

Schizochytrium under commercial listing of AlgaMac-3010:
Protein: 19.5%
Lipid: 55.9%
Carbohydrates: 17.1%
Ash: 4.4%

Of Fatty acids, DHA = minimum 15-17%

Schizochytrium is a heterotrophically grown organism
which has replaced algae in some applications and is well
suited for enrichment purposes.
