greater than 3,000 ppm dissolved solids

About 1,000 ppm dissolved solids

Light sensitivity

Grows in high intensity light


Grows best in low light intensity

Grows in high light intensity

Nitrogen metabolism


Metabolises molecular nitrogen from the air to produce protein, nucleic acids and other nitrogen containing compounds


Grows on nitrates, nitrites and ammonia

Grows on nitrates and ammonia

Net Protein utilisation

High protein assimilability - NPU greater than 75% (Freeze dried material)


Assimilable protein - NPU about 37% for spray dried material

Low assimilability - NPU about 20%

Low molecular weight peptide & neurotransmitter concentrations


Has high concentrations of neurotransmitter-like compounds due to its breatharian characteristics


Contains low levels of molecular weight peptides when grown in adequate concentrations of ammonia or nitrates

Contains small amounts of controlled growth factor elements

Cell wall characteristics

Soft cell wall consisting of a glycoliproprotein complex

Soft cell wall constructed of a protein/mucopolysaccharide


Contains cellulose cell wall that is not digestible

Denaturation of cellular constituents during processing


Cellular components remain intact during freeze-drying

Enzymatic activity is lost during spray drying

Remains intact if freeze dried

Vitamins and minerals

Bioavailability remains high during freeze-drying process


Heat sensitive components are degraded during spray drying


Low bioavailability due to cellulose wall
