Protein and carbohydrate extraction from S. platensis biomass by ultrasound and mechanical agitation.

Spirulina platensis is considered an alternative and excellent source of protein [46-63% dry basis (DB)], having protein levels comparable to meat and soybeans. Thus, it can be considered an adequate ingredient to supply the necessity of this compound in the food industry. Its carbohydrates (8-14% DB) may also be a useful food ingredient or a potential source of bioenergy.

Potential application of microalga Spirulina platensis as a protein source.

The high protein level of various microalgal species is one of the main reasons to consider them an unconventional source of this compound. Spirulina platensis stands out for being one of the richest protein sources of microbial origin (460-630 g kg , dry matter basis), having similar protein levels when compared to meat and soybeans. The use of S.
