Nutritional evaluation of single-cell protein produced by Spirulina platensis

摘要: The aim of this research was to evaluate the nutritional characteristics and possible toxic effects microalgae Spirulina LEB-18, developed in south Brazil. biomass evaluated for 40 days through responses, obtained by development Wistar rats also biochemical hematological study blood these animals. Four isoproteic diets were prepared (12% protein): (1) Control diet, 12% (w/w) casein; (2) Diet S1, 8.8% Spirulina; (3) S2, 17.6% (4) S3, 26.4% Spirulina, distributed animals according their treatment (n = 6). As parameters S1 more efficient. groups did not differ regard determinations blood, with exception which showed creatinine levels lower than all others. In hematologic profile, S3 hematocrit hemoglobin greater control diet. These results revealed no toxicity use it suggests as a potential source single-cell protein. Key words: Cyanobacteria, growing rats, evaluation, Spirulina.
