“…Taking into account the contents of minerals, proteins, carbohydrates and lipids present in Spirulina strain LEB-18, an interesting result of these nutritional components in a single source was observed. The study of Moreira et al (2013), in which malnourished rats were fed for 30 days with a diet supplemented with S. platensis LEB-18, had great findings regarding the hematological and biochemical profile of blood, thus indicating the cyanobacterium studied as an excellent supplement for human consumption.…”

The aim of this study was to determine elemental constituent of microalgal biomass Spirulina platensis LEB-18 grown on the shores of Mangueira Lagoon, South of Brazil. The spread of inoculum was performed in standard Zarrouk medium. When the microalgae concentration reached 0.50 g L-1 , the biomass was separated by filtration and dried in a tray dryer at 50°C for 5 h. The harvested biomass was then ground in a ball mill, sieved to achieve a particle size of 88 µm (~ 300 mg) in triplicate, digested with concentrated HNO 3 and diluted with up to 5% HNO 3 for subsequent quantification. Mineral content was determined by inductively coupled plasma optical emission spectrometry with axial view and other nutrients by standard methods. Among the macro minerals, in μg g-1 ± standard deviation, calcium (15.108±529), sodium (14.6552±485) and potassium (14.036±109) were found in the largest amount. The micro mineral present in greater quantity, in μg g-1 ± standard deviation, was the iron (956±9) and nutrients present in the following order: protein (58.5%), ash (12.0%), carbohydrate (7.5%), lipid (7.0%) and crude fiber (0.95%). Results were compared with the values of minerals for human consumption recommended by the Food and Drug Administration and also with the Recommended Daily Intake (RDI) of minerals by Brazilian Legislation. The findings proved promising for the use of S. platensis strain LEB-18 as an alternative source of essential minerals and other nutrients for the human body.

“…biomass are consistent with reports for commercially-established algal species like Spirulina and may provide a unique and highly-marketable property for certain algal products/coproducts. From an animal health perspective, new data has recently emerged that indicates that feeding diets supplemented with Fe-rich algal biomass to pigs and rats significantly increased erythrocyte volumes and blood hemoglobin concentrations [75][76][77] and this area warrants further investigation. Ca and P are the most critical essential minerals involved in the development and maintenance of the skeletal system and maintaining acid-base homeostasis in farmed animals and fish [39,50].…”

“…The rats were maintained on AIN 93G as the basal diet (Reeves et al 1993). The overall proximate composition of P. purpureum-mixed feed was maintained unaltered to the AIN 93G diet by adding the protein (casein) and cellulose (fiber) as required, after deducting the intrinsic amount present in P. purpureum (Moreira et al 2013), every 7 days once the diet was prepared for subchronic study and stability of diet was ensured by storage at 4°C.…”

Acute and subchronic safety assessment of Porphyridium purpureum biomass in the rat model

et al. 2015

Porphyridium purpureum biomass was assessed for its acute and subchronic safety in albino Wistar rats and for its use as animal feed/human food application. P. purpureum contained 29.9 % protein, 7.99 % lipid, and 2.98 % phycoerythrin on dry basis. Polyunsaturated fatty acids constituted >50 % of the total fatty acids (53.9 % w/ w), with eicosapentaenoic acid as the predominant ω3 (21.9 %) and arachidonic acid as the predominant ω6 fatty acid (15.7 %) with an overall ω6/ω3 ratio of 0.42. The essential amino acids (EAAs) constituted 37.97 % (w/w) of proteins with leucine as the predominant amino acid (10.99 %). The EAA index was similar to casein and soybean proteins. Water absorption capacity (WAC; 3.86±0.01 g water g −1 biomass) and oil absorption capacity (OAC; 3.57±0.04 g oil g −1 biomass) were six times higher compared to the basal diet (WAC 0 . 6 6 ± 0 . 0 0 7 g w a t e r g − 1 f e e d a n d O A C 0 . 5 7 ± 0.02 g oil g −1 feed). The acute toxicity study showed that the biomass was safe at acute doses and LD 50 exceeded 5.0 g kg −1 body weight, the highest dose used in the study. In a subchronic study, rats were fed a diet containing 0, 2.5, 5.0, 7.5, and 10.0 % levels (w/w) for a period of 13 weeks. The biomass fortification did not induce any untoward changes in physiology such as body weight gain, relative organ weights, histopathology, and hematological and serum biochemical indices. However, supplementation of P. purpureum biomass resulted in decreased serum cholesterol and triglyceride levels compared to control groups indicating its high nutritional value.
