Growth of Spirulina maxima was studied in three types of culture conditions with four replicates each: 1) manual aeration with natural sunlight; 2) manual aeration with artificial light; and 3) constant aeration with an aquarium compressor and artificial light. After 185 days of incubation, growth declined in the first two treatments, while in the third treatment, higher growth was observed with average optical density of 3.7 against 1.8 and 1.9 in the first and second treatment, respectively. This was probably due to the fact that under constant aeration the salts were suspended avoiding the crystallization what could cause a decrease in the availability of the necessary nutrients for the growth. Also, the constant stirring allowed all the cells to...

The aim of this work was to investigate the production of phycocyanin by Spirulina platensis under different spectra of light. The dependent variables evaluated were the amount of phycocyanin obtained and its purity, demonstrating that there might be a restructuring of phycobilisomes, especially when the culture was subjected to red light, which increased the purity level up to 33% with a reduction of 16% in phycocyanin content, but with higher photosynthetic efficiency compared to natural light.

Abstract The biological assimilation of the sugars present in lignocellulosic residues has gained prominence since these residues are the most abundant and economic residues in nature. Thus, the objective of this work was to determine whether the use of D-xylose and L-arabinose as sources of carbon in Synechococcus nidulans and Spirulina paracas cultures affects the growth and production of proteins and carbohydrates. Kinetic growth parameters, pentose consumption, protein content and carbohydrates were evaluated. Synechococcus nidulans and Spirulina paracas consumed all concentrations of pentose used. The highest cellular concentration (1.37 g.L-1) and the highest protein productivity (54 mg.L-1.d-1) were obtained for Spirulina paracas, which was...

This study was aimed at evaluating the effects of Spirulina (Arthrospira) as a protein source in the nutritional recovery of rats subjected to protein malnutrition. In order to understand such effects, responses of the developing body, serum biochemical profile, and blood count of animals were analyzed. A total of, 23 Wistar Rattus norvegicus were given a proteic diet (AIN-93G adapted) in malnutrition phase (phase I) for 10 days. After this period, the rats were separated into four groups according to the protein source (recovery phase): Control (C), casein 12%; Spirulina level I (S1), Spirulina 8.8% + casein 5.0%; Spirulina level II (S2), Spirulina 17.6% + casein 0.15%, and Spirulina level III (S3), Spirulina 26.4%. Recovery phase (phase II) lasted 30...

In the present study, the effects of Spirulina on subchronic treatments (two weeks) of hyperlipidemia and liver function of the rats and humans were investigated. The hyperlipidemia was induced in the rats using 25% of soya bean oil and 25% butter. The butter induced more hyperlipidemia than soya bean oil. Spirulina was used at the concentrations of 0, 2.5, 5.0 and 10 % of diet weight of the rats. The decrease in hyperlipidemia by Spirulina was dependent on its concentration in the diet. In case of human studies, about four g/day of Spirulina was taken via oral administration by Egyptian volunteers patients with hyperlipidemia. Spirulina decreased the levels of hyperlipidemia in these patients. The effects were dependent on the amount and number of...

Studies have been conducted on microalga Spirulina platensis (Arthrospira platensis) due to its therapeutic potential in several areas, including the capacity for preventing and decreasing the damages caused by hyperlipidemia and the antioxidant activity. The aim of the study was to evaluate the effect of microalga Spirulina platensis on hippocampus lipoperoxidation and lipid profile in rats with induced hypercholesterolemia during 60 days. The measurement of hippocampus lipoperoxidation did not demonstrate significant difference (p>0.05) when Spirulina platensis was added to hypercholesterolemic diet. The evaluation of lipid profile showed that the administration of the microalga in therapeutic and preventive ways led to a significant protective effect...

Paclitaxel spirulina nanoparticles were said to have promising anticancer activity against gastric cancer. Nanoparticles of paclitaxel-spirulina were prepared for treating gastric cancer using precipitation technique. The synergistic anticancer efficiency againstMKN45 cells retains when the paclitaxel and spirulina were encapsulated into nanoparticles. To increase the site specific delivery, intra-tumoral administration was carried in the in vivo evaluation. There was an increase in overall survival in an MKN45-transplanted mice model and notable improvement in anti-tumour efficacy when paclitaxel-spirulina nanoparticles were delivered through intra-tumoral administration. The further investigation of overall anticancer mechanism of these nanoparticles is...

As microalgas são consideradas fontes potenciais de diversos compostos químicos. Os ácidos graxos obtidos da biomassa podem apresentar efeitos terapêuticos em humanos e podem ser usados para produção de biodiesel. Objetivou-se, neste trabalho verificar o conteúdo lipídico e o perfil dos ácidos graxos das microalgas Spirulina sp., Scenedesmus obliquus, Chlorella kessleri e Chlorella vulgaris cultivadas em diferentes concentrações de dióxido de carbono e bicarbonato de sódio. A microalga Chlorella kessleri cultivada com 12% de CO2 apresentou a maior concentração de lipídios na biomassa seca (9,7% p/p). A máxima concentração de ácidos graxos insaturados foi 72,0% (p/p) para C. vulgaris cultivada com 12% de CO2. Para os ácidos graxos saturados o maior valor...

The microalgae biomass production from swine wastewater is a possible solution for the environmental impact generated by wastewater discharge into water sources. The biomass can be added to fish feed, which can be used in the formulation of meat products. This work addresses the adaptation of the microalgae Spirulina platensis (Arthrospira platensis) in swine wastewater and the study of the best dilution of the wastewater for maximum biomass production and for removal of Chemical Oxygen Demand (COD), ammonia and phosphorous to the microalgae. The cultivation of Spirulina platensis, strain Paracas presented maximum cellular concentrations and maximum specific growth rates in the wastewater concentration of 5.0 and 8.5%. The highest COD removals occurred...

A microalga Spirulina maxima foi cultivada em meios com 2,5g/L KNO3 (2,5N), proposto por PAOLETTI et al [10] e considerado meio padrão, em meios com 0,2g/L KNO3 (0,2N) e em ausência de nitrogênio (0,0N) nas temperaturas de 25°C e 35°C. A composição da biomassa celular seca apresentou a 35°C um aumento médio dos lipídios totais, de 2,8 vezes do meio com ausência de nitrogênio (0,0N) e 2,9 vezes do meio 0,2N em relação ao meio padrão. A 25°C apresentou um aumento médio de 3,1 vezes do meio com ausência de nitrogênio (0,0N) e 3,2 vezes do meio 0,2N em relação ao meio padrão. A biomassa em forma de gel de cada tratamento foi recolhida e feita a extração dos lipídios totais, os quais foram pesados em base seca. As análises estatísticas dos resultados, em...

Abstract Health safety of spirulina (Spirulina platensis) for food application was evaluated through hematology and histopathology of liver, spleen and kidney in Sprague Dawley rats fed on three isoproteic diets maintained to 10% protein for forty five days. Three groups of rats were maintained as control diet casein (R-C); diet containing crude spirulina (R-S) and diet containing purified spirulina protein (R-SPI). Hematological profile of the rats group fed on spirulina diets showed no significant increase in white blood cells (WBCs), while there was decreasing trend in the levels of neutrophils (60.46 ± 2.60%) and lymphocytes (33.53 ± 1.06%) in rats that were fed on spirulina diet (R-S) than the other tested experimental diet group. Histopathological...

Spirulina maxima é uma cianobactéria de grande interesse para a produção de substâncias nutritivas e terapêuticas. É mesofílica, essencialmente fotoautotrófica, sendo suas principais fontes de nitrogênio os nitratos, uréia ou sais de amônio em meios com alta alcalinidade [1, 2, 3, 10, 16]. Spirulina maxima foi cultivada em fermentadores, expostos a luz com intensidade de 2400lux, contendo 3L do meio proposto por PAOLETTI, PUSHPARAJ & TOMASELLI [7] com concentração de 2,5g/L de KNO3, em meio modificado com 0,2g/L de KNO3 e em meio sem fonte de nitrogênio, denominados respectivamente meios 2,5N, 0,2N e SN, visando observar as alterações provocadas em sua composição final. Em culturas crescidas a 35ºC observou-se redução do teor de proteínas na massa...
