This study explores the influence of wastewater feedstock composition on hydrothermal liquefaction (HTL) biocrude oil properties and physico-chemical characteristics. Spirulina algae, swine manure, and digested sludge were converted under HTL conditions (300°C, 10-12 MPa, and 30 min reaction time). Biocrude yields ranged from 9.4% (digested sludge) to 32.6% (Spirulina). Although similar higher ...

  This experiment was carried out in Bandargah Station in Bushehr province. Peneaus semisulcatus larvae were fed on Spirulina platensis as supplementation microalgae. In order to use spirulina platensis in this study, we have to produce biomass and dry production of this microalga. Determination of length and survival rate of Peneaus semisulcatus larvae was carried out as the objective of the s...

Undernutrition constitutes a public health problem particularly in developing countries. The utilization of algae, particularly Spirulina, as a functional food was suggested decades ago due to the fact that it is not only a protein-dense food source, but because its amino acid profile is considered as of high biologic-value protein content. Spirulina provides essential fats (e.g., gamma-linolen...

The response of Spirulina platensis cells to salinity stress was studied. Once adapted to the higher osmoticum, photosynthetic parameters such as the maximum rate of photosynthesis under saturating irradiance (Px) and the initial slope of the P-I curve (a) are reduced by 15% and 25% in 0.5 M NaCl grown cells, respectively. Salt-adapted cells have a modified biochemical composition; reduced prot...

Ramadan M.F., Asker M.M.S., Ibrahim Z.K. (2008): Functional bioactive compounds and biological activities of Spirulina platensis lipids. Czech J. Food. Sci., 26: 211–222. The compositions and concentrations of lipid classes, fatty acids, tocopherols were determined in the lipids from blue-green microalga Spirulina platensis. Total lipids (TL) recovered using chloroform: methanol (2:1, v/v) were...

The pathogenesis of nonalcoholic steatohepatitis (NASH) remains unclear, but accumulating data suggest oxidative stress and the relationship between inflammation and immunity plays a crucial role. The aim of this study is to investigate the spirulina, which is a blue-green algae rich in proteins and other nutritional elements, and its component-phycocyanin effect on a rat model of NASH. NASH mo...

Spirulina platensis, is a photosynthetic, filamentous, spiral-shaped, multicellular and bluegreen micro alga. As it contains chlorophyll a, like higher plants, botanists classify it as a micro alga belonging to Cyanophyceae class; but according to bacteriologists it is a bacterium due to its prokaryotic structure. Mexicans (Aztecs) started using this microorganism as human food. Its chemical co...

Anticataract activity of Ambroxol, Spirulina and Vitamin E was examined using the naphthalene cataract model. Adult female albino rats of Wistar strain weighing between 180 and 220 grams were taken and divided into eight groups. Group I received light liquid paraffin 5 ml/kg/ day p.o. for 6 weeks. Group II received naphthalene solution 0.5 gm/kg/ day p.o. for first three days and 1 gm/kg/day p....

Background: Spirulina is a cyanobacterium blue-green alga rich in a wide range of nutrients include; protein, lipids, high level of various B vitamins, and minerals including calcium, iron, magnesium, manganese, potassium and zinc. Aims: The objective of this study is to assess the impact of nutritional rehabilitation using Spirulina platensis versus vitamins and minerals supplementation on the...
