A number of drying methods studied for the processing of Spirulina (crossflow dried, spray dried and oven dried) resulted in approximately 50% loss of phycocyanin. Therefore fresh biomass was suitable for phycocyanin extraction. Of the extraction methods tested, freezing and thawing of cells, homogenisation using a mortar and pestle in the presence of abrasive material and homogenisation using ...

The emergence of antibiotic-resistant Helicobacter pylori is of concern in the treatment of H. pylori-associated gastroduodenal diseases. As the organism was reported to bind gastric mucin, we used porcine gastric mucin as substrate to assess the antiadhesive property of polysaccharides derived from Spirulina (PS), a commercially available microalga, against the binding of H. pylori to gastric ...

The current study was designed to investigate the potential effect of Spirulina platensis, Arthrospira platensis, (SP) on tissue protection of Nile tilapia (Oreochromis niloticus) through estimation of P53 level. Five isonitrogenous and isocaloric rations containing graded levels of dried SP 5, 7.5,10, 15, and 20 g/kg diet were fed separately to five equal groups of O. niloticus fingerlings, ad...

Photosynthetic unicellular organisms are considered as promising alternative protein sources. The aim of this study is to understand the extent to which these green sources differ with respect to their gross composition and how these differences affect the final protein isolate. Using mild isolation techniques, proteins were extracted and isolated from four different unicellular sources (Arthro...

The phycobilin pigments are intensively fluorescence and water soluble. They are categorized into three types: pigments containing high energies (phycoerythrins), intermediate energies (phycocyanins), and low energies (allophycocyanins). Among them, crude-phycocyanin (c-pc) has been considered to be the most preferred one. The present study was undertaken to evaluate the antibacterial activity ...

This study aimed to evaluate the effect of Spirulina platensis and moderate exercise on oxidative stress and lipid profiles in the rats. Forty male Wistar rats were allocated to the following 10-week treatments, three times a week: exercise (E, 30 min swimming), S. platensis (SP, 26 mg/Kg); exercise and Spirulina (ES); and control (C). Outcomes were Thiobarbituric Acid Reactive Substances (TBAR...

Effects of C-phycocyanin (C-PC), the active component of Spirulina platensis water extract on the expressions of N-methyl D-aspartate receptor subunit 2B (NR2B), tumor necrosis factor-α (TNF-α), interleukin-1β (IL-1β), and cyclooxygenase type 2 (COX-2) genes in the cochlea and inferior colliculus (IC) of mice were evaluated after tinnitus was induced by intraperitoneal injection of salicylate. ...

A haloalkaline anaerobic microbial community obtained from soda lake sediments was used to inoculate anaerobic reactors for the production of methane rich biogas. The microalga Spirulina was successfully digested by the haloalkaline microbial consortium at alkaline conditions (pH 10, 2.0 M Na(+)). Continuous biogas production was observed and the obtained biogas was rich in methane, up to 96%. ...

Spirulina platensis is a high protein content cyanobacterium with known therapeutic properties. Its main protein Phycocyanin is currently as a functional ingredient into various food products to enhance their nutritional qualities acting as food colorant, antioxidant and emulsifier, reducing the use of synthetic additives. The post-harvest treatment of the microalga affects its content of prote...
