Arthrospira (Spirulina) is a well-known blue-green microalga which is applied in many areas – from human and animal nutrition to the biofuel production.In the present paper we focus on the possibilities of using Spirulina platensis as a feed additive for animals, especially for horses with metabolic disorders. Arthrospira (Spirulina) platensis biomass additive on cows’ body condition, milk productivity and biochemical indexes at the beginning of lactation. Abstract: Arthrospira platensis (A. platensis) is a micro-scopic and filamentous cyanobacterium that derives its name from the spiral or helical nature of its filaments. Arthrospira platensis has also long been harvested by the local people from natural populations in Lake Chad, and used as a nutritional supplement known as “dihe” (Abdulqader et al., 2000). J.U. 3.1 Characteristics of Spirulina Arthrospira Platensis, commonly known as Spirulina, belonging to cyanobacteria phy-lum of Eubacteria kingdom of Bacteria domain is symbiotic, multicellular green-blue algae. ): The research activity involves the analysis of Spirulina cultures (Arthrospira platensis) obtained from selected strains and reared using an air-lift photobioreactor (PBR) heat-treated with eduction water from the Carbosulcis mine using both natural and artificial light (LED) with different light spectra. Arthrospira (Spirulina) platensis as a representative species of cyanobacteria has been recognized and used worldwide as a source of protein in the food, which possesses some unusual and valuable physiological characteristics, such as alkali and salt tolerance. Arthrospira platensis is a photosynthetic, filamentous, spiral-shaped, multicellular cyanobacterium. Arthrospira spp. ...

Carbohydrates accumulated up to a content of 63.09 ± 3.43 % (±SD) in both batch and semi-continuous cultures. Panelists identified the ethanolic extract with the most pronounced algae-related odor. Microalgae addition resulted in higher swelling index and lower cooking loss than the control sample. These are useful characteristics for mass-cultivation in open ponds because these conditions can be toxic for contaminating species and predators. Arthrospira species provide exceptional nutritional value with high protein content (50–70% of its dry weight), it is rich in Dimitris Georgakakis. Selmo, M.M. 39–45, 2013.

In the current study, a native cyanobacteria strain Arthrospira platensis NIOF17/003 was isolated from the surface water of El-Khadra Lake, a saline-alkaline lake located in Wadi El-Natrun, Egypt. Food Sci. Arthrospira platensis, better known as ‘‘spirulina’’, is a motile non-heterocystous, non-N(2)-fixing cyanobacterium, that forms of a multicellular coiled filament, and it is typically found in alkaline lakes [1]. 2, 2014, p. 387-391. The cyanobacterial genus Arthrospira appears very conserved and has been divided into five main genetic clusters on the basis of molecular taxonomy markers. 1 Introduction. / Holman, Benjamin; Kashani, Arash; Malau-Aduli, Aduli. Historically mistaken for Eukaryotes, a type of fungi, it is a non-toxic species of cyanobacteria with a wide array of medical, nutritional, and commercial value. The objective of this study was to evaluate the effect of Spirulina supplementation, sire breed and sex on the wool characteristics of purebred and crossbred Merino weaned lambs under a single pasture-based management system. Arthrospira platensis is one of the phycocyanin-producing cyanobacteria and can be cultured using catfish culture wastewater. Giorgos Markou.
