AIM The growth promoting effect of the blue-green filamentous alga Spirulina platensis (SP) was observed on meat type Japanese quail with antibiotic growth promoter alternative and immune enhancing power. MATERIALS AND METHODS This study was conducted on 180 Japanese quail chicks for 4 weeks to find out the effect of diet type (vegetarian protein diet [VPD] and fish meal protein diet [FMPD])-...

The influence of aeration on algal growth and gamma-linolenic acid (GLA) production in a bubble column photobioreactor was investigated. Studies were performed in a 20-L reactor at different aeration rates (0.2- 2.5 vvm). Static, continuous, and periodic operation of air resulted in 41.9%, 88.4%, and 108% air saturation of dissolved oxygen, for which the corresponding values of GLA were 2.3, 6....

Arthrospira platensis has emerged as a novel protein feed source since it contains high level and quality. However, this microalga presents recalcitrant cell wall its main proteins form protein-pigment complexes attached to the thylakoid membrane. The objective of present study was evaluate influence mechanical/physical pretreatments (bead milling, extrusion, freeze-drying, heating, microwave s...

Extraction and purification of high-grade phycobiliproteins is a multistep process that typically involves costly chromatographic separation techniques. 3D printing approaches materials can now be tailored to fabricate low-cost anion exchange monolithic adsorbers for chromatography. In this work, new formulation was used produce discs with quaternary amine functionality. The 3D-printed were tes...

Arthrospira ( Spirulina ) platensis is a freshwater cyanobacterium that commercially produced as food source on global scale and considered safe for human consumption. After C-phycocyanin (C-PC) extraction, the waste cell residue (WCR) composed of nutrients with 30% protein content. Here, potential WCR nitrogen Bacillus coagulans cultivation bioproducts was evaluated. Nitrogen substitute from u...

There are places in our planet where environmental conditions beyond normal limits for growth but still harbour life. Extremophile microalgae the candidates large-scale production because (i) their extreme help to avoid unwanted contaminations, facilitating and (ii) order survive under harsh environments, these microorganisms synthesise valuable uncommon biomolecules. include Arthrospira platen...
