Abstract This study investigated the impact of struvite as a sustainable phosphorus source on growth and phycocyanin production by blue-green alga Arthrospira platensis . Three modified media were compared to typical SAG-spirul culture media. CS(+) refers completely recycled from bovine urine phosphate source, while S(-) S(+) refer commercially available source. On with (+), pre-treatment was c...

Aquaculture wastewater is suitable for algal growth especially due to its ammonium and nitrate content. Therefore, the can be utilized after a few amendments biomass production recovery of valuable pigments. In present study, aquaculture discharged from Pangasius culture system was commercially cyanobacterium Spirulina (Arthrospira) platensis with an aim extract economically important pigments ...

Cyanobacterial harmful algal blooms (cyanoHABs) have been observed across the USA and worldwide, even locally in Lake Fayetteville (Arkansas, USA) once we started monitoring for total microcystin. The goal of this research note was to present a framework that might help guide cyanoHAB toxin public health advisories at Fayetteville. We evaluated nonparametric change points (i.e., thresholds) hie...

A strain of the filamentous non N-fixing cyanobacterium Phormidium sp. isolated from Messolonghi (W. Greece) saltworks, was cultured in laboratory at six different combinations salinity (20-40-60 ppt) and illumination (low-2000 lux high-8000 lux). At salinities 60 40 ppt high (XL-8000 lux), growth rate (?max) presented highest values (0.491 0.401, respectively) compared to corresponding 20 (0.2...

The chromophore of C-phycocyanin, phycocyanobilin, was cleaved from the protein with methanol, concentrated hydrochloric acid, or subtilisin BPN’. The pigments obtained were converted to their dimethyl esters and purified by preparative high pressure liquid chromatography and examined for purity by analytical high pressure liquid chromatography on silica gel. They were characterized by proton t...

PURPOSE This study was designed to examine the constrictive potential of C-Phycocyanin (C-PC) in regulating changes imposed on gene expression in the selenite-induced cataract model. METHODS Wistar rat pups were divided into three groups of eight each. On P10, Group I received an intraperitoneal injection of normal saline. Groups II and III received a subcutaneous injection of sodium selenite...

Abstract The article presents the results of studying degree destruction phycocyanin in composition protein module under various pasteurization modes. objects study were: dry sodium caseinate with a mass fraction 85%, whey concentrate 80% matter, extract containing 42.7 wt.% phycocyanins. 1% aqueous solutions were prepared from each object. Sorption by matrix was carried out combining an soluti...

Resonance-enhanced coherent anti-Stokes Raman spectra are recorded for monomers and trimers of phycocyanin from three different cyanobacteria: Westieflopsis prolijica, Mastigoc/adu.s faminosus and Spirulina platensis. It is shown that upon aggregation from monomer to trimer the electronic structures of both the a84 and 684 chromophores are changed. The spectra of the trimers originating from S....

Rapid and sensitive methods for the detection and genetic characterization of cyanobacteria have been developed based on DNA amplification techniques. This article describes the molecular methods that have been used to characterize cyanobacteria and their use as tools to identify toxin-producing strains. Different species and strains were compared using restriction fragment length polymorphism ...
